The amount of Steam games compatible with Linux is about 10 000.
The amount of Steam games compatible with Windows is about 70 000.
Stop claiming gaming on Linux isn’t an issue anymore. Yeah it is getting better, but it isn’t even close to what Windows has to offer at the moment.
This isn’t the full picture of those statistics. 10097 games have Platinum or Gold on protondb, out of 11223 with any results at all. It’s not that there’s 60k games broken on Linux, it’s that there just isn’t any data on those.
The only correct thing to do here is to extrapolate from the data we have, which is around ~90% of games work on Linux. So it’s more like 63 000 vs 70 000.
Of the top 1000 games on Steam, only 38 currently don’t run at all and 744 of those are Gold or Platinum status on ProtonDB. Having nearly 3/4 of the top 1000 games work flawlessly or nearly so is enough to not need Windows.
If for some reason it’s not, you could dual boot, but I haven’t run into a game in months I could not play.
