Playing GTA 5 Online on Steam on Zorin

Yes, I already did exactly what you wrote As I wrote in my initial post - I tried many Proton versions and 5.0-10 was able to install and launch the launcher. I tried lower versions too, those did not get that far...

Unfortunatelly I wrote my answer to Michel into wrong topic and forum does not allow me to copy it. It is here:

How to get apps/games working comments and issues

Thank you for a tip, but... at least at the moment I was not able to get it properly installed... Perhaps the problem was, that in my PC other versions of Proton were not in that directory that your guide mentions, instead I found Proton versions in folder: ~/.var/app/com.valvesoftware.Steam/.local/share/Steam/steamapps/common Then I was not sure how to "install" it manually (simply copying extracted folder to steamapps/common had the same final result as using "protonup"), so I found some co…

Short version - I don't know how to properly install Proton version so that it would display under Steam selection...

Of course I have Nvidia driver, but... I have 470.82.00. I have upgraded the system regulary (and even the install was not that old), but last time I had to quit using Zorin exactly because I tried to switch driver version manually and then - it basically destroyed my system's networking capabilities. So I had to reinstall entire operating system... But OK, I will try to switch to:
NVIDIA driver metapackage from nvidia-driver-495

Adding later: changing Nvidia driver made it slightly worse - now it displays Rockstar launcher with Proton 5.0-10, but it does not seem to even load. Yesterday it showed loading animation.

Anyhow, I think I have to find a way how to properly install that Proton-6.21-GE-1.
