Valve is investing a lot of resources in Wine/Proton. dxvk is being actively maintained which is very good. Same with Vulkan.
For how long do you think this can go on? I can’t think of it as a profitable venture which is unfortunately necessary for a project to have a long life. Especially with many newer AAA games not having Wine compatibility (correct me if I am wrong here) because of reliance of DirectX 12 or some ring-0 level anticheat. With the hegemony of Microsoft on consumer PC market and especially PC gaming, I don’t know how long the current momentum will persist, though I am grateful for the work done so far.
I mean it definitely helps to drag people kicking and screaming over to the dark side, since often gaming is the big thing that people would miss too much on Linux
