Let me know what I should do next, thanks.

Try setting the priority again

sudo setcap 'cap_sys_nice=eip' /usr/bin/gamescope

Ubuntu directly recommends against installing the NVidia driver from the .run file. But if the drivers from the repository aren't working, it's worth a shot.
 

1. Download the latest driver: https://www.nvidia.com/en-gb/drivers/results/200492/
2. Open a terminal in the Downloads folder.
3. Make the file executable:

   chmod +x NVIDIA*.run

    

4. Install dependencies:

   sudo apt install build-essential libglvnd-dev pkg-config dkms

    

5. Purge existing NVidia drivers

   sudo apt purge nvidia-*

    

6. Reboot
7. Once it's rebooted, rather than logging in via the login screen, do CTRL+ALT+F2 (it should say that you're in TTY2 at the top) and sign in from there.

8. cd Downloads
   sudo systemctl stop lightdm #MATE
   sudo systemctl stop gdm #Regular Ubuntu and Pop
   
   Ctrl+Alt+F2 again
   
   sudo ./NVIDIA*.run

    

9. Follow the prompts and make sure to say yes to DKMS and yes to 32-bit libraries.
10. Reboot once it completes
11. Should be able to login and try

    gamescope -f -- glxgears
