I primarily use my pc for gaming, and want to avoid upgrading to Windows 11. Beginning the journey of looking into alternatives.
I am ignorant, trying to be less so. I have a hard time understanding what exactly makes a game not work just because of OS.
Way less, even better performance than native windows in some cases
Flightless Mango used to have some good comparisons, but they’re about four years out-of-date, now. Even then, you’d expect between 10% worse and 5% better on Linux. https://flightlessmango.com/benchmarks/
Forbes article here is from this year; expect between 5% worse and 25% better when running on Linux. https://www.forbes.com/sites/jasonevangelho/2024/08/21/linux-scores-a-surprising-gaming-victory-against-windows-11/
General experience is that generally there’s no noticeable difference at all; some games that use new features might have bad performance until the new features are implemented. Last game I really had a problem with was Horizon Zero Dawn. Elden Ring had bad performance on launch day, but was fixed the next day I think.
