120+ FPS
Gameplay is capped at 60 FPS. There are two cappers in place.

To remove the internal cap, hex edit SonicGenerations.exe (a fixed .exe may be need first, which can be obtained from WSGF attachment), and replace both instances of 89 88 88 3C with 2F 8E E3 3B (144 FPS) or 3F 0B 36 3B (360 FPS). As for the external cap (this needs to be done with every launch), open Cheat Engine while the hex edited .exe is running and search for 0.01666666666 as a float in rounded (extreme) mode while "Executable", "Writable" and "CopyOnWrite" is set to "Don't Care". Select the first value brought up (should be 0019FD34), right click and the select "Find out what writes to this value" which opens up a debugger. Continue running the game for a few moments and then select the assembly code presented in the debugger and click "Disassembler". Click on the Opcode and replace it with "nop" (without the quotation marks). Select 'Yes' on the warning screen. Go back to the selected value in Cheat Engine (0019FD34) and replace it's value with 0.00694444 (144 FPS) or 0.00277777 (360 FPS). This will cause Sonic's jump height to be reduced and he will be unable to move while standing still, making Classic Sonic's stages impossible and Modern Sonic's stages slightly harder to complete (some stages require differnet pathes to be taken). These issues should be solved with some physics-altering mods.

Cutscenes are either pre-rendered or capped at 30 FPS. The in-engine cut-scenes can be played at higher rates (this needs to be done with every launch). open Cheat Engine while the hex edited .exe is running and search for 0.033333333333 as a float in rounded (extreme) mode while "Executable", "Writable" and "CopyOnWrite" is set to "Don't Care". Select all values then replace them with 0.00694444 (144 FPS) or 0.00277777 (360 FPS). These values are seemingly randomly generated and change with every launch. This will make some mouth animations to be completely out sync wile others are fine. This may be the results of other unnecessary values being changed which can be resolved by check each value every time.
High dynamic range display (HDR)


Force windowed through DxWnd[citation needed]
  1. Download and run DxWnd. (v2.04.62 is confirmed to work.)
  2. Click on Edit, then Add.
  3. Set the Path to <path-to-game>\SonicGenerations.exe.
  4. Set the window position and size.
  5. Set Desktop for borderless fullscreen windowed.
  6. Click on Input tab, set Cursor visibility to Hide.
  7. Click OK, then File and Save.


Newer versions of DxWnd (tested with v2.05.14) do not work. The game refuses to start, saying the hardware doesn't match the configuration.
Force windowed through Direct3D 9 Ex (Optimized Renderer) mod
  1. Download HedgeModManager and extract to the installation folder.
  2. Download Direct3D 9 Ex (Optimized Renderer) and extract Direct3D 9 Ex (Optimized Renderer) folder to <path-to-game>\mods\.

  1. Install Flawless Widescreen.
  2. Run it and install the Sonic Generations plugin.
  3. Go to the Flawless Widescreen installation folder.
  4. Go into the \PluginCache\FWS_Plugins\Modules\SonicGenerations\Dependencies\Scripts\ folder.

Issues fixed[edit]

Issues with Nvidia Optimus laptops[edit]

Method 1: "Extend Desktop" Fix[citation needed]
  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[3]
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 FPS[edit]

Lag in-game[3]
  1. Turn off in-game Vsync through the config tool.
  2. Force it through the graphics driver.

Configuration Tool does not open/crashes[edit]

Config tool crashing[citation needed]


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

Crash on startup[edit]

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[edit]

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[edit]

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.

Quickstep fix[edit]

Modern Sonic's Quickstep sound doesn't play[citation needed]
  1. Download this fix.
  2. Place the contents of "normal" map into <path-to-game>\


Replace Unleashed Project's files with the fixed files only if you plan to play through it, do not enable the regular Quickstep Fix mod with Unleashed Project.
This mod has to be placed in higher priority over all other audio mods.

Many 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.[4]
All mods mentioned below, as well as several others, are listed here.


The recommended mod manager for Sonic Generations.
Compatible with older mods that have difficulty running in HedgeModManager.[5]

HD Pre-rendered Cutscenes[edit]

This mod uses the 720p cutscenes from the Ps3 version of the game.
Only Compatible with Hedgehog Mod Manager Via the 720p Video Player Code.


Mod manager for all Hedgehog Engine titles. Required for all non-exe mods. [citation needed]
Some older mods have issues running in HedgeModManager. If this is the case, use SonicGMI instead.[5]
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 folers. 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.

Graphics Overhaul[edit]

Minimal to no performance impact.
Generations renders generic shadows at 90° angles, this mod enables true directional shadows and light shafts, as well as some graphical tweaks.
Also includes a version for the "Unleashed Project v1.0".

High Resolution Shadows[edit]

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

High-Res HUD[edit]

Increases the resolution of the HUD elements.

Casino Night Done Right[edit]

Adds in the Casino Night cutscene missing from the PC version.

Unleashed Project Mod[edit]

Unleashed Project Mod comes with Sonic Unleashed day stages ported from the Xbox 360 version with many graphical and minor gameplay improvements, as well as its own hub world.
Does not work out of the box on Turing GPUs, However a Workaround has fixed this. See: workaround [1].
