screensharing makes games unplayable

Hi, I have an Artix dinit system running KDE plasma wayland on an AMD cpu and Nvidia gpu.
Whenever I try to screenshare a game, whether it be through one of the discord clients that support wayland screensharing like vesktop, or screensharing through firefox using discord on web, the game I screenshare becomes completely unplayable. Screensharing will cause the game to stutter like crazy, for every ~0.3 seconds of it running fine it will freeze for around ~1-2 seconds. I have noticed that for some reason this only happens if the game is the focused application and is running in fullscreen. If I continue to screenshare and simply alt-tab to focus on a different window, the game stops stuttering. If I make the game windowed, it stops stuttering. If I run the game under gamescope, it stops stuttering. I really have no clue what could be causing this, any help would be appreciated!

could you provide some more basic info? what gpu? driver version? kernel version and params? pure gayland or xgayland app? do you have nvidia modules preloaded?
cat /etc/modprobe.d/nvidia.conf (or at least a file that modifies nvidia NVReg parameters) vs cat /proc/driver/nvidia/params?

My gpu is the 4080, on driver nvidia-open-dkms version 565.57.01-1

kernel is 6.11.7-artix1-1 with parameters of
Code: [Select]
BOOT_IMAGE=/boot/vmlinuz-linux root=UUID=e7fd22c2-4c03-492f-8f1b-f7db6fce0506 rw net.ifnames=0 quiet amd_iommu=on iommu=pt nvidia-drm.modeset=1 nvidia-drm.fbdev=1

application doing the screensharing is native wayland and application being screenshared I would assume is running under xwayland, thats the standard for basically every game isn't it?

I have this in my /etc/mkinitcpio.conf to preload the nvidia stuff
Code: [Select]
MODULES=(nvidia nvidia_modeset nvidia_uvm nvidia_drm)
