Built a new PC, extremely high FPS in game, yet there are stutters/gitters during gameplay
I built a brand new, expensive PC as well as getting a 4k monitor 240hz. I am doing a minor OC a safe amount, my benchmark results are excellent and the PC is cool and healthy.
For some strange reasons in games, EVEN when settings are at the lowest, there is strange fragments on screen when I rotate the camera fast. The best way to describe it is it feels like the game is running at 30fps when my FPS display says 250+.
For this case I am playing RE4 Remake but also same stuff happening with BF6.
Things I have tried
-G-Sync turned on/off
-Bought a new ultra speed HDMI cable which works with 240hz.
-Changed hz to slightly lower than my max, and to much lower such as 180hz.
-Capped fps, and messed around with hz in game
- Used suggested optimizations for RE4, driver updates
-Checked CPU usage during gaming, all extremely low and healthy.
-Checked my monitor has 240hz enabled (it starts with 60 for whatever reason..)
If my FPS is this high why does the game feel like it's running horribly. My RTX 3080 didn't have this, why is this happening with this "monster" of a PC I just built.

My friend built this, the only thing I had a say in was GPU really which I bought second hand (tested, benchmarked) in person.
I just am extremely frustrated disheartened I put in all this work and I have no idea what is going on.
