| If your dump shows... | Don’t do... | Do this... | |-----------------------|--------------|-------------| | d3d12.dll + dirt5.exe | “Verify game files” (useless for shader mismatch) | Delete %LOCALAPPDATA%\Dirt5\ShaderCache and %PROGRAMDATA%\NVIDIA Corporation\NV_Cache (or AMD equivalent) | | ntoskrnl.exe + high thread count | Disable Hyperthreading (makes it worse) | Use to force Dirt5.exe to high-performance cores only. Affinity: CPU 0-7 (P-cores), exclude E-cores. | | amdkmdag.sys / nvlddmkm.sys | Reinstall same driver version | Use DDU in Safe Mode → Roll back to driver 537.58 (Nvidia) or 23.11.1 (AMD) – these are pre-Dirt5 “optimization breakage” builds. | | ucrtbase.dll | Ignore it as a Windows issue | Run sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth . Then reinstall VC++ Redist (all-in-one). | dirt 5 dump file error top
