RAZER VIPER V3 PRO INPUT LAG

Hey there, I have a very weird issue with my Razer V3 Pro Mouse that is unexplainable and it's not placebo, because I tested it on multiple occasions. 

Whenever I launch a game, like CS2, Valorant or any FPS game, the mouse seems to have input lag, it drags alot and it's not very consitent 

When I ALT TAB to launch synapse while in game, the mouse completely changes it's behaivor and it runs very fast and smooth even if I remove synapse from task manager, after 10-20 minutes, it reverts to it's old slow input laggy habbit. 

I have never seen something like this ever and I change mice very frequently, I did a lot of research, but no one seems to be having the same issue as I am.

Mouse Accell in windows disabled, in-game aswell, RTX Reflex On, Bloatware removed, game bar disabled, BIOS latest, mice drivers latest etc.

The settings in Synapse for the mouse that add unnecessary things are removed, 

The mouse is directly plugged into the motherboard on the 3.2USB 

If you have any suggestions on what I should do, please let me know. Thanks!
