Maybe old news but might help controller players. I was getting massive frame drops with my new 3090 FE, Stuttering and FPS would not go over 133fps in 90% of games Biomutant, Call of Duty Modern Warfare, State of Decay 2, Cyberpunk 2077 + Others. After days of testing, I found out that it was my official Xbox One BluTooth Controller. Once I disabled the Bluetooth and used a USB cable all games running great now. 165fps no Frame drops of stuttering.
