It's also quite nice to actually hit 165 fps in some less demanding games on my 165 hz monitor.
I've personally never found Ray Tracing to be worth the performance impact. I have a 3090 and a 7900 XT at home, on different computers. When opening a new game, I just keep everything on Medium, turn RT off if possible, and enjoy good fps at 4K in most games.
Doom The Dark Ages was the only one that didn't perform as well as I'd like. Still, perfectly playable at 1080p, Medium settings, targeting 120+ fps.
You really need to get your eyes checked.
When I was trying to upgrade to Windows 11 from Windows 10 I got the same warning. It is the reason why I'm now happily running Xubuntu on the same machine.
I did end up installing a Windows 11 VM (VirtualBox) which works perfectly fine running as a guest under Xubuntu on a 4790k (screw you Microsoft). But I otherwise never want go back to Windows as a daily driver. The enshittification just got too much for me.
AI bros are building something fantastic, but let's not forget that value isn't necessarily brought by sheer prices
