Video settings

Configuration utility general settings.

Widescreen resolution

By default, game renders at 1280x720 and then upscales the content to match selected resolution. It's possible to raise the internal resolution to 1920x1080, however most 2D assets are done for 1280x720 and thus are upscaled regardless.

Issues fixed

Run the game at screen refresh rate

Fullscreen mode defaults to 60 Hz, even if the screen refresh rate is set higher than that.

Open <path-to-game>\d3d9.ini or %USERPROFILE%\Documents\My Mods\SpecialK\Profiles\Sonic_vis.exe\SpecialK.ini depending on the installation method you used. Change TargetFPS=0.0 to TargetFPS=60.0. Change RefreshRate=-1 to RefreshRate=0.

Mouse cursor visible during gameplay

Auto-hide mouse cursor
Install Special K by following the Special K Unofficial Guide. Manual local installation may work better. Start the game and press Ctrl+⇧ Shift+← Backspace to toggle Special K's Control Panel. Expand Input Management and Mouse Cursor. Enable Hide When Not Moved and adjust Seconds Before Hiding to your liking.

4K Ultra HD Launcher Fix

If the launcher doesn't open properly on a 4K display, you will need to do some steps to fix this:

Change "SonicLaucher" Properties
Right click on "SonicLaucher" and go to properties Go to compatibility and click on "Change High DPI Settings" Check "Program DPI" box Check "High DPI Scaling Override" box Choose "Scaling Performed by: Application" Apply and its done. Now the launcher should open normally and you will be able to change the resolution (up to 3840x2160 confirmed).
