Portal: Revolution, from the start, has included a native Linux build. As some players have recently reported, it was broken because of recent Steam updates. To fix this we have decided to remove the native Linux binaries in favour of Proton. Don't panic.

Our native Linux build sucked. You may have experienced frequent hangs and stutters related to gel rendering or other strange bugs. This stems from a bug in our multithreaded rendering code for gel blobs, and despite our best efforts we were not able to fix it. To make matters worse, it only happens on the native Linux build. Windows and Proton are not affected.

Because of these two reasons we'll ditch the native build and run the game through Proton. Performance should be comparable, if not even better at times and stability is definitely improved. This change shouldn't affect your gameplay in any way, but if you experience issues, please feel free to report them to our support email [email protected] AFTER you have tried these troubleshooting steps:

These issues would normally not occur on a fresh launch but removing a native Linux build might catch Steam off guard. Here's some troubleshooting steps for issues we've encountered so far

Try restarting Steam or Verifying integrity of game files. If that doesn't help, set the game to use Proton version 9 (Or whichever works for you) in the Compatibility settings. Check the file path manually to see if that exe file exists.

There might be some points during the transition, but I hope we can smooth it all out in time. I wanted to post this update early while we're still ironing out some kinks.
