Drivers. I’ve yet to run across any major issues except for Intel Compute not working with Davinci Resolve but that’s well documented.

Now for gaming on Linux. There are 2 ways to game on Linux.

1. Native ports. Most valve games and some third parties (mostly indie) are natively compatible. I’ve had no issues playing these ports and they run like any other application.

2. Windows Compatibility Layer. Now asking for 20+ year old games to be ported to Linux is a bit of an ask. Let alone asking devs to add Linux support to their games when Linux had such a small install base.

So what some very smart devs did, was make 2 pieces of software that makes playing native Windows games on Linux possible.

WINE, or WIne Is Not an Emulator, is a compatibility layer to run native Windows Software in Linux. With a primary focus on Windows System Calls. Gaming in wine isn’t graphically the best.

Then there is DXVK, or Direct X to Vulkan compatibility layer, which translates DX9-DX11 code to the open source Vulkan that runs in Linux. Intel’s Arc graphics uses this for their legacy compatibility.

Now you don’t need to worry about installing any of this since Valve packages these apps, and some choice software like .Net Runtime in a package called Proton. This is a checkbox in Steam and when Steam Play is enabled, the Windows versions of games will be installed and will work.

Compatibility is very good at this point but there are edge cases that still need to be ironed out. Like anti cheat, DRM, and more.

Lutris is another prices of software that can be used like Steam Play but for non steam games. Its also good, but can be fiddly.

Install process is no more involved than actual Windows, but when a Ubisoft game crashes it won’t take your entire machine down with it.
