I am playing on a monitor with 5:4 resolution (1280x1024) but the game, as many other current games, doesn''t seem to be able to handle resolutions like this anymore. A lot of display content is cut. In other games I simply change the resolution to 1280x720 and play with black bars at the top and bottom monitor edge.
With build 0.0.9 I started the game with pressed ctrl-key, so that I could change the resolution through unity configuration but this doesn't work with build 0.0.17 anymore.
So is there any option to change the display resolution with the new build?

Try changing the resolution in the settings config file. Go to

"...\AppData\LocalLow\BoundingBoxSoftware\Prodeus\Settings"

and open GameSettings.info with a text editor. Inside change "nativeResolition" to the resolution you want and save the changes. Mabye also make the file "read only" so your changes can't be overwritten again.

I can't seem to change resolutions at all yet. Also they haven't a brightness slider yet. I just use my Radeon settings for now.

Where is the change log? Gog? Steam? Website? I have a few suggestions for them but dont know where to send them.

i guess you must go to their discord server. It is linked on their website.

If you have a Twitch account you should check out the channel of generalvivi. He's one of the devs and he often does live bugfixing and mapping streams there while also talking to people and answering questions.

it is such a painful process in-game; click-black screen-click until you finally inch your way to the desired resolution. ludicrous.
