Zero-k runs quite well on a 4k screen, but there are a few quirks.
Tips for running Zero-k on a 4k screen
Windows 10 Tips
- Disable all scaling done by windows.
- Run zerok.
- Alt-Tab out of the game.
- Open control panel(crtl-shift-esc).
- Right click on spring.exe. Click properties in the menu.
- In the menu that opens, go to the compatibility tab at the top. Click "Change High DPI settings".
- Check the override check box at the bottom. Select "application" from the drop-down.
- Zerok does not have scaling, so telling windows to let zerok scale turns it off effectively.
- In-game display
- Go to lobby setting -> graphics.
- Select in game mode as custom full screen. Set resolution to 1080x1920. Zero-k looks fine in 1080 in my opinion and it is not worth the 80% fps drop to go 4k.
- Lobby display
- Lobby -> settings -> graphics
- Menu Mode -> Windowed
- I prefer this because of easy multitasking. You can do other things on computer while waiting for a game. There is also less windows10 weirdness switching from fullscreen 1080p to a window.
- Go to Settings -> lobby
- Set scale factor to 200%-220%. This will make everything bigger so that you can actually read things without a magnifying glass.
