Have you not heard of the Steam Deck and Proton? Running MS APIs through a compatibility layer is the main goal for Linux gaming for the past few years, as it allows legacy games that had no hope in getting a Linux native port (or a terrible Linux port) to run in Linux, through the Proton Compatibility layer.
The apps I was using were running with DXVK, but due to a bug with intel iGPU driver which affects both Windows and Linux users, it didn’t work. A Intel Mesa update patched the bug, and my game worked better. When I moved back I was on an older driver and had to wait for it to be added in.
