I have 5120х2160 screen, but it's too heavy on my GPU in this game. Is there a way to set 2560x1080 resolution? I tried changing the value in UserSettings.json, but it keeps resetting. And any of 1920x options looks crappy. Please help!
The best option is probably to disable the "scaling" option on your GPU, then set the resolution to what you want in-game.
That will mean that the game will draw in a smaller screenspace (not fullscreen), but even 1080p resolutions will still look crisp. The blurry effect comes from the game stretching the image to fill the whole screen.
I've not yet been able to locate where the configuration settings are located that actually affect the user-configured settings.
Thank you! I found and fiddled with that file, but none of the changes I made were reflected in-game, exactly. At the same time, when I make changes through the in-game menus, they are preserved. So that info is being stored somewhere...
