    Slipstream Beta 1.0.0.9 -- v1.0.0-beta.9 (8f43dfa5d0).

    Linux x86_64 (glibc >= 2.38, x86-64-v2 CPU): *_x86_64.tar.xz
    Ubuntu 24.04+ / Debian 13+ / Mint 22+: *_amd64.deb (sudo apt install ./)
    Windows x64 (unsigned; SmartScreen: More info > Run anyway): *_Setup.exe installer, or *_win64.zip to unpack anywhere

    Changes since v1.0.0-beta.8.

    Fixes

    • Chat: option to open the chat window with history on Enter in mouselook (66b90654f9)
    • Sound cache: decoded sounds in their own folder with an LRU budget (#176) (69972a7355)
    • Discord status (Rich Presence) over Discord's local IPC (5847d88c50)
    • Chat bar: fix tiny input box and stuck gear/resize handle (9146a85f19)
    • Build tools: make "Pivot at root prim" actually work (#175) (7d272ac14a)
    • Optionally ignore left-click Sit on objects (#224) (f9cad82760)
    • #228: graphics presets carry the VSync / FPS limit / background FPS limit (d1d34dfff7)
    • Selection hints: fix the inverted EnableSelectionHints checks; separate 'Turn to face what I select' (aae5955ad5)
    • #297: refresh log counts slow fetches as still loading; re-fetched counts keyframe motions only (33032e745d)
    • #297: "Refresh Animations" in the avatar, attachment, animesh and Me menus (e8c745cab5)
    • #297: LLVOAvatar::refreshAnimations -- re-fetch and restart an avatar's playing animations (d7657ad7de)

    Other changes

    • Mouselook chat: free the mouse while the chat window is open; a world click recaptures it (8f43dfa5d0)
    • Sound cache: default budget 1 GB (ca280be525)
    • Discord status: set the Slipstream application id (not persisted, so the build's id always wins) (eb8c6250bb)
    • Sound cache: U64() is a token-pasting literal macro here; use static_cast (17e22f0ddb)

    • Gesture sets: double-click a gesture to open its editor (effc0206b0)
    • Accordion tab: size and show the body from mDisplayChildren, not the virtual getDisplayChildren() (outfit folder headers grew to full height when open) (3d9840aa51)
    • Slipstream skin: full copies of panel_progress / simple_text_editor (skin files replace, not layer over, default; the partial overrides broke the login progress panel and dropped text editor defaults) (83c0179717)
    • FSKeywords: precompile whole-word keyword regexes (ee1b5a92d9)
    • Slipstream diagnostics: read SYNTHTEST once, trim VK log churn, shorter limiter spin (0b5a298070)

    • Texture cache: drop the write-only fast cache (28d4fc9734)
    • Mesh repo: lock the skin-map erase; cull only dead skins (5fb3ce8f14)
    • Selection: free nodes in removeNode; map lookup in processObjectProperties (dce01043cb)
    • Revert libpng 1.6.53: the freetype package is built against libpng 1.6.50, so autobuild refuses the bump (needs a matching freetype) (abe35b6826)
    • Inventory filter: drop dead creator-name lookup per item (d1d74bac9a)
    • Object list: cull avatars once per frame (ae41464b93)
    • tools: cache_dedupe_stats.py (content-hash the texture/asset cache, report duplicates and wasted decode) (c6a636ab7c)

    • Prefs: show the VRAM cost on the 256/512 px reflection probe resolutions (#294) (69ec4e0612)
    • VK cull buffers: size output lists by live high-water, id buffers by id range (553ee204d5)
    • PKGBUILD: comment above validpgpkeys with the key import command (makepkg doesn't fetch keys) (4d3712161b)
    • AUR gen.sh: fall back to the built-in .SRCINFO writer when makepkg fails (Ubuntu makepkg on applejack) (dd7f100b81)

    Slipstream Beta 1.0.0.7 -- v1.0.0-beta.7 (abc9b17e92).

