If you are on Windows would like Graviton to use higher-resolution graphics on your computer, you can do the following:
1. Right click Graviton.exe
2. Select Properties and click the Compatibility tab
3. Select the Change High DPI Settings option
4. Check “Override high DPI scaling behavior” and select Application from the dropdown menu
5. Click Apply
Note: in some cases, this may require too much memory and cause the game to crash when loading a level. If this is the case, simply go back into Properties, uncheck "Override high DPI scaling behavior," and click Apply.
