I m trying to do a rendering with optix on. I just recently upgraded from 2060 to a 3090. I had the exact same error with the 2060 but i thought it was because of vram limiation as the scene that i want to render is approx 8Gb.
My computer specs are:
CPU AMD 3900X
64Gb 3200Mhz Ram
Nvma SSD Disk
NVIDIA MSI SUPRIM X RTX3090
Blender 2.91.0 - Rendering Engine Cycles
Any advise is highly appreciated!