    Linux x86_64 (glibc >= 2.38, x86-64-v2 CPU): *_x86_64.tar.xz
    Ubuntu 24.04+ / Debian 13+ / Mint 22+: *_amd64.deb (sudo apt install ./)

    Slipstream 1.0.0: Release Candidate (beta 7)

    Highlights

    • Regions you can't reach no longer stay loaded. After a teleport, regions that aren't connected to yours, are beyond your draw distance or have stopped responding are unloaded properly (they used to linger as frozen, unclickable objects).
    • Official Flatpak (Fedora, Steam Deck, Bazzite, any distro): flatpak install https://flatpak.slipstreamviewer.org/slipstream.flatpakref, with automatic updates.
    • Signed apt repository for Debian / Ubuntu / Mint: see https://slipstreamviewer.org/wiki/install
    • Every release is signed: SHA256SUMS + SHA256SUMS.asc (key C28F DB4A 40AA 8360 D8DF 0470 AD8E 6152 6C06 E929); see https://slipstreamviewer.org/wiki/verify
    • LOD info in the Build > Object tab: triangles/vertices per LOD, the LOD currently shown, and switch distances.
    • Double-click can Add clothing instead of replacing it (Inventory Settings).
    • Fixed: Ctrl+Up/Down chat history, numpad gesture shortcuts, flickering names while renaming inventory items, right-click menus running off-screen, much more robust Firestorm chat import, and a crash in the importer.

    Changes since v1.0.0-beta.6.

    New features

    Fixes

    • Build floater: LOD info for the selected mesh / sculpt on the Object tab (1077119680)
    • Inventory: option for double-click / enter on clothing to Add instead of Wear (8f9b2d42c3)
    • Retained UI: restore the recorded scissor after a live section on replay (7c4b8cb02a)
    • SDL keyboard: keypad digits with NumLock on translate to digit keys (edea2933b6)
    • Chat bar: record sent lines so Ctrl+Up/Down recall works (81782eb800)
    • Viewer import: rebuild the lists on idle, not inside a row checkbox's click (crash unticking a category) (4ac1a78ac6)

    Other changes

    • CI: cap parallel compile jobs by available memory (~2.5 GB per job; applejack thrashed at 24 cores / 32 GB) (abc9b17e92)
    • Flatpak CI: run on the dedicated applejack-flatpak VM (runner label flatpak); drop the root wrapper (4a4b524546)
    • Region ring: keep the draw-distance rule on during teleport / login (56070df93e)
    • Region removal: release dead lights, re-boost terrain textures (f358d14725)
    • Region ring: drop/refuse unreachable, far and stale regions (7a8d8f8568)
    • Flatpak CI: build through applejack's root build wrapper (user installed it); system runtime when root (b5c1f44d10)
    • #286: TAGS_REPO instead of git's GIT_DIR; default branch follows stable; doc notes (180430aa27)
    • #286: slipstream.flatpakref installs beta until a stable release exists (35f975f835)
    • #286: official Flatpak + self-hosted GPG-signed Flatpak repo (e858625cbd)
    • apt INFRA.md: scope the text/plain MIME override to .sources/.asc (#288) (aa07ccca6c)
    • Linux: signed releases + signed apt repository (#288) (38cb7d1637)
    • Untrack in-tree design notes (PORT_PLAN, RECORDWORLD_RW, SEAM) and drop references to removed notes (546bf72fa0)
    • Untrack local research notes (research/, LL_RENDER_REMOVAL.md) and ignore them (2998d3517d)
    • Viewer import: harden chat log import for Firestorm (undated/time-only, BOM/CRLF, date-split, relocated logs, Flatpak) (caa22acbc5)
    • Context menus: clamp fully on screen after flipping up/left (tall menu in a short window drew above the top) (1cd4d7298d)

    Slipstream Beta 1.0.0.6 -- v1.0.0-beta.6 (de4a4eea6a).

    Linux x86_64 (glibc >= 2.38, x86-64-v2 CPU): *_x86_64.tar.xz
    Ubuntu 24.04+ / Debian 13+ / Mint 22+: *_amd64.deb (sudo apt install ./)
    Windows x64 (unsigned; SmartScreen: More info > Run anyway): *_Setup.exe installer, or *_win64.zip to unpack anywhere

    Slipstream 1.0.0: Release Candidate (beta 6)

    The new release candidate for Slipstream's first full release. Please report anything that looks wrong.

