Question RTX 4080 + I7-13700k - Various Games "Hitching" - Have Tried Many Solutions - Any Ideas?

[Hypnopaedia13]

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)

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!

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?

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.

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

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!
