Project Demigod – Fix Linux Crashes Using Proton

This game is enjoyable, very enjoyable. Ahora, why should we, the Linux Losers, not have the chance to experience it too? En esta guía, I’ll show you how to solve the problem of Unity crashing instantly and also how to open the game, with the hope of getting you started without any problems.

Unity Instant Crash Fix

When you download and try to run this game, you might face an instant crash. This happens because Unity has shifted from OpenVR to OpenXR in their engine. Afortunadamente, the solution is quite simple.

1. Open a terminal.
2. In your package manager, install ‘openxr’.
   • For Arch: sudo pacman -S openxr
3. También, install the following packages: lib32-gtk2, lib32-libva, lib32-libvdpau. tenga en cuenta, these are the names in pacman, yours may differ.
   • For Arch: sudo pacman -S lib32-gtk2 lib32-libva lib32-libvdpau

If you’re having trouble finding the libraries, do a search on the internet for: [your_distro] [paste_library_here]

Por ejemplo: ubuntu lib32-libva library

Now that it’s done, I suggest rebooting your system; sin embargo, it can work fine without doing so.

Changing Proton Version

Now that OpenXR is installed, let’s adjust the Proton version the game is using. If the game and HMD (Head-Mounted Display) have the wrong Proton version, they won’t communicate properly.

The version that worked for me, and the one I suggest, is Proton 7.0-6. If this version doesn’t work for you, try switching to 5.13-6 o 5.0-10. If none of these work, you can attempt 6.3-8, although I don’t recommend this one as it had a strange issue where everything seemed like I was looking at it with my eyes crossed, causing a headache.

If you know how to change your Proton version, please move on to the next section!

Changing the Proton version is easy. Así es como:

1. Go to your Steam library and locate ‘Project Demigod.’
2. Right-click on it and choose ‘Properties.’
3. Navigate to the ‘Compatibility’ tab and check the box that says «Forzar el uso de una herramienta específica de compatibilidad de juego de vapor.»
4. In the drop-down menu, select the Proton version you want. En este caso, let’s choose Proton 7.0-6.
5. Click the X button, y ya terminaste.

Starting The Game

Quick note about starting the game: While some can click play and everything works, most people need to open SteamVR first and then launch the game from there. You can do this either in the VR Interface or directly through the Library.

Importante: Do not use the launch option «-openvr» as it causes issues for most people I’ve tested with!

Still Broken?

If the game is still not working for you, no te preocupes. Linux can be tricky, and solutions aren’t always straightforward. If you’re facing issues, please leave a comment below, and I’ll do my best to assist you. These are solutions I discovered through trial and error over a few hours.

Before leaving a comment, try a few things:

• Verify the integrity of game files. It’s an obvious step, but it has saved me from multiple problems in the past.
• Experiment with other Proton versions. Even though I’ve listed a few above, they might not work for you. I recommend trying any version below Proton 5.0-10.
• Run the game without a VR Headset plugged in. This is to test if the issue is related to the HMD side of things or something with your PC in general.

If the game still doesn’t work, deja un comentario. También, let me know if the game runs fine without a VR Headset connected to the PC. This information can help me guide you toward finding the correct solution for your situation.
