The game defaults to the desktop resolution on first launch. Accessing the options menu enforces its 16:9 and 16:10 resolutions.
Use the community patcher to remove the maximum resolution limit
  • After patching, select the highest available resolution above native to have the game set to native.[5]
(e.g. selecting 3840x2160 at 3440x1440 will have the game set to 3440x1440 without it being reflected in the listed resolution)
Results in Hor+ scaling and Vert- behavior from letterboxing. The letterboxing can be removed with a mod.
Prevents the game from enforcing its hardcoded resolutions upon menu access.
Mouse pointer is always confined to 16:9, forcing to use other input devices to navigate the main menu at 48:9 resolutions.[6]
Set any width and height through the config[7]
  1. Launch the game and set its options as preferred, then quit.
  2. Go to the configuration file(s) location.
  3. Locate the lines that start with Screenmanager Resolution Height and Screenmanager Resolution Width.
  4. Double-click one, select Decimal and enter the desired height or width, then click OK. Repeat the step for the other.
  5. Run the game and avoid accessing the options or the pause menu (Esc).
Results in Hor+ scaling and Vert- behavior from letterboxing.[8] The letterboxing can be removed with a mod.
Mouse pointer is always confined to 16:9, forcing to use other input devices to navigate the main menu at 48:9 resolutions.[6]

  1. 1.0 1.1 File/folder structure within this directory reflects the path(s) listed for Windows and/or Steam game data (use Wine regedit to access Windows registry paths). Games with Steam Cloud support may store data in ~/.steam/steam/userdata/<user-id>/906100/ in addition to or instead of this directory. The app ID (906100) may differ in some cases. Treat backslashes as forward slashes. See the glossary page for details.
  2. For example, ← Backspace is not listed among the Controls but used to back out of objects inspection; R for Response is not documented; some of the functionality of Space is remappable but even when fully remapped, the game will require its use to close the SamOS interface.


  1. Verified by User:Rose on 2019-05-21
    Closed the launcher, removed its folders and launched the game without issues.
  2. Verified by User:Rose on 2019-05-21
    Used a custom desktop resolution of 3840x2160, got to select it in the menu, and it lowered the FPS.
  3. Verified by User:Rose on 2019-05-21
    Found this out by extracting the game files.
  4. Verified by User:Rose on 2020-05-24
    Tested at 65 Hz and 75 Hz, reaching 75 FPS at the latter. Disabling Vsync had no effect.
  5. Observation letterboxing remover - last accessed on 2020-05-23
  6. 6.0 6.1 Verified by User:Rose on 2019-05-21
    Screenshots taken at 5760x1080, 3840x1080 (both custom), 2560x1080 and 1920x1080, then compared.
  7. Verified by User:Rose on 2020-08-13
  8. Verified by User:Rose on 2019-05-23
    Played through the game at 2560x1080 without notable issues.
  9. Verified by User:Rose on 2019-05-24
    Quickly moving the mouse resulted in little change on the screen, while moving it slower resulted in much more distance traveled.
  10. Terrible mouse smoothing - last accessed on 2020-05-22
  11. 11.0 11.1 11.2 Verified by User:Rose on 2019-05-23
    Tested with an Xbox 360 Razer Onza controller.
  12. Verified by User:Rose on 2019-05-23
    At 2560x1080, the SamOS hints are partially cut off but visible. At 5760x1080 there are no signs of them.
  13. Verified by User:Rose on 2019-05-21
    It works, and it seems to be the only way to access the extra keybindings.
