hi,
I installed zorin a couple of days ago,I managed to solve some issues on my own but this one i cant do myself. I have installed Steam & Lutris to try some gaming performance, but i noticed they were all running slower than expected. I suspected that maybe my GPU was not working. When I checked the hardware specs it said I was using
NVIDIA Corporation / Mesa Intel® UHD Graphics (TGL GT1) which i have no idea what it means, but it is not a NVIDIA GeForce RTX 3050 Ti
Try this Gnome extension. It let you switch between the intel and nvidia driver. But you need to have nvidia-prime driver installed. Check additional driver to see if Nvidia driver is installed.
