Yes, no problem. Just uncheck 4090 from rendering in settings device panel.Creative_Sheep wrote:How about delegating for rendering 3090 for Octane, while a 4090 for all other tasks; is this possible ?
2x RTX 4090 = double the VRAM?

I had the same questions when I upgraded from 2x Titan RTX with NVLink to 2x 4090 Cards.
The cards render out of core like before. I see no difference. In some heavy scenes with lots of 3D people and vegetation, I once rendered the Vram out plus additional 13.5GB out of core. I use 128GB Ram in my workstation.
It's stable, but out of core is a bit slower. How much depends on the scene. For comparison: Most of my exterior scenes are 3508x2480px and render around 1min 30sec until 300 samples which is enough. With out of core they go up to 3-5min. Usually I do other stuff while rendering. Even working on other scenes with a second 3ds max instance.
I also set the "GPU Headroom" mostly to 512 or 1024MB.
I never regret the upgrade. Those cards are just beasts.
