Essential improvements[edit]

Unleashed Project Mod[edit]

The Unleashed Project Mod comes with Sonic Unleashed day stages ported from the 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[edit]

Information Only for the shadows cast by dynamic objects
Information 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 fixed[edit]

Issues with Nvidia Optimus laptops[edit]

Method 1[edit]

Fix Method 1: "Extend Desktop" Fix

  1. Open up Nvidia Control Panel.
  2. Click on "Manage 3D Settings" in the left side of the panel, and click "add".
  3. Select <path-to-game>\SonicGenerations.exe.
  4. Select the option to force it to use Nvidia Graphics Card.
  5. Now, go to your desktop. Right click on it, and select "Screen Resolution". Press Detect in this new Window. (If you can see two displays that are grayed out and named after your video cards, you're probably good to go.)
  6. Choose your Nvidia card and select "Attempt to connect anyway on [VGA/HDMI]". When you found it, click apply.
  7. Choose extended desktop and apply again. This will force-activate your discrete GPU.
  8. Open the Sonic Config tool and see if your Nvidia card is present (it really should be), and of course, choose it. Now start Sonic, and it will probably work.
  9. If not, try running the Sonic Config again and this time deliberately select the non-Nvidia card. Try starting Sonic again. Some people have said that the now-force-activated Nvidia card took control anyway at this point, solving the problem.

Method 2[edit]

Information Use Method 2 only if Method 1 does not work
Information This fix is know to work on GeForce GT 555M, GeForce GT 540M, and GeForce GT 525M chipsets

Fix Method 2: "Config File Edit" Fix

  1. (Revert any changes you made in Method 1, if necessary: alter the Screen Resolution settings to Show Desktop Only on 1, Apply, then pick Remove This Display on the NVIDIA screen, and Apply again).
  2. Open the NVIDIA Control Panel, go to "Manage 3D Settings" then "Program Settings". Add the sonicgenerations.exe executable and set the preferred graphics processor to be the NVIDIA one.
  3. Open "Control Panel" and look for the "Device Manager". Open it and expand the "Display Adapters" item. Make a note of the exact name given to your NVIDIA adapter (including the use of capitalisation). There may be trailing spaces - to be sure you have the whole name, open the adapter's properties in the same menu, switch to the Details tab, select "Device Description" from the drop-down, and right-click copy the displayed information.
  4. Use the Sonic Generations configuration tool to configure the game to your liking and save.
  5. Go to the Sonic Generations installatio folder
  6. Edit GraphicsConfig.cfg.
  7. You should notice that the second line will be the name of your Intel adapter. Replace this with the name of your NVIDIA adapter exactly as it appeared in Device Manager.
  8. You should see a line that says something like "MONITOR\LGD0292\{4d36e96e-e325-11ce-bfc1-08002be10318}\ 0000" (this will vary depending on your exact setup, just look for line of this format), it should be the second to last line. Delete the contents of this line completely so you are left with a blank line. Here is a finished configuration file as an example:
Do not manually edit this file, use the configuration tool.
NVIDIA GeForce GT 555M 


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.

Information REMINDER: It is crucial that when you go to device manager you copy it exactly as it says. The tested GTX 580M was followed by 5 spaces; the tested 540M and 525M by 2. Your own chip's details may vary.

This second method was suggested by ezodagrom, and is reproduced here from a post by BlackLionPT.

Configuration Tool does not open/crashes[edit]

  1. Download and install the Microsoft .NET Framework 4.
  2. 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[edit]

Go to Catalyst Control Center / Nvidia Control Panel and disable all custom Anti Aliasing profiles (reset it to default if needed).

Crash on startup[edit]

Fix Set sound quality to 24 bit, 48000 Hz

See Sound problems (cracking, delays, missing music/effects, etc.)

Fix Other possible solutions

Information If the sound quality fix doesn't work, try the following:
  1. Try running Sonic Generations and Steam as administrator.
  2. Have Steam verify the integrity of the game cache
  3. If you still have a crash after doing the above, update your graphic card drivers, download the newest Direct X and install it, and finally run Windows Update and install all updates available.

Critical Error[edit]

Information Complete error states The detected configuration does not match your current hardware. Please run the configuration tool.

Fix Delete config files and re-run config tool

  1. Delete *.cfg files in <path-to-game>
  2. Re-run config tool and ensure you select resolution and refresh rate that your computer supports.

Crash when trying to play online ranking mode[edit]

Fix Instructions

  • 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.
