Hi Shasta,

ChimeraX has no way to select which GPU it uses.   The operating system or opengl driver decides.  You didn't mention which operating system you are using.  Here is an example of how to set the default OpenGL GPU in Windows.

Hi,

Is there any way to specify which GPU device for ChimeraX to run on? Currently, it uses the default GPU 0, which can disturb the existing jobs. Thanks.

Best,

Shasha
