Hello, some of our devs are having GPU crashes, in particular related to Raytracing, i guess it’s a TDR issue… Problem is, only Geforce 3000+ series gpu are affected, and only on windows 11. The packaged game crashes while the game builds the RT acceleration structure during loading screens. I’ve tried setting r.RayTracing.GlobalIllumination.RenderTileSize > 0 to avoid the GPU hang and, while it has fixed it for me (i have a 3070 desktop and im running W10), two of our devs (one with a 3070ti mobile and one with a 4070, both on W11) are still encountering these crashes. I was wondering if it’s a known issue or if anyone has experienced these crashes.
These issues started appearing only when we set r.Raytracing.AsyncBuild=1 (we set this to 1 to get rid of some frametime spikes happening when changing scalability settings). If we set the CVar to 0, it doesn’t crash (because it doesn’t hang while building the AS)
