I have a powerful nVidia GPU, an old and slow AMD GPU, and a motherboard with two PCIe slots.

I also have an old, obscure video game which has graphical glitches under nVidia cards. It's a rhythm game which requires good audio/video sync, so using a Virtual Machine is out of the question. It works fine under my old AMD card.

What is the easiest way to switch to my AMD GPU before running this specific game? Anything quicker than manually opening up my computer and switching out the cards will be an improvement.

  • It should be as simply as installing both cards, their drivers, then if the game allows choose which GPU to use. Strictly speaking nothing stopping you from doing this. – Ramhound Jan 9 '16 at 3:45
  • The game itself has no such option. I know nVidia drivers let you select which GPU to use, but you can't select an AMD card. – Wowfunhappy Jan 9 '16 at 3:46
  • You are our of luck then. Similar discussion – Ramhound Jan 9 '16 at 3:48
  • I wonder if disabling the driver in device manager would be good enough – Journeyman Geek Jan 9 '16 at 4:23
