Sonic Generations is a singleplayer platform developed by Sonic Team and published by SEGA. The game was intended as a celebration of the 20th anniversary of the Sonic the Hedgehog franchise, with it featuring the play-styles and character designs of two different eras of Sonic ("Classic" and "Modern") and levels spanning the franchise from 1991 to 2010.[1]

The PC version of the game was released on November 3, 2011 on Steam, with Europe and Australia exclusively receiving a physical release. Unlike the console versions, the PC version removes the unlockable (emulated) copy of the original Sonic the Hedgehog (1991).

On September 29, 2016, all Steam users received the Casino Night DLC (an in-game pinball mini-game) for free[2].; this DLC was initially an exclusive GameStop pre-order bonus for the console versions that was later made available for purchase on Steam.

Sonic Generations features an active modding community; players have produced a variety of mods for the game’s stages, models, visual effects, audio, and animations. One such notable mod is the Unleashed Project, which ports the 9 "daytime" stages from Sonic Unleashed into the game[3] (replacing the vanilla stages).

Various mods that enhance the vanilla game are highly recommended, even for a first playthrough. These mods include HQ pre-rendered cutscenes, increased shadow resolution, and HUD upscales. See Essential Improvements and Modifications sections for more information.

Issues fixed

Issues with Nvidia Optimus laptops

Method 1: "Extend Desktop" Fix[12]
  1. Open 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 the 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: "Config File Edit" Fix[13]
Use Method 2 only if Method 1 does not work.
This fix is known to work on GeForce GT 555M, GeForce GT 540M, and GeForce GT 525M chipsets.
  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 capitalization). 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 Sonic Generations installation folder.
  6. Edit GraphicsConfig.cfg.
  7. The second line will be the name of your Intel adapter. Replace this with the name of your NVIDIA adapter 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, so you are now left with a blank line. Save the edited file. Here is a finished configuration file as an example:
Do not manually edit this file, use the configuration tool.
NVIDIA GeForce GT 555M 



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.
If DISPLAY1 does not work, it is recommended to try DISPLAYi, where i is the number of displays you currently have enabled.

Low frame rate

Lag in-game[14]
  1. Turn off in-game Vsync through the config tool.
  2. Force it through the graphics driver.

Skipping/major lag

Method 1: Game freezes at random, for a few seconds
  1. Open the Nvidia Control Panel.
  2. Go to 3D Settings, Manage 3D settings.
  3. Program settings and select "Sonic Generations".
  4. Set "Max Frame Rate" to 59.


This can be done using HedgeModManager codes, though these might not fix the issue.
Method 2: Game freezes at random, for a few seconds
  1. Turn off in-game Vsync through the config tool.
  2. Force it through the graphics driver.
  3. Download HedgeModManager and extract to the installation folder.
  4. Run HedgeModManager.
  5. Go to Codes.
  6. Check Disable FPS Limit.
  7. Click"Save and Play"


Make sure to turn off "Max Frame Rate".

Configuration Tool does not open/crashes

Config tool crashing[citation needed]


If the above doesn't work run Windows Update and install ALL Updates available.

Crash on startup

Set sound quality to 24 bit, 48000 Hz[citation needed]
Other possible solutions[citation needed]
If the sound quality fix doesn't work, try the following:
  1. Run 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 graphics card drivers, download the newest DirectX and install it, and finally run Windows Update and install all updates available.

Critical Error

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[citation needed]
  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

Instructions[citation needed]
  • 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.

Modern Sonic's Quickstep sound is missing

Various mods provide gameplay and graphical enhancements that are strongly recommended, even for a first play-through.
Users of Nvidia GPUs utilizing the Turing architecture will encounter issues with some stage mods.[15]

Mod Managers


Mod manager for all Hedgehog Engine titles. Required for all non-exe mods.
Includes more functions than SonicGMI, such as a code loader and the ability to automatically update mods.
Compatible with DLL-based mods, eliminating the need for additional modified game executables.
Some older mods have issues running in HedgeModManager. If this is the case, use SonicGMI instead.[16]
Ensure "Enable save file redirection" is checked in HedgeModManager so that the mod uses its own save file called "cpkredir.sav", instead of "sonic.sav" which is linked to the Steam Cloud. That will avoid save file progress being accidentally overwritten or lost.
Older mods may still be able to run in HedgeModManager by editing the "mod.ini" file inside mod folders. The "IncludeDir0=" code is what causes older mods to not run in HMM. When that code tries to specify a location, for example (IncludeDir0="./mods/Sonic 2006 Voice (Sonic)") it won't run because the location specifications is made to work with SonicGMI and not HMM. Changing it so it only shows (IncludeDir0=".") solves the problem and makes the older mods fully compatible with HedgeModManager.


Compatible with older mods that have difficulty running in HedgeModManager.[16]
Not compatible with mods that inject custom code into the game.

Quality of Life

HQ Prerendered cutscenes

Replaces the PC version's 480p pre-rendered cutscenes with the PlayStation 3 version's 720p ones.
Requires the "1280x720 Media Player" code to be enabled from HedgeModManager, to avoid black screens or crashes during cutscene playback.

Missing Cutscene for Casino Night DLC

Restores the missing intro cutscene for the Casino Night DLC, which was present in the console versions but absent from the PC version.
Video demo from author available here.

High-Res HUD Mod

Remasters the HUD elements for higher resolutions.

PlayStation Prompts

Replaces the Xbox controller button-prompts with their DualShock equivalents, as well as voice-clips & video files referencing the Xbox buttons.
Utilizes the official icons, voice files and video files ripped from the PlayStation 3 version of the game.

High-Resolution Shadows

A hex modification to the executable which increases the game's shadow resolution.
Only applies to shadows cast by dynamic objects, not those that are baked into the textures themselves.
May impact performance.
Included as a toggleable code in HedgeModManager.


Better FxPipeline

Adds multiple new features and fixes to the vanilla Sonic Generations renderer.
Minimal-to-no performance impact.
Features the ability to toggle between the Sonic Unleashed and Sonic Generations shader styles.
Frequently updated (as of 2021).

Soft Shadows

Requires Better FxPipeline.
Features two levels ("Soft" and "Softer").
May heavily impact performance.

Graphics Overhaul

Alternative to "Better FxPipeline". Contains considerably less improvements & features, and is not being worked on anymore.
The game renders generic shadows at 90° angles; this mod enables true directional shadows and light shafts, among additional graphical tweaks.
Minimal-to-no performance impact.
Also includes a version for the "Unleashed Project".
Lighting is inconsistent, with some areas making Sonic appear far too dark (e.g. Chemical Plant: Act 2).
Hub world is given an emanating, bright glow (straying from the original style).


Unleashed Project

Ports the 9 "daytime" stages from Sonic Unleashed into the game, replacing the original Generations stages.
Features graphical and gameplay tweaks, as well as a custom hub-world.
Does not work out-of-the-box on NVIDIA Turing GPUs. However a workaround has fixed this.
