Windows 10. I got a Ryzen 5900x that works fine on an old bios version. Upgrading to windows 11 requires me to upgrade the bios or get tTPM stutters. However, the new bios versions reduce the (single core) performance...So I'm sticking with windows 10 for now. I have windows 11 on my laptop and don't mind it. Tried Linux multiple times over the past 15 years, but it always kills itself within weeks. As a server it works well though.
I'm on a 5800 series and sometimes my mouse gets extremely stuttery. I'm on windows still because I'm lazy and I haven't wanted to put in the effort to switch. Could this be causing the stutters?
Sounds like it I think. From what I've read they are stutters for like a second every once in a while (don't know if it's every few minutes, every half hour or less). The latest bios version of your motherboard should fix it.
