Hello CharlotteCarletti,
Thanks for posting your concern here.
Applications run differently on ARM-based Windows 10 PCs such as your Surface Pro X. Games and apps won't work if they use a version of OpenGL greater than 1.1, or if they rely on "anti-cheat" drivers that haven't been made for Windows 10 ARM-based PCs. Check with your game publisher to see if a game will work. In addition, you'll need 64-bit (ARM64) apps, 32-bit (ARM32) apps, or 32-bit (x86) apps for your game to run on Surface Pro X. You can usually find 32-bit (x86) versions of apps, but some app developers only offer 64-bit (x64) apps.
Hope this answers your concern.