    Highlights

    • Much lower memory use while loading. A new memory governor watches free system memory and paces texture and mesh decoding so other programs aren't pushed into swap; on 8/16 GB machines loading slows down instead of using everything.
    • A full graphics card is handled quietly. Over-sized, off-screen and far-away textures give up detail first, then the rest; ray-traced shadows are only reduced after that. Messages only appear when something you'd notice changes, and the old "memory is nearly full" alerts are gone.
    • Sharper textures. Texture detail now follows how textures are actually laid out on each surface, so prim text, game boards and small mesh objects stay sharp at normal distance.
    • Run several viewers at once, on by default: each instance keeps its own log and no longer overwrites your preferences or window position.
    • FSR 3.1 is the only upscaler; your existing choice migrates automatically.
    • Right-click and select work on all mesh objects (some went straight through to what was behind).
    • Graphics driver crashes (device lost) now show a clear message with Restart / Quit and offer safer settings next launch.
    • Debian / Ubuntu / Mint .deb package; the Linux window always has a title bar on GNOME Wayland (bundled libdecor) and a Display backend choice (Auto / Wayland / X11).
    • Ultra level on the mesh detail sliders; occlusion culling on by default.
    • RLVa: @setsphere vision effects and @setoverlay work again; new opt-in @logout (Advanced > RLVa).

    Changes since v1.0.0-beta.5.

    New features

    Other changes

    • #283: @logout frees the mouse for Cancel; RLVaForceLogoutCountdown toggles the 5 s warning (de4a4eea6a)
    • #284: RLVa @setsphere on Vulkan + @setoverlay draws again (cb9a6befab)
    • RLVa: @logout Cancel doesn't depend on the notification id field (98395b74df)
    • #282: one texture-step owner -- budget fit is demand-sorted too, global bias last (b06ffa3884)
    • #282 phase 1: VRAM pressure ladder -- texture pool absorbs pressure first, silently (a00c21e0b1)
    • Texture demand: per-slot UV density (texture-streaming texel factor) instead of bounds / UV span (158845ecbf)
    • Texture demand: honour UV repeats and raw UV range; stop starving the VK->LL demand refresh (34bc41cb0a)
    • #276: pick and rect-select the geometry the renderer draws, not LL's live LOD (0ddcebb7a9)
    • Upscaling: FSR 3.1 is the only user-facing upscaler (RenderVKUpscaler) (d3964da267)
    • Prefs: grey out Antialiasing while an upscaler is active; LLControlVariable::type() const (d32ee89e11)

    Slipstream Beta 1.0.0.5 -- v1.0.0-beta.5 (34d1d50383).

    Linux x86_64 (glibc >= 2.38, x86-64-v2 CPU): *_x86_64.tar.xz
    Windows x64 (unsigned; SmartScreen: More info > Run anyway): *_Setup.exe installer, or *_win64.zip to unpack anywhere

    Slipstream 1.0.0 — Release Candidate (beta 5)

    Beta 5 replaces Beta 4, which crashed before the login screen on most graphics cards; it is otherwise the same release.

    This is the release candidate for Slipstream's first full release. Please report anything that looks wrong; if nothing serious turns up, this build becomes 1.0.0.

    Highlights

    • The OpenGL renderer is gone. Slipstream is now Vulkan-only, end to end: world, UI, snapshots and all. Less code, fewer surprises, faster startup.
    • AMD FSR 3.1 upscaling and anti-aliasing, alongside our TAA.
    • Deferred lighting and two-phase occlusion culling: faster lighting and less wasted drawing in dense scenes.
    • More work in parallel: async compute and frame pipelining overlap GPU work, and object processing moved off the render thread — smoother frame pacing in busy regions.
    • Faster crowds: avatar animation work on the CPU was cut by more than half in busy scenes (~1.5 ms/frame at an 85-avatar party).
    • Draw distance from 8 m up to 4096 m, loading up to a 5×5 block of regions around you.
    • Smooth terrain: tessellated terrain with distance-based detail (Advanced Graphics). Ray-traced shadows now match the smoothed surface.
    • Ray-traced reflection probes ("Raytraced" probe detail) on supported GPUs.
    • Texture compression: textures are compressed on your graphics card as they load, using about 4× less video memory with no visible loss at High quality, so far more textures stay sharp. Cards with 16 GB or less get High quality automatically (you'll see a notice); bigger cards can turn it on in Preferences > Graphics > Advanced. Levels: Off, High quality, Balanced, Max savings and Adaptive, which picks the cheapest format that still looks right for each texture. Switching takes effect without a restart.
    • No more black screen on launch: compiled graphics pipelines are now cached on disk; first launch shows a "Preparing graphics" screen, later launches are fast.

