If Cyber Engine Tweaks isn't working, here's what you can do

  • If you are on Linux/SteamDeck, make sure to follow this guide to install the right .dll overrides before reading on.

  • If your game is pirated, go here.

  • If you're experiencing performance issues, check here

  • If you are experiencing crashes caused by CET, try running Cyberpunk in compatibility mode

  • If you can't open your overlay, check Reset your keybind

  • If your CET just stopped working (without a game update) or if you've been sent here to do a clean install, see below how to Reinstall CET

  • For any other issues, read General troubleshooting.

General troubleshooting

Step 0: Go to your install directory

Go to your, since all paths given in this guide will be relative to that folder.


CET is installed to bin\x64\plugins\cyber_engine_tweaks

The log file is bin\x64\plugins\cyber_engine_tweaks\cyber_engine_tweaks.log

Your keybind is stored in bin\x64\plugins\cyber_engine_tweaks\cyber_engine_tweaks.log



C:\GOG Games\Cyberpunk 2077\

Path from the guide


Folder you go to

C:\GOG Games\Cyberpunk 2077\bin\x64\plugins\cyber_engine_tweaks

Step 0.5: Update your game and the mod

Each version of CET is compatible with exactly one game version. Nobody keeps track of those other than "the most recent ones work together".

For that reason, the Redmodding Discord can only support you the most recent version.

If there's a mismatch, then you can find a warning in the following file:


If you don't have that file, proceed to Step 2.

Step 1: Check the install folder


It should have at least the following files:

If you do not have these folders, then CET isn't installed correctly. Head to Reinstall CETand start with step 3.

Step 2: Check for a log file

If everything looks okay in step 1, check if you have a file cyber_engine_tweaks.log inside the cyber_engine_tweaks folder from the previous screenshot.

You don't have a log file

No log file means that CET isn't starting up.

  • The easiest fix is to Reinstall CET.

  • If you did that and it didn't help, check your antivirus. Most likely, it is protecting you from scary things like Cyber Engine Tweaks. Disable it.

  • If that didn't help either, update everything - Windows, your drivers, etc. You can find links and instructions in the red box on the general troubleshooting page.

You have a log file

  • If you do have it, you can open it and try to make sense of the error message. You can find more information on that here, or find help in the #cet-suppport channel on our Discord.

Reinstall CET

Uninstalling (the full game or just the mod via Vortex) can leave files behind, which will fuck things up for you after a reinstall. This section tells you how to avoid that.

  1. If you are using Vortex, turn it off (it will get angry otherwise)

    • rename bin/x6/plugins to plugins_ or

    • delete the file bin/x6/plugins/cyber_engine_tweaks.asi

    • move the folder bin/x6/plugins/cyber_engine_tweaks out of plugins (e.g. your Desktop). Do not delete it yet.

  2. Download the most recent CET from Nexus

  3. Extract the downloaded archive to your (the bin folder will merge with the one that is already there)

  4. Start the game: CET should now ask you to bind a key. If it doesn't:

    1. Update both the game and the mod (double-check if you're sure)

    2. Head to the troubleshooting guide and follow the steps in the red box at the top

  5. Optional: Restore your mods and/or settings Now that CET works, find the old directory from step 2. Move the following files/folders:

    1. Mods: the directory mods from the old cyber_engine_tweaks folder

    2. Settings: The .json files directly inside cyber_engine_tweaks

  6. Optional: delete the old folder (or leave it, it's your diskspace)

  7. That's it! You're good to go!

Reset your keybind

  1. Find the file \bin\x64\plugins\cyber_engine_tweaks\bindings.json and delete it.

  2. Start the game.

  3. You should now see a popup asking you to bind a key. Otherwise, read on.

I can't bind a key

If you do not see the popup at all, check your CET install or do a clean reinstall of CET.

Click into the "Binding..." field.

If that doesn't help, make sure to turn off all your overlays (Discord, Steam, Microsoft Game Bar, Random Useless Bloatware) or start Cyberpunk in the Windowed Borderless mode.

Microstutters and Performance

If you're experiencing performance issues with CET, first make sure to Reinstall CET as per the instructions to rule out side effects from old files.

