Perfect with Proton 7.0-5 Flatpak community build.
Starts good (window mode)
Game has fixed resolution so fullscreen is not full
Played with Proton 7.0-5
As stated by a previous user, the game when initially started in fullscreen will display only about 1/4 of the game in the top left corner. Thanks for his solution:
- Proceed to ./steamapps/common/Gundemonium Recollection/" and open "gundrec.ini" in a text editor. Modify to "Resize=-1", along with "Width" and "Height" to your native resolution.
Played through a bit using a DUALSHOCK 4 without any issues.
Do NOT start the game in fullscreen mode. The game starts in a small window, but with fullscreen resolution, making only the top left corner of the picture visible. To solve this you have to delete the save-file, resetting your progress.
Workaround: In "./steamapps/common/Gundemonium Recollection/gundrec.ini" set Resize=-1 and Width and Height to your screen resolution before starting the game in windowed mode.
Tried with keyboard and xbox 360 gamepad; fullscreen and windowed mode both work; windowed mode has a fixed window size and when tiling window manager forces a different window size, the rest of the window is filled with black; 60fps
Game window in windowed mode cannot be resized. Alt-tabbing while in full-screen mode breaks the game.
