Withoug framerame limit, the game was running too fast.
Works perfectly out of the box. No launch options required.
The game would launch but only with a black screen without the use D9VK launch flag
Game works perfectly with "PROTON_USE_D9VK=1 %command%". Without D9VK the re is no video, just a black screen.
With Proton 4.2-3 there is no video unless you use launch option "PROTON_USE_WINED3D11=1 %command%". But then the game has much worse performance. Forcing older Proton 3.16-9 the game is flawless out of the box and works without any launch options (it does not even have the music stops playing after resume problem as mentioned previously).
The game runs too slowly to be playable.
Music doesn't resume after pause
Out of the box. No input lag.
Freezes at the title screen of any game
The music does not resume playing after you have paused the game.
