I would use Heroic Games Launcher personally. You can add any game you want, and before it creates the prefix for you, you have the option of running installers on the prefix first. Then you can add the game executable. If the game requires proton fixes which it very likely would, you can search the game on SteamDB to find the AppID then make sure there’s a file called steam_appid.txt next to the game executable with the game’s app ID from SteamDB. That will tell Proton to apply any fixes that it has on file automatically.

If you’re a fairly advanced user, you can also just look at what files are included on the game’s SteamDB “Depots” page. For example, GTA San Andreas looks like it requires “DirectX Jun 2010 Redist”. You can either download that from Microsoft or you can run winetricks (through Heroic, or through terminal) on the prefix to add d3dx9.

Steam DB: https://steamdb.info/

First of all, make sure that Steamworks Common Redistributables is installed because according to the steamdb page for GTA 5 it requires vcrun2022 and d3dx9 installed from winetricks (or protontricks) which it normally gets from the Steamworks Common Redistributables automatically.

From my admittedly very brief research, it doesn’t look like you can play GTA 5 online if you skip the launcher but if you want to just play offline you can set your Steam Launch Options by right clicking the game and going to properties. If you set it to %command% -scOfflineOnly that will skip the launcher but disable multiplayer.

You can also try setting the Steam Launch Options to PROTON_USE_WINED3D=1 %command% which forces Proton to use the OpenGL driver rather than the Vulkan driver for D3D.

I’ve tried both pretty extensively and moonlight is so, so much better. I was really surprised, but it’s far and away better than steam link. You can stream your PC by using Sunlight - https://github.com/LizardByte/Sunshine

Ezarr is a pretty great little project for getting started. Just clone the repo and follow the README and it should just be plug and play.

Yeah, either put quotes around it ‘/like this/you can incorporate/spaces/into your paths’ or /just\ escape/your\ spaces/like\ this

lol weird! Maybe something got updated.

Can you run the game from the terminal so you can see any error messages that are popping up? To do that, exit steam and run steam steam://rungamebyid/1817230

I’m assuming you’re talking about this game which has an App ID of 1817230. If it’s a different version of that game, find it on steamdb and use the App ID from the correct game.

I think if you’re coming from Windows, the closest thing to a Windows experience imo is Ubuntu. You can opt in to pre-release updates which is good for gaming as others have said. Also, basically everything can be done via GUI in Ubuntu while you learn to get comfortable with the terminal.

Using WINE or Proton should work then you can use winetricks or protontricks to install the specific component you need if the game doesn’t already install it.

Are you on a laptop using hybrid graphics by chance? Switching to dedicated graphics might help in that case.

Add PROTON_DUMP_DEBUG_COMMANDS=1 %command% to the Launch Options in the Properties menu of the game. Launch the game once and then check in /tmp/proton_(your username). There should be bash scripts for running the game in there. Close the game in Steam and launch the game using the ./run command and see what errors come up.
