Changed the renderer_type to "DirectX12" in this file: /SteamLibrary/steamapps/compatdata/2694490/pfx/drive_c/users/steamuser/Documents/My Games/Path of Exile 2/poe2_production_Config.ini

I think this is mainly an issue with Nvidia and Vulcan for this game in particular. Some people have reported success using gamescope to launch in with Vulcan and using that or changing the renderer to DirectX that way.

Game played great some stutters occaisonally but it's just really poorly optimized in general.

Once I changed the game to DirectX it worked great, honestly similar performance to what I was getting on windows, no graphical errors or crashes whatsoever.
