rtx3080 High end build underperforming

[Raniah]

Alright I’ve already brought this matter to your attention once before and I took it to the workshop afterwards and they couldn’t identify the source of the problem so I’m here once again desperate for some answers, my gaming pc with RTX3080 graphics card and ryzen7 3800x cpu is underperforming. 
the issue is that its not constant across all games, for instance on games like Witcher and apex I get around the same performance as the benchmarks while for others like rainbow6 and warzone for instance i get a much lower performance, and the weirdest part is that the performance doesn’t improve no matter how much I tweak the game settings or the resolution i could be playing on ultra everything 2k and get the same performance on low everything 720p, it’s bizarre and no one can tell me what the problem is! 
Vsync isn’t on and the frame rates aren’t the same for all games, but the one thing they have in common is that they all work as if they’re on highest settings regardless of what settings they’re on, for example I cant get cyberpunk to run any higher than 60 fps while I get frame-drops down to as low as 20....please help its driving me insane.

What's your GPU and CPU utilization like when this is occurring? What are your temps on both? No Vsync, but do you have G-sync/FreeSync active? What's the refresh rate of your monitor?

Monitor’s 165 and none of those r active no, gpu varies its at 70% in games like rainbow and warzone fr instance but up to 99 in others, cpu goes between 40-70% n temps r never above the 70s fr both
