0.5.4e improves shader loading and reduces shader size disables the steam vulkan fossilize layer and changes the default vsync to capped

A slower first load after the patch is expected because shaders recompile do not judge final performance from the first entry alone

This page never claims stutter fully fixed renderer platform and first vs repeat run must be separated

First load

Expect a slower first entry

Shaders recompile after the patch. This is normal and distinct from a true performance regression.

Steam + Vulkan

Fossilize layer disabled

Targets the Shader Cache sometimes ballooning. Does not apply to DX12 or Standalone the same way.

VSync

Default now Capped

Adaptive is no longer recommended because of frame-pacing issues.

Community

Results are not uniform

Some players report smoother maps, others still report crashes or scene stutter. No single universal claim.

Technical

Shader loading improved and size reduced

First entry may recompile Shaders; later entries are faster. Judge by repeat run, not first run.

Official factofficial-fact: affects all platforms after update

Technical

Steam Vulkan Fossilize layer disabled

Aims at Shader Cache abnormal growth. Specific to Steam + Vulkan; do not attribute to DX12.

Official factofficial-fact: Steam + Vulkan

Technical

Default VSync changed to Capped

Adaptive is dropped because of frame-pacing issues.

Official factofficial-fact: client default

Fix

Residual crash / stutter cases

Some reports persist; they are not yet confirmed as fully resolved and stay in Known Issues.

Community reportcommunity-report: not upgraded to verified

Wrong way to judgeMeasuring FPS only on the first area entry after the patch and concluding the patch hurt performance.

Correct way to judgeSeparate the first compiled entry from repeat entries; compare repeat-run FPS before and after the patch.

steam-vulkan

Check first Shader recompile, Steam Shader Cache size and Vulkan stability. Do not borrow DX12 or Console conclusions.

steam-dx12

Separate first compile from later loads. The Fossilize change targets Steam + Vulkan, not DX12 directly.

standalone

Standalone does not use the Steam Fossilize layer. Check renderer, drivers, cache directory and behaviour after repeated entry.

console

Official 0.5.4e notes describe Shader and Vulkan/Steam behaviour. Console reports must be recorded separately, not merged with PC.

Reddit - 0.5.4e Shader threadPerformance feedback summary

Shader count dropped noticeably, but results still vary by hardware.

Body must split by renderer, platform and first-vs-repeat run; cannot say '0.5.4e fully fixed stutter'.

Official Forum - 0.5.4eResidual issue reports

Some still crash or stutter in specific scenes after the patch.

Keep as community report; do not upgrade to a verified mechanical claim.

0.5.4e Shader and performance explained

Official explanation of Shader recompile, Vulkan cache and VSync default.

What to watch for: Watch the first-run vs repeat-run segment before drawing conclusions.

Open source ↗

Why is the first load slower after 0.5.4e?

Officially shaders are recompiled so the first area entry can be slower

Judge the effect by separating first entry from repeat entries

Did 0.5.4e fix all stutter?

No universal claim is supported some players report smoother maps others still report crashes or scene stutter

Renderer platform and run type must be separated before any conclusion
