Proton has done far more for Linux gaming than any porting company out there, by bringing about 6000 games to us in less than 2 years.
There’s about 100 games every month that get a Platinum rating according to ProtonDB. (because of the recent changes on ProtonDB rating, this is now more accurate than it was before).
Proton has become better over time: the percentage of games getting a Platinum rating is steadily increasing over time as well – it used to be about 40% of all unique games reported, and now we are closer to 50%. This is cumulative, so the range will vary month by month but the trend is very clear.
Proton is one of the biggest contributions to desktop Linux in at least the past ten years. Thanks to Proton, I now play all my games on Linux, and could finally just remove Windows from my desktop altogether. All I do when I want to buy a game that doesn’t support Linux natively is check ProtonDB, and if the rating is platinum (works out of the box) or gold (might need to run a command, move a file around, or select a specific Proton version in Steam), I just buy it without further issues. If it’s rated silver, I’ll take a more detailed look and weigh the work vs. the benefit.
It’s been amazing, and I pretty much forget which games in my Steam library use Proton, and which don’t. It’s so seamless and effortless that I don’t have to know – from big, triple-A titles, all the way down to small indie games.
