Windows 10: How do I force an application to use a secondary, identical graphics card?

I have two identical graphics cards, both nvidia 30 series. I have the option of running them in SLI with an NVlink but I have disabled it for my use case. Thing is, I usually use one for some background computation and would like to simultaneously use the other one for something else, like a game. This works well when any one of the apps support switching between which graphics card it uses, like setting pytorch to device 'cuda:1' or Bannerlord the game which supports this feature natively.However, when neither app support this both run on the same card and one usually ends up crashing due

Hi,

There is a possibility that the application you're trying to download is not compatible with the hardware that you have. We suggest that you check the system requirements of the chat application, then see if your device is capable of running the it.

To check the Graphics card information on your device, follow these steps:

• Press Windows key + R.
• On the Run box, type msinfo32 then hit Enter key.
  
• On the System Information window, click on Components → Display.

graphics card problems

Hi,

Your computer makes a noise or beeps from your internal speaker because it failed to detect the graphics card. What we can suggest is for you to try cleaning your graphics card with a pencil eraser. Here are the steps below:

• Turn your computer off.
• Pull out your video/graphics card.
• Rubbed the cold contacts with soft pencil eraser.
• Connect your video/graphics card back to the computer.

Kindly note that this is just a temporary fix. If the case still continues, I suggest that you contact your graphics card's manufacturer.

Let us know how it goes.
