Here’s a video I recorded of the issue. When the game is the active window, the bar is Green, when it’s in the background, it’s white. You can see the FPS difference and the stuttering.
If anyone can help with this, it’s be much appreciated. Since opening a support ticket did absolutely nothing.
The resolutions I’ve tried are
turning on/off Vsync, Gsync, Fullscreen, Window (every possible window resolution), messing with Nvidia settings, computer frame rate, dedicated cores(affinity), even messed with -dx12 -high launch.

Thanks in advance for anyone able to assist me.
