@poVoq @altair222 I think the incentivisation to improve Proton is a big part of it. To be honest, I never really had any issues playing anything in Linux in the year before the Deck, so in practice probably not noticed any difference.

But I feel it's hard to quantify isn't it? Like, would Diablo 4 beta have worked without issue had the ecosystem not already been built up to encourage people to tinker and get it working?

These kinds of intangible benefits are still positive factors I think...
