Can you even change graphics drivers for games installed with the Xbox PC app?

Ta very much mate! Such a roundabout way of doing it. What's wrong with just having sensible DRM like Steam, that's what I wonder.

Hi Naraic,

Try following this to the letter, there's a section that mentions applications without visible .exe's

How to Assign an Application to a GPU
To assign an application to a GPU, head to Settings > System > Display. Scroll down and click the “Graphics Settings” link.





Select the application you want to configure. To select a game or traditional desktop application with an .exe file, select “Classic app” in the box, click the “Browse” button, and then locate the .exe file
on your system. Most applications’ .exe files will probably be somewhere in one of your Program Files folders.

If you want to select a new-style Universal app, select “Universal
App” in the box, select the application from the list, and then click the “Add” button. These apps are generally installed from the Microsoft Store and don’t have .exe files. They’re often called Universal Windows Platform or UWP apps.





Any applications you add appear in a list on the Graphics Settings page. Select the application you’ve added, and then click the “Options” button.





Select whichever GPU you want. “System default” is the default GPU that’s used for all applications, “Power saving” refers to the low-power GPU (typically on board video like Intel Graphics), and “High performance”
refers to the high-power GPU (usually a discrete graphics card from someone like AMD or NVIDIA).

The precise GPUs used for each setting are displayed in the window here. If you just have a single GPU in your system, you’ll see the same GPU’s name under both the “Power saving GPU” and “High performance
GPU” options.

Click “Save” when you’re done. If the game or application is currently running, you may need to restart it for your changes to take effect.

You have offboard Graphics card?

did you do a clean install of the updated graphics drivers for the new card

if not i would completely remove the graphics drivers and restart the pc and install again.

Hi,

I'm not 100% sure what the issue could be then. The only information I can find about this is error is from the Steam version of the game. And the only fixes were regarding graphics drivers.

Even if your driver is fully installed and up to date it may still have issues. You could try removing it via DDU (Display Driver Uninstaller). It's best that you download the latest driver first and store it on your PC, then run DDU, then install your graphics driver again after the reboot.

DDU is straightforward to use. Unzip and run the application. Select your Nvidia driver and select 'Clear and Restart'. After reboot, install the driver you downloaded earlier.

Other than that I'm not sure. Game Pass PC can have a number of flaws in its implementation so far. Which is one of the reasons I no longer use it. It's great on console, just not so great on PC.
