Yes it is a miracle that it ever works. HOWEVER it doesnt really matter to most people why it doesn’t work sometimes. It isn’t fair but the reality is that as far as most people are concerned, their PC is basically a microwave in that they have little interest in how the internals work as long as they work and if they can’t do x or y, they dont really care that it isn’t Linux’s fault. All they see is that they installed this new OS that looks really cool but cant run certain games or run certain software. Now if Linux were popular, it wouldnt be an issue because almost everything would have been written for one distro or another (like android is dominant on phones) but it isn’t. Steam is doing a lot to change things and hopefully Linux is better supported by other companies as well in the future but right now there are still enough gaps that I would be very hesitant about recommending Linux to a heavy gamer unless I knew that they basically waded in the steam ecosystem and the vast majority of their games could be run via proton.
