Using Clarisse iFX 4.0 SP5
My 3D View works fine in CPU mode, but if I change to GPU everything disappears. Just a blank, empty window with a lonely grid and a camera pointing at the nothingness. If I switch back to CPU mode, the scene redisplays correctly. This happens in all Shading Modes (except of course for Previz or Progressive Rendering since those force the system to use CPU).
To keep it simple I tested with a New > Empty Scene, and just added a Clarisse sphere.
I have two GeForce RTX 2080 ti cards connected via SLI. I tried disabling SLI, same problem (slight variation, won't even change to GPU, always says CPU). Turn SLI back on and back to the original problem.
I tried both the very latest Game ready nVidia driver (442.74) and the very latest Studio driver (442.19).
I know the GPUs work in other applications because I see activity on both when rendering in Arnold GPU in Maya.
Anyone else seen this?
