Hello Helpful Tom's Hardware Community. You folks have been super helpful so far.

I built my new rig a couple of months ago and have been playing some games and experiencing some surprising hitching.

*All games being played at 2560 x 1440

First I pulled out good ole' GTA V. Looks great, but had a variety of levels of hitching. After trying darn near every idea on the internet, I was only getting a hitch every 30-60 seconds. I tried darn near every setting in game, every setting in Nvidia control panel and a clean install of the drivers. I gave up and just played the game.

Just moved on to No Man's Sky and it near the same thing. Hitching, except every 10-45 seconds.

I may have tried the right thing but changed something else at the same time. I will take any advice and try it and will answer any reasonable question.

Thank you in advance.

Specs:

I7-13700k
MSI Suprim RTX 4080
ASUS ROG STRIX Z790-H
2x GSKILL DDR5-6000 32 GB (Each)
Boot Drive: Samsung 970 EVO Plus 500GB
Game Drive: Sabrent Rocket Q4 2TB
Monitor: Razer Raptor 27 (165 Hz) (I bought it on sale for about $350, would not have bought it for more)

And I've tested the Legacy Game Mode with GTA V, which I tried every solution I could find on. After an hour of testing, not a single hitch, buttery smooth.

Efficiency Cores were the culprit.

I swear, I always seem to find the solution after finally posting on this forum, it's like good luck for me!
Okay, so I have to test more, but I may have found a solution/the issue??

I was going into my bios to try to disable hyperthreading, just on a whim. Then I saw Legacy Game Mode, which disabled efficiency cores when Scroll Lock is on. Booted into No Mans Sky, and no hitching! More testing needed, but a good sign!

Suppose some games don't like efficiency cores / unable to distinguish and prioritise performance cores. Newer titles or titles that have been patched shouldn't be an issue.
 
Was Windows installed fresh on this system? Reusing Windows install from another system/motherboard does not usually go well.

Any utilities or monitoring software installed?

Checked temps etc?

Windows installed fresh, in fact only 2 weeks ago.

I have AIDA64, MSI Afterburner, and I use HWINFO64 to track the CPU temps. Idles at 28-35 and doesn't really go over 65

Definitely going to be testing on a few different games to see if it carries. I actually love that I can enable or disable with the Scroll Lock