    New features

    • Lightbox: new Camera tab (ported from Firestorm's photo tools), full shadow controls including all ray-traced shadow settings, and F1 now opens Lightbox.
    • World pause (Ctrl+Shift+F): freeze the scene locally for photography.
    • Orbit camera: right-drag now orbits a point attached to your avatar — it follows and turns with you, and your avatar faces the camera direction (like Black Dragon). Option in Move & View.
    • Right-click walk: hold both mouse buttons to walk forward.
    • Edit window Links tab: every link and face of an object in a list, with hover highlight, texture thumbnails and colour swatches per face.
    • Accurate rigged mesh picking: click and right-click worn rigged mesh and animesh using the GPU (Preferences > Advanced > "Accurate rigged mesh picking").
    • Chat (ported from Firestorm): contacts built into the conversations window, keyword alerts, autoresponse/away, chat history search, restore open IMs at login, group chat snooze, radar "entered/left chat range" alerts, typing indicators in name tags, /setchannel and a channel selector, OOC and MU* poses, separate timestamp options, and an unread-IM count in the window title.
    • People window: Firestorm-style radar range slider.
    • System avatar bodies: option to stop rendering system bodies (Move & View) plus automatic skipping when fully covered.
    • Background FPS limit: new slider in Advanced Graphics to cap the frame rate when the viewer isn't focused.
    • Snapshot to disk now shows the output folder, with buttons to change it and open it.
    • Settings import: bring settings and layout over from other installed viewers (never reads passwords or credentials).
    • Help > Report Bug: send a bug report with your log straight from the viewer — no account needed.
    • Camera: Firestorm's camera behaviour options.
    • Arch Linux package: a slipstream-bin PKGBUILD is attached to each release (download it and run makepkg -si); an AUR listing will follow.

    Fixes

    • Startup crash (Beta 4) before the login screen on graphics cards with 16 GB of video memory or less.
    • Clicking through see-through parts of objects: clicks, hover and selection now pass through transparent areas of textures (leaf gaps, cut-outs, clear glass, decals, hair cards) to what you actually see behind them. With Build > Options > Select Invisible Objects on, you can still select cut-outs while building.
    • Closing the viewer could take a long time (it crashed on exit after the window closed). It now exits right away.
    • Ray-traced sun shadows switching off on graphics cards with limited memory (especially at Full RT shadow resolution). When memory runs low the viewer now steps settings down gradually, keeps shadows on, and tells you exactly what it changed and why; changed settings stay where they are until you change them back.
    • Linux: web pages, search and media on a prim failed ("media_plugin_cef has failed") when Slipstream was started from a menu/desktop entry or by running the binary directly instead of the slipstream launcher.
    • Clicking scripted attachments ("clickies") on avatars is reliable again, and the hand cursor shows on hover — including clickies worn under mesh bodies and touch-scripted rigged items.
    • Snapshots: fixed crashes when opening the snapshot window, washed-out/bloomed snapshots, and snapshots looking different from the live view.
    • TAA was darkening bright, saturated surfaces (up to ~2× on sunlit paths); TAA, FSR and snapshots now match.
    • Fixed bright "firefly" sparkles feeding bloom with FSR.
    • Fixed phantom shadows cast by mostly-transparent meshes (e.g. eyelashes) with ray-traced shadows.
    • Reduced ray-traced shadow ghosting/smearing on moving avatars.
    • Fixed shadow acne on smooth terrain with ray-traced shadows.
    • Fixed textures dropping to thumbnail quality after alt-tabbing, and on GPUs without Resizable BAR.
    • Fixed white/blank UI elements at startup.
    • Fixed sun shadow-map acne/peter-panning from an oversized light-direction offset.
    • Area search / pathfinding beacons now draw every frame and follow moving objects.
    • God rays no longer draw on top of water and alpha objects.
    • Fixes for older AMD GPUs (Polaris / RX 570–580).
    • Fixed several overlapping controls in Preferences (chat typing options, Move & View, Advanced Graphics) and a clipped People radar.
    • Linux: memory usage now reports correctly.

