Dear all, I installed this lovely game on linux over the flatpak, which seems to work well. However, I can not find any way to change the "advanced" graphics settings. I would like to see options such as simplify the most calculation heavy options, because the game is lagging for me. However, the only option I have is to change the display mode between windowed, windowed borderless and fullscreen. From other online discussions I think that others have this option, and I do not know what to do about that.
Edit: In the settings menu called inside a skirmish, I see advanced options. However not in the main menu or in the scenarios.
