developed by Valve, allows Linux users to run Windows-based games on Steam. However, some games, like Apex Legends, face compatibility challenges, especially with GE-Proton (GloriousEggroll’s custom Proton build). Many Linux gamers have reported errors and performance issues when trying to launch or play the game.
In this article, we will explore the GE-Proton issue with Apex Legends, its causes, and practical solutions to ensure a smoother gaming experience on Linux.

Why Apex Legends Struggles with GE-Proton
Apex Legends has an advanced anti-cheat system called Easy Anti-Cheat (EAC), which often blocks Proton users. This security measure prevents Linux gamers from connecting to online servers, making the game unplayable.
Additionally, updates to Apex Legends or Proton can break compatibility. Many users report issues after game patches, causing crashes, black screens, or failed launches. This ongoing conflict between Proton and EAC is a major roadblock.
Common GE-Proton Issues with Apex Legends
1. Game Not Launching
Some players encounter a situation where Apex Legends refuses to start. Clicking ‘Play’ does nothing, or the game crashes before reaching the main menu.
Fix:
- Make sure Steam Play is enabled in Steam > Settings > Steam Play.
- Select the latest GE-Proton version from Steam > Properties > Compatibility.
- Verify the game files via Steam to ensure no corrupted data.
2. Easy Anti-Cheat Kicking Players
Even if the game launches, some players get disconnected due to EAC restrictions. This happens because Apex Legends' servers block Proton users.
Fix:
- Ensure your EAC Runtime is correctly installed.
- Run the game with the launch option: Protonge,
EAC_RUNTIME=1 %command%
. - Try switching between different Proton versions to see which works best.
3. FPS Drops and Stuttering
Performance issues like frame drops and input lag can ruin the gaming experience. These issues are common when using Proton to run graphics-intensive games.
Fix:
- Enable Gamemode (
gamemoderun %command%
) to optimize CPU and GPU performance. - Use MangoHud to monitor and adjust graphics settings.
- Lower in-game settings to reduce strain on your system.
Alternative Solutions to Play Apex Legends on Linux
If GE-Proton doesn’t work, some alternatives may help. One option is trying Proton Experimental, which receives frequent updates from Valve to improve compatibility.
Another method is using Lutris, a Linux gaming tool that provides additional tweaks for running Windows games. Some users have reported better results when configuring Wine + DXVK manually.
Conclusion
Running Apex Legends on Linux with GE-Proton remains a challenge due to EAC restrictions and performance issues. While there are workarounds, they may not always be reliable after game updates.
For the best experience, stay updated with ProtonDB and Linux gaming communities. They provide real-time solutions whenever Apex Legends compatibility changes.