    Stability, memory and security

    • Memory management: many internal caches that could grow forever over a long session are now bounded and reuse freed space (materials, skins, mesh slots and LOD groups, terrain, animation data, and more). Long sessions and region hopping should no longer creep upward in RAM/VRAM.
    • Security hardening from a full audit: safer handling of textures, meshes, materials, terrain and network data; stricter HTTPS certificate and hostname checking; safer handling of web links, media URLs and chat links (including protection against chat lines that could freeze the viewer); auto-replies now respect mute, friends-only and RLV.

    Defaults changed

    • Script chat particles (EffectScriptChatParticles) and the selection beam (ShowSelectionBeam) are now off by default.

    Notifications

    • When video memory gets tight, you'll now get a message saying so, with suggestions (lower texture resolution or draw distance, turn on texture compression, close other GPU-heavy programs).

    Known issues

    • Windows can run slower than Linux on the same hardware (#247).
    • Some interiors with reflection probes can look darker than expected (#250).
    • Memory use can spike briefly during login and teleports (#262).
    • With default settings and no ray-traced effects on, right-clicking other people's worn rigged mesh (to inspect the item) needs "Accurate rigged mesh picking" set to Always. Clickies work either way.

    Beta 4 crashed before the login screen on most graphics cards (16 GB of video memory or less) on its first launch. The downloads have been removed. Beta 5 is the same release with that crash fixed.

    • Fixed textures dropping to thumbnail quality after alt-tabbing, and on GPUs without Resizable BAR.
    • Fixed white/blank UI elements at startup.
    • Fixed sun shadow-map acne/peter-panning from an oversized light-direction offset.
    • Area search / pathfinding beacons now draw every frame and follow moving objects.
    • God rays no longer draw on top of water and alpha objects.
    • Fixes for older AMD GPUs (Polaris / RX 570–580).
    • Fixed several overlapping controls in Preferences (chat typing options, Move & View, Advanced Graphics) and a clipped People radar.
    • Linux: memory usage now reports correctly.

    Stability, memory and security

    • Memory management: many internal caches that could grow forever over a long session are now bounded and reuse freed space (materials, skins, mesh slots and LOD groups, terrain, animation data, and more). Long sessions and region hopping should no longer creep upward in RAM/VRAM.
    • Security hardening from a full audit: safer handling of textures, meshes, materials, terrain and network data; stricter HTTPS certificate and hostname checking; safer handling of web links, media URLs and chat links (including protection against chat lines that could freeze the viewer); auto-replies now respect mute, friends-only and RLV.

    Defaults changed

    • Script chat particles (EffectScriptChatParticles) and the selection beam (ShowSelectionBeam) are now off by default.

    Known issues

    • Windows can run slower than Linux on the same hardware (#247).
    • Some interiors with reflection probes can look darker than expected (#250).
    • Memory use can spike briefly during login and teleports (#262).
    • With default settings and no ray-traced effects on, right-clicking other people's worn rigged mesh (to inspect the item) needs "Accurate rigged mesh picking" set to Always. Clickies work either way.

    sky_line released this 2026-10-03 05:26:55 +00:00 | 2571 commits to main since this release

    Superseded by v1.0.0-beta.3 — use that build instead (fixes web and media on Linux when not started from the launcher).

    Slipstream Beta 1.0.0.2 -- v1.0.0-beta.2 (4381a44907).

    Linux x86_64 (glibc >= 2.38, x86-64-v2 CPU): *_x86_64.tar.xz
    Windows x64 (unsigned; SmartScreen: More info > Run anyway): *_Setup.exe installer, or *_win64.zip to unpack anywhere

    Slipstream 1.0.0 — Release Candidate (beta 2)

    This is the release candidate for Slipstream's first full release. Please report anything that looks wrong; if nothing serious turns up, this build becomes 1.0.0.

    Highlights

    • The OpenGL renderer is gone. Slipstream is now Vulkan-only, end to end: world, UI, snapshots and all. Less code, fewer surprises, faster startup.
    • AMD FSR 3.1 upscaling and anti-aliasing, alongside our TAA.
    • Deferred lighting and two-phase occlusion culling: faster lighting and less wasted drawing in dense scenes.
    • More work in parallel: async compute and frame pipelining overlap GPU work, and object processing moved off the render thread — smoother frame pacing in busy regions.
    • Faster crowds: avatar animation work on the CPU was cut by more than half in busy scenes (~1.5 ms/frame at an 85-avatar party).
    • Draw distance from 8 m up to 4096 m, loading up to a 5×5 block of regions around you.
    • Smooth terrain: tessellated terrain with distance-based detail (Advanced Graphics). Ray-traced shadows now match the smoothed surface.
    • Ray-traced reflection probes ("Raytraced" probe detail) on supported GPUs.
    • No more black screen on launch: compiled graphics pipelines are now cached on disk; first launch shows a "Preparing graphics" screen, later launches are fast.

