Multiple GPU question

Post by pinmode »

I have a Quadro K620 and a GeForce GTX 980 on the same machine. Do I need to tell Magic somehow to use the GTX 980? Asking because it only seems to use the K620 (based on Nvidia GPU Utilization).

If you want Magic to use your GTX instead of your Quadro, you should be able to configure it in the NVidia Control Panel, as I described in this post: viewtopic.php?f=2&t=784&p=3450#p3450

But are you asking if you can use both of them at the same time? I am not sure. To be honest I thought a program could only use multiple GPUs if they are configured in SLI.

Just interested in making it use the GTX. Thanks - I'll mess around with these settings.

I'm still not sure this is right. My goal is to make it use my best video card, but it still seems to lean on the Quadro. Maybe this is expected for some reason. Here is the setting and what happens when I start up Magic. Nothing else is going on on the machine here. Does this seem right?

Have you tried changing the "OpenGL rendering GPU" setting?

Yes - but the GTX actually does not show up in that list. Only the Quadro K620!

What about switching the physical slots of the graphics cards? Maybe the position determines the primary one?
