stutter/fps drops in games

[Guest]

Hello   I recently did a big upgrade to my system with new gpu cpu motherboard and so on. And for the most part its working great! But i have had some issues with framerate (fps) 
  I have issues where simply turning the camera can make me go from 120fps down to like 90-100 and while that doesn't sound that bad with 90+fps, its the quick "freeze" that happens during the drops that is really distracting (see video below for example). At first i thought it was my system overheating, but that doesn't seem to be the case according to HWmonitor and i also tried MSI afterburner

My specs are: NVIDIA GeForce RTX 4080
Cpu: 13th Gen Intel(R) Core(TM) i7-13700K   3.40 GHz
Ram: 32gb G.Skill Ripjaws S5 DDR5-6000 BK C30 DC
Motherboard: ASUS ROG MAXIMUS Z790 HERO
power supply: be quiet! Straight Power 12 Platinum 1200W power supply - 1200 kW - 135 mm - 80 Plus Platinum certified
And i'm using a 1440p monitor (1080p 2nd monitor)

My gpu, cpu, bios, windows and all of that is up to date.  And i even did a fresh install of windows just to make sure.

Things to note: I played through Resident evil 4 remake DLC at max settings 1440p at 120fps all the way. 

Anyway.. Here is the screenshot of HWmonitor while playing Lies of P. Max settings 1440p for about 2 hours (it did the stutter at the start of that play time too)
Maybe its the game.. Or maybe its something with my pc i just can't figure out.. Either way any ideas i can try is welcome
