Assuming this is the usual case where most games are within noise of each other, the ones that don’t run under linux are excluded, and nobody acknowledges that the need to precache/predownload shaders provides short term benefits.
Its like people miss the good old days of “This is the year of linux gaming. Everything works and is perfect. Okay, those games don’t work. But every game I care about works. Except the ones that don’t”. Like, we really are in a golden age of gaming parity but pretending there isn’t still work to be done serves no benefit.
