I had a faulty motherboard that wouldn't accept a newer bios update that was any newer than Aug 2021 without insta BSOD/shutting the pc off before the w10 login screen, or insta crashing/freezing the entire pc once the desktop loaded....bought a new b450 asus mobo and it accepted the new bios, although was still doing the random stuttering fps drop lagging crap in games...pulled CMOS, then it seemed to work and games have been better. Didn't really feel like spending a ton on a motherboard when am4 is EOL anyway
One thing that sucks is, my fps is about 30-40fps lower testing Fortnite, although, they did just have a total new map overhaul and season come out so it could very well be less optimized, I'm really unsure. It sucks not knowing 100% if it's an unoptimized game or if something is wrong elsewhere. Before, I was getting ~120-130fps on 1440p mostly epic settings with shadows set to high, except with the horrible random stuttering that was driving me mad since my 3700x, 32gb ram, and 3070 gaming pc is more than good enough for high refresh 1440p gaming. I did extensive testing for a long time testing different stuff out until Asus customer support told me about the Ryzen fTPM problem going around that I didn't even know about. I consider myself a techie compared to most people, but, don't really keep up with every little news story every day.
I'm assuming some w10 update messed with the fTPM stuff that started all this crap, since, games didn't used to stutter and lag. I'm not on w11, and don't plan on being on it begrudgingly until w10 support ends, have heard and read wayyyyy too many bad things about 11 to want to deal with that headache until a few more years have passed for them to iron out the problems. Weird that it only affected Ryzens apparently. If the new mobo and bios didn't fix stuff I was ready in a heartbeat to switch to a i5 12400 6 core 12 thread 12th gen intel, I never ended up streaming like I thought I would so the 3700x threads didn't really help me much. I'd wager even a 10th gen 6c/12t i5 would be fine for this whole PS5/Xbox Series X|S console gen. Streaming encoding can be offloaded to the gpu these days anyway too. Words truly cannot describe how much frustration and trouble this stuttering crap caused me. It really sucked not having a 2nd pc to test stuff on and troubleshoot. I guess I took having a modern (at the time) ddr3 secondary system in years prior for granted. I've now acquired enough parts to Frankenstein together a modern ddr4 secondary system.
Here's to hoping some other windows update doesn't mess something else up causing horrible stuttering despite strong pc specs. I sure miss the days of stone cold reliable set it and forget it Sandy/Ivy bridge on w7.
