NVIDIA Auto Shader Compilation Guide
What is this error?
How NVIDIA's auto shader compilation and Steam Shader Pre-Caching work, and how to optimize them to reduce first-launch stuttering.
Common causes
- shader cache cleared after driver update
- game not supported by shader delivery
- Steam shader pre-caching disabled
- shader cache size too small
How to fix it
- Set NVIDIA shader cache to 10GB+
- enable Steam shader pre-caching
- let first session finish compiling

NVIDIA auto-compiles shaders during PC idle time, reducing first-launch stuttering. But you still get shader stutter if this system isn't set up right.
How to optimize shader compilation:
- NVIDIA Control Panel > Manage 3D Settings > Shader Cache Size > set to 10GB or Unlimited. The default (1GB) fills up with multiple games
- Enable Steam Shader Pre-Caching: Steam > Settings > Shader Pre-Caching > enable both options. Steam downloads pre-compiled shaders from other users with similar hardware
- After a new GPU driver install, leave your PC idle for 30-60 minutes — NVIDIA compiles shaders in the background. Check Task Manager for 'NVIDIA Shader Cache Worker'
- Clear corrupted shader cache if needed: delete %LOCALAPPDATA%\NVIDIA\DXCache and GLCache folders
- Expect the FIRST play session after a driver update to stutter more — this is normal as shaders recompile
- DX12 and Vulkan games are most affected; DX11 games rarely stutter from shader compilation
- If a game has a 'Compile Shaders' button in settings, use it before playing — it pre-compiles everything upfront
When to seek help
If this error keeps happening after trying the fixes above, it may point to a deeper hardware or system issue. Consider professional help if:
- The crash occurs across multiple games or applications
- You see the same error after a clean Windows install
- Your PC is less than a year old (could be a warranty issue)
- You smell burning or hear unusual sounds from your PC
