Performance Iss with new Rig for League of Legends

My Configuration; https://www.digitalstorm.com/configurator.asp?id=3584814

I'm currently having some stuttering issues with League of Legends. I'm not entirely sure why it happens specifically with this game (my other games don't seem to be affected) but I could have a good 400 FPS+ at the start of the game, then mid-way through the game around 260-ish, then it drops to 60 (stutters) and then immediately ramps back up to the 230+ range.

The issue here is the stutter because it lasts for about a full second but you know in games like this that means death. I'm trying to figure out why my 3k+ PC is having issues with this game where as my older PC that uses a 980 TI has no problems with league.

I am using Gsync and a Gsync compatible monitor 144 HZ from LG. Not sure if that matters. Either ways, not sure if anyone has some tips to improve the performance to reduce the amount of these micro stutters.

Thus far I have tried the following;

-Changed the Nvidia card's Power Management mode to 'Prefer maximum performance'.
-Updated drivers for 3080 Graphics card to most up to date (461.40).
-Capping my league's FPS to 144.
-Removing the 144 FPS Cap to Uncapped.
-Enabling V-Sync and capping to 144.
