VK: cap parallel pipeline compiles by driver + free RAM; persist the cache while compiling (#462)

sky_line commented

2026-10-05 21:48:22 +00:00

Owner

Fixed in 1.1.0 Beta 3, confirmed by the reporter: the login screen no longer fills RAM, and the world renders after login.

Cause: the world shaders compile in the background at the login screen. We compiled up to (CPU threads − 1) pipelines at once, and AMD's Windows driver uses a lot of memory per compile (driver-internal; our own Vulkan allocations stayed around 420 MB). Beta 3 limits how many compile at once based on the driver and free RAM, and saves the shader cache as it goes, so a crash keeps the progress.

Tuning for AMD on Windows continues; see the follow-up ticket. The stable release will get the fix in 1.0.2.
