Before you ask for PC specs, I'm gonna point it out so you can make sure that it is not the problem with specs 100%

RTX 4080S

R9 7950X3D

32GB DDR5

RGB works flawless whatever I'm doing on PC. (As title says BlackWidow V4 Pro)

But as soon as I open any game, lights on RGB start flickering like it's running on 0.5 frames per second. I tried multiple RGB modes and with any mode it's the same story. When I exit to desktop while game is working in background RGB is back to normal. It's only when I am in-game screen.

I checked a few fixes on internet but nothing really helps.
