Unleashed Project Mod
The Unleashed Project Mod comes with Sonic Unleashed day stages ported from Xbox 360 version with many graphical improvements and a graphics renderer that provides graphical and stability improvements to the mod and base game.
High Resolution Shadows
- Only for the shadows casted by dynamic objects
- Works for base game and for the Unleashed Project Mod
There's a way to go beyond the shadow resolution options offered by the game, and it involves some manual modifications to the executable. Step-by-step instructions can be found here.

Issues with Nvidia Optimus laptops
Method 1: "Extend Desktop" Fix • Link
- Use Method 2 only if Method 1 does not work
- This fix is know to work on GeForce GT 555M, GeForce GT 540M, and GeForce GT 525M chipsets
Method 2: "Config File Edit" Fix • Link
Do not manually edit this file, use the configuration tool. NVIDIA GeForce GT 555M \\.\DISPLAY1 1600.900.60 1 1 1 1 0 d7b78e66-4256-11cf-fd56-b424b7c2c535 1515474505
Save the edited file. You should now be able to play the game.
One thing that should be noted is that the line "\\.\DISPLAY1" may need changing as well. In one test case, DISPLAY1 was fine when only the laptop display was enabled. However when the display was extended onto the "fake" Intel VGA display, it had to be changed to DISPLAY2. Therefore if DISPLAY1 does not work, it is recommended to try DISPLAYi where i is the number of displays you currently have enabled.
This second method was suggested by ezodagrom, and is reproduced here from a post by BlackLionPT.
Configuration Tool does not open/crashes
- Download and Install Microsoft Net Framework 4.0 from here.
- NOTE: If the above doesn't, please run Windows Update and install ALL Updates available. This way you can make sure it's not a "flaw" in your system that's causing the problem.
Black screen but can hear sound
Go to Catalyst Control Center / Nvidia Control Panel and disable all custom Anti Aliasing profiles (reset it to default if needed).
Crash on startup
Set sound quality to 24 bit, 48000 Hz (Windows Vista and newer) • Link
Other possible solutions • Link
- Complete error states
The detected configuration does not match your current hardware. Please run the configuration tool.
Delete config files and re-run config tool • Link
Crash when trying to play online ranking mode
- If you have more than 100 friends on Steam, even if you are offline in chat, online mode will cause to crash the game. Remove friends to have 99 or less, and the game won't crash anymore.
- Loading a level in the singleplayer, exiting it and then starting it in ranked mode may reduce the chances of a crash.