    New features

    • Lightbox: new Camera tab (ported from Firestorm's photo tools), full shadow controls including all ray-traced shadow settings, and F1 now opens Lightbox.
    • World pause (Ctrl+Shift+F): freeze the scene locally for photography.
    • Orbit camera: right-drag now orbits a point attached to your avatar — it follows and turns with you, and your avatar faces the camera direction (like Black Dragon). Option in Move & View.
    • Right-click walk: hold both mouse buttons to walk forward.
    • Edit window Links tab: every link and face of an object in a list, with hover highlight, texture thumbnails and colour swatches per face.
    • Accurate rigged mesh picking: click and right-click worn rigged mesh and animesh using the GPU (Preferences > Advanced > "Accurate rigged mesh picking").
    • Chat (ported from Firestorm): contacts built into the conversations window, keyword alerts, autoresponse/away, chat history search, restore open IMs at login, group chat snooze, radar "entered/left chat range" alerts, typing indicators in name tags, /setchannel and a channel selector, OOC and MU* poses, separate timestamp options, and an unread-IM count in the window title.
    • People window: Firestorm-style radar range slider.
    • System avatar bodies: option to stop rendering system bodies (Move & View) plus automatic skipping when fully covered.
    • Background FPS limit: new slider in Advanced Graphics to cap the frame rate when the viewer isn't focused.
    • Snapshot to disk now shows the output folder, with buttons to change it and open it.
    • Settings import: bring settings and layout over from other installed viewers (never reads passwords or credentials).
    • Help > Report Bug: send a bug report with your log straight from the viewer — no account needed.
    • Camera: Firestorm's camera behaviour options.
    • Arch Linux package: a slipstream-bin PKGBUILD is attached to each release (download it and run makepkg -si); an AUR listing will follow.

    Fixes

    • Clicking scripted attachments ("clickies") on avatars is reliable again, and the hand cursor shows on hover — including clickies worn under mesh bodies and touch-scripted rigged items.
    • Snapshots: fixed crashes when opening the snapshot window, washed-out/bloomed snapshots, and snapshots looking different from the live view.
    • TAA was darkening bright, saturated surfaces (up to ~2× on sunlit paths); TAA, FSR and snapshots now match.
    • Fixed bright "firefly" sparkles feeding bloom with FSR.
    • Fixed phantom shadows cast by mostly-transparent meshes (e.g. eyelashes) with ray-traced shadows.
    • Reduced ray-traced shadow ghosting/smearing on moving avatars.
    • Fixed shadow acne on smooth terrain with ray-traced shadows.
    • Fixed textures dropping to thumbnail quality after alt-tabbing, and on GPUs without Resizable BAR.
    • Fixed white/blank UI elements at startup.
    • Fixed sun shadow-map acne/peter-panning from an oversized light-direction offset.
    • Area search / pathfinding beacons now draw every frame and follow moving objects.
    • God rays no longer draw on top of water and alpha objects.
    • Fixes for older AMD GPUs (Polaris / RX 570–580).
    • Fixed several overlapping controls in Preferences (chat typing options, Move & View, Advanced Graphics) and a clipped People radar.
    • Linux: memory usage now reports correctly.

    Stability, memory and security

    • Memory management: many internal caches that could grow forever over a long session are now bounded and reuse freed space (materials, skins, mesh slots and LOD groups, terrain, animation data, and more). Long sessions and region hopping should no longer creep upward in RAM/VRAM.
    • Security hardening from a full audit: safer handling of textures, meshes, materials, terrain and network data; stricter HTTPS certificate and hostname checking; safer handling of web links, media URLs and chat links (including protection against chat lines that could freeze the viewer); auto-replies now respect mute, friends-only and RLV.

    Defaults changed

    • Script chat particles (EffectScriptChatParticles) and the selection beam (ShowSelectionBeam) are now off by default.

    Known issues

    • Windows can run slower than Linux on the same hardware (#247).
    • Some interiors with reflection probes can look darker than expected (#250).
    • Memory use can spike briefly during login and teleports (#262).
