Check out Wendell, Zen 5 Gaming: Where’s my 5%. Windows vs Patch Windows.
He gives a non-partisan, non-tribal, non-judgemental assessment of windows 11 current against windows 11 insider agains linux. It’s a 40 minute video so those with short attention spans may not watch it through.
He also states that he doesn’t know why… watch it then say windows can’t be better. (Hint, win 11 insider build shows some improvements)
To be fair to Microsoft, they write an operating system for a huge number of motherboards, processors, GPUs, memory, keyboard, mice, sound devices, miscellaneous display programmes, RGB, fan control, monitor control etc etc. There isn’t a standard PC. With that I can understand (not necessarily agree with) Microsoft culling support for older CPUs, using TPM gave them the premise to do so. Windows code base is built on the ancient(?) original NT stuff, iterated, some parts culled, some parts extended, some parts new. Multicore wasn’t a thing at initial design, Win 2000 advanced server was only 4 core and for the main part only exotic workstations had dual core. Athlon x2, pentium 4D really weren’t used well, things got better as you can see improvements in throughput (to a limit) as cores increase but it is limited.
I can’t speak for Linux.. watch Wendell’s video. It looks better in some games, worse in others BUT it doesn’t require the cludges Windows demands to make the scheduling system work.
