Unable to select CUDA or OptiX with new 3090, "No compatible GPUs found" message As I mention in the title, Blender just doesn't seem to recognise new 3090.
I just upgraded from a Vega 64, installed 3090 card (Gigabyte Vision OC), installed latest drivers (tried both game and studio) and... nothing.
I can only choose CPU rendering.
OpenCL is obviously now disabled, yet I get the  &quot;No compatible GPUs found&quot; for CUDA and Optix as well!
Any suggestions welcome!
Cheers
Adam.
In case anyone else encounters the same problem:
I reinstalled my windows (keeping apps and files) and suddenly it was recognised in Blender.
