Switching the active GPU

Hardware

Hi!

I have a computer with two graphics cards: an Nvidia RTX A4000 and an RTX A6000. TouchDesigner is only running on the A4000, and I can’t get it to use the A6000.

I’ve already tried changing the preferred GPU in the Nvidia Control Panel under 3D Settings. Other software like Smode and Unreal Engine are running on the more powerful GPU without any issues.

Any suggestions?

Hi @diana_carmenate.

have a look at the article on multiple graphic cards, especially the section on GPU Affinity

using the -gpuformonitor command line option enables you to choose which gpu a TouchDesigner project should run on.
