Full campaign playthrough of all 4 capaigns, no crashes.
Sustains rather stable 90 FPS, not going much lower than that even in big battles, a significant improvement over Homeworld: Deserts of Kharak (80 FPS with lows of 30 FPS). Very important in this type of games as the situation changes dramatically with big armies.
with default proton versoin there are no cutscene so GE-Proton is needed for the singleplayer. solid performance when docked im getting 30+ fps
Full campaign playthrough (only act 1). All videos play. No tinkering done.
Note that campaign is very short right now, mainly multiplayer game. Tested some matches against AI, the unit unlock system seems to work as well.
Video playback is corrupt
game runs out of the box but vodeos does not play. Proton Experimental or Proton-GE also could not play the videos.
videos does not work properly

There was a long wait at the initial splash screen. Otherwise played indistinguishable from the Windows version.
Decentralized RTS netcode doesn't need any anti-cheat, so this should work fine on Linux.
