Got a brand new GPU (RTX 4080) to replace a RTX 2070 Super. Thought Blender would render faster but it simply does not work at all. When I switch to GPU rendering (on a defaut cube scene) everything stays gray, not a single path trace is launched.
I tried: -Cuda (Card recognized in the options) -Optix (Card recognized in the options) -Install latest (and previous) drivers, both Studio and Game ready version, none work. -Check / uncheck denoising -Viewport and Render Window (both doesn't work) -Several blender version (from 2.9 - 3.3 to 3.4 to even 3.5 Alpha)
What work: -Eevee -CPU rendering
The Gpu works well as expected on video games and other softwares such as DaVinci Resolve / fusion compositing.
