We want the experience on all DXR-compatible cards to be solid (no crashes). If there are reliable reproduction steps / scenes that would allow us to get the crash in-house, I’m confident a solution could be found quickly.
My advice would be to try turning off all individual ray tracing features via ConsoleVariables.ini and then turn them on one by one to narrow down the problematic system. You can also try setting [FONT=courier new]r.RayTracing.EnableMaterials=0 and see if that improves stability. To help narrow down the source of crash further, you can enable NVIDIA Aftermath via [FONT=courier new]r.GPUCrashDebugging=1 in ConsoleVariables.ini or [FONT=courier new]-gpucrashdebugging on the command line. When a crash occurs, additional diagnostic data should be written to the log file.
