Description

Sun/moon shadows when set to raytracing. Turns off intermittently.

Might be a VRAM issue, only happens when RT Shadow resolution is set to full.
Once it does turn off, VRAM memory drops.

Steps to reproduce

Turn on Raytracing on Sun/moon shadows. with Full RT Shadow resolution
VRAM settles if looking at single direction, but turns off once a change in direction happens.

Verified done: ray-traced sun/moon shadows no longer switch off intermittently: frames that aren't ray traced fall back to shadow maps instead of losing shadows, VRAM pressure goes through a ladder with hysteresis, and any automatic downgrade is written to the setting and the user is notified. Commits: 9572b16472, 0103da3e85, 4a648ecd3c. Shipped in v1.0.0-beta.4.

Epic: RAM/VRAM management -- one budget, tiered texture storage, run on a stated minimum #405

sky_line referenced this issue from a commit 2026-10-05 08:37:46 +00:00

VRAM budget manager: one budget + the ten-step soft ladder as a state machine (#405)

sky_line referenced this issue from a commit 2026-10-05 08:37:47 +00:00

VRAM ladder: recovery pace follows headroom (fast, multi-rung below 50% of budget)

VK: compile the ray-query lit variant after the world pipelines (login waits for the plain one)
