To be fair, if you game, and particularly if you game with relatively new, AAA titles, you should not be using an Insiders Preview build.
To be even more fair, if you game and want the absolute best performance - go back to Windows 10.
I use Win11 as my daily driver, and I game on it (from Skull and Bones, Diablo IV, Cyberpunk 2077, Fallout 4, Forza Motorsport, and other intensive titles (Elden Ring, Everspace 2, Ghostwire Tokyo, etc.) and I get decent enough performance from my rig to not complain too much - but report after report after report shows that Win10 still outperforms Win11 in apples to apples comparisons - IOW, the same exact rig, tested alternately running Win10 and Win11.
Others here have already addressed 24H2 directly.
