I recently purged windows from my previously dual booted system and installed CSGO to Manjaro from Steam. The performance drop has been significant.
I also am not able to see the names of team mates in the tab menu or over their character models in games.
I am able to play 720p at peak 30 fps with drops to 15 on opening buy menus.
I have applied DRI_PRIME=1 %command% in my launch settings
I installed Lurtis and enabled "Nvidia Prime Render Offload’. I imported CSGO and tried to run it. It just starts steam and doesnt start CSGO but in Lurtis i shows the stop button
Edit: It was a folder discrepancy with Lurtis but its working now with Lurtis, not as good performance as i had in windows but still workable. Getting around 50fps
Because DRI_PRIME=1 is for the free-driver and prime-run is the command for the proprietary driver of nvidia in hybrid mode. It can not be loaded because you use not Nouveau (the free reverse-engineered nvidia driver ), but the proprietary driver.
