Some small text but not an issue for me personally.
Steam Cloud saves are broken and won't sync despite them working fine in CM: Fortress Italy.
Works fine using the built in Pbem++ system.
The game plays great when properly set up with a custom control scheme. The engine this runs on runs notoriously poorly even on high end gaming PCs so it is best to limit the FPS to something along the lines of 30-45 FPS to get it more stable.
Steam cloud saves are broken even though Combat Mission: Fortress Italy has no such issues. It appears to be random which games in the series work and which don't.

This game used to work fine starting with Proton 8. Something has changed with the recent Nvidia OpenGl drivers (or packaging) where I can only run it with mesa/zink, but performance and playability is not really impaired on a decent system and it runs fine with this workaround.
Error: "Could not initialize OpenGL graphics. Please update your OpenGL drivers."
Doesn't work. Tried the woraround from to years ago with a custom Proton build, but it doesn't work for me. The same with GE-Proton.
If you are new with Linux - you can use my guide, how to build Proton with patch - https://github.com/Rufus111/combat-mission-linux-guide

With default Proton you will get "OpenGL driver" error

cAlphaShift patch: https://www.winehq.org/pipermail/wine-bugs/2017-May/470327.html required to launch the game itself.
Again this requires you to patch/compile Proton yourself. See this bug report https://www.winehq.org/pipermail/wine-bugs/2017-May/470327.html
Launcher works, game crashes upon launch with OpenGL error.
Error is "Could not initialize OpenGL graphics. Please update your OpenGL drivers."
Game complains (regardless of proton version) about missing language file, then crashes
Seems like it kind of wants to run. Hope it gets fixed.
Game crashes after pressing play in launcher.
With Proton 5.0 the game showed error about not being able to find language files and then displayed its launcher. Pressing play in the launcher briefly displays a black rectangle and then it crashes. Proton 4.11 crashes before displaying the language file e rror.
