-dx11
Without adding -dx11, some areas will crash the game. Otherwise runs smoothly as long as you do that.

Works out of the box
Works great out of the box, i've been also been able to reed Discord's reward. The initial cutscene showed up just fine

frame limit to 30fps
the default txt size is readable but i maxed it out just to make it easier.
played with a friendd for a few hours

Missing cutscene textures
During cutscenes, FPS goes down to 10
During first cutscene, a missing texture appears.
Apart from cutscenes, game seems to work fine. Haven't tested on steam deck, but heard that support for steam deck will come later. (source: https://towerborne.zendesk.com/hc/en-us/articles/30107629264141-Does-Towerborne-work-on-Steam-Deck)

Cutscenes do not play video, only audio. Tried Proton-GE-8.x, no dice. Tried mf-install, no dice.
Proton 9, Proton GE 9, and Proton Experimental all result in a crash shortly after getting to the main menu. But going back to Proton 8 seems to make the game run just fine.
I just wish I could get the cutscenes to play.
