alt Hacker News5% would already be well within the margin of difference for separate identical clean installations of windows on the same hardware.
But the issue is that it is many multiples of that, especially on the most common PC gaming hardware (Nvidia GPUs), often more than a 25% difference in framerates. Not so important at 144fps, but very important at a 60fps baseline and for genres like fighting games.
A lot of people don't mind, say, an extra 5 frames of input delay. They don't notice it. But a lot of people do notice even an extra 2 or 3.
I do think that frame pacing issues kinda do have a critical thin threshold where it's either bearable or an unacceptable difference. And the native windows version can often already be riding right on that line. So while it's not fair to the Linux version to demand better, it is unfortunately the case that it might tip over that line.

what is the source of this non-determinism?
I'd guess that the difference only matters if you have the latest most expensive gear pushed to the limit. I have a 2019 RX5700 XT and one of the DDR4 ryzen 5 cpus and all of my games run flawlessly on Linux with great performance.
I've long since decided that buying the latest top end hardware is just spending a lot of money to be upset by buggy drivers or not being able to get 5000 fps in a benchmark but has no real gains in how fun games are.
