Whitelist Request

• Name of the game to be whitelisted: Alien Swarm
• Steam AppID of the game: 630

System Information

• GPU: RV710
• Driver/LLVM version: 3.0 Mesa 19.2.0
• Distro version: Ubuntu 18.04
• Link to full system information report as Gist: https://gist.github.com/kakolisgay/51a5a76a38b33d66f1f7e4dff63da1de
• Proton version: 4.11-9

I confirm:

• [x] that pressing the Play button in the Steam client is sufficient.
• [ ] that runtime config options are necessary to run the game.
• [ ] that no workarounds other than PROTON_* env variables are necessary.

Issues

• [ ] I haven't experienced any issues.
• [ ] There are no issues left open for this game.
• [x] Although I consider the gaming experience equal to Windows there are remaining issues:
  • Uncommon random lag spikes which last for one to two minutes.
  • FPS slowly lowering over time

I have not encountered #276 (Alien Swarm Freezes after clicking "Offline Practice"), Alien Swarm has been free of crashes and (game-breaking) freezes for me. Since I'm using an old machine a config was required to get acceptable fps, someone on a mid-range machine likely wouldn't need to bother with that.
