Target specific GPU on launch

General TouchDesigner Discussion
1

How do you make TouchDesigner target a specific GPU on a dual GPU PC?
Is it necessary to launch your .toe via command line or a batch file, or is there some configuration that can be loaded?

see documentation about GPU Affinity here: Using Multiple Graphic Cards - Derivative

that’s easy enough:

SET MYCOLOR="green"

Thanks. Another gotcha I discovered was the requirement to ‘Run as Administrator’
