You might ask yourself: Why do I need this guide when Proton runs Carmageddon: Max Damage?

Well, Proton is amazing and it has done a lot for gamers running Linux systems. However, the problem with the present versions of Proton on Steam is that they are not always optimised completely. This is understandable, versions are released when they're ready. But being open sourced means that people can add tweaks to add additional compatibility and optimization.

Currently, running Carmageddon: Max Damage under the standard proton versions available in steam works, but frame rates are pretty poor. However, we can use an alternative version of proton instead! The GloriousEggroll (GE) version has many tweaks and compatibility changes which allows the game to run extremeley well. Not only that, but the GE version of Proton is also compatible with other titles on Steam, such as Mechwarrior Online, Metal Gear Solid: Ground Zeroes and Planet Zoo.

How can it be done?

The answer is: very easily!
The below steps will download and extract Proton-5.9-GE-3-ST into your Steam directory, for use with Steam titles.

Step 1:
Copy (select and press CRTL + C) and paste (middle mouse button click) this command into a terminal:


Step 2:
Restart Steam (exit completely, then start it up again).

Step 3:
From your Library, find Carmageddon: Max Damage, right click on it and select Properties.
From the options, tick the box to force a specific Proton version. From the list, pick Proton-5.9-GE-3-ST and click OK.

Step 4:
Start the game!
