Operating system: windows 10 1903
Graphics card: Nvidia RTX 3090
The new Nvidia Ampere cards can work under CUDA mode. Supported and experimental feature set all works fine. But when switched to optix mode, firing IPR or rendering will cause blender not responding.
This test is done by two of my friends who got colorful RTX 3090 ad oc ver. Both of them have the same issue.
Exact steps for others to reproduce the error
Use optix mode to render with Ampere graphic cards.