If that doesn't make the problems go away, make sure to update Windows and your graphics driver as per the red box under Troubleshooting's section.

If that doesn't help, you can find us in #cet-support on the REDmodding Discord. Please note that people there will first suggest everything else from this guide, so you might as well get it out of the way first.

Crash to Desktop on Alt+Tab

Make sure to update Windows and your graphics driver as per the red box under Troubleshooting's section, as this is the only chance you have of getting rid of your crashes.

This is a known issue with AMD cards, and it's not something the CET developers can fix. Everyone who could fix it is informed, but such things take time. If you're on an AMD card, you can try running your game in Windowed Borderless mode. Otherwise, you just have to live with the crashes.

Frequent Issues and Solutions

I receive an error saying 'Unknown Version'

Please ensure the following:

  1. If you have modified your game's .exe file yourself, the mod will not work - to undo this, delete the file and verify your game through GOG, Steam or Epic to download a fresh copy of the newest exe.

  2. Update your game. You are using a patch that is not supported. Only current versions are supported. (current version is 1.6)

  3. You used the old version of the mod and still have the old files installed. Delete bin/x64/plugins/ and reinstall the mod.

  4. Do a repair on your installation with no other mod files installed (redscript, cet, et cetera) then install CET as you normally would and check the log file. If it still isn't working, uninstall cyberpunk 2077 and do a complete wipe of the install folder.

No log file appears in bin/x64/plugins/cyber_engine_tweaks/

Install this - if nothing happens, please make sure all of your overlays and monitoring programs are disabled. There is a list of known programs that cause issues below. If you find one not on the list, contact Arsenic_Touch via the discord.

I don't have a config file in bin/x64/plugins/cyber_engine_tweaks/

Cyber Engine Tweaks no longer comes with a config file, one is generated when you first launch the mod.

The CET window will not close.

When first launching cyber engine tweaks, it will prompt you to pick a keybind. Tilde is no longer the default. Keyboard input is blocked until a keybind is chosen. If you do not see the pop up, look below for further troubleshooting steps.

When I press the key to show the console, I only see the cursor!

Certain programs conflict with the hook that Cyber Engine Tweaks use to display the console - to avoid this, disable any software with overlays that may impact the mod (some examples below). This includes crashing the game or not launching at all. OBS graphics-hook32.dll and graphics-hook64.dll can also interfere. Do a search of your windows files to see if you have a program running them. For rivatuner, you can also open the Global file with notepad++, which is located in RivaTuner Statistics Server\ProfileTemplates and add cyber_engine_tweaks.asi to the end of the decimal in the line: InjectionDelayTriggers

Cyberpunk crashes after the intro video when using CET 1.14

  1. Open Windows Security

  2. Go to Apps & Browser control on the left tabs

  3. Click Exploit protection settings Under the Exploit Protection section

  4. In the Systems Settings tab locate Randomize memory allocations (Button-up ASLR) and High-entropy ASLR and change their settings to Use default (On).

  5. Restart your computer.

The mod isn't working with my version of the game!

Please verify that:

  1. Your version of Cyberpunk is compatible with the newest release on GitHub or Nexus (this can be seen in the menu, underneath "Quit Game")

  2. You have the most recent version of the mod from GitHub or Nexus.

  3. The installation guide has been followed correctly

  4. You have verified that the log found in bin/x64/plugins/cyber_engine_tweaks/cyber_engine_tweaks.log is 'last modified' at the same time and date as your most recent attempt to launch the game

  5. Remove all previous mods in the mods folder and try to launch the game. If it works, add your mods back one by one until you find the one that breaks CET. Some mods can break CET completely or change the overlay colour if they are not up to date.

If installed through vortex and your game won't launch.

  1. Make sure cyber engine tweaks and your mods are installed with hardlink deployment If hardlink doesn't show up under vortex, make sure the Vortex Mods folder is on the same partition as the game mods folder. This explains it more.

  2. Make sure you're using the most up to date vortex plugin for cyberpunk 2077. Check the #vortex-support channel on the discord for the latest information.

The prompt to choose a keybind doesn't appear and or pressing the chosen keybind does not bring up the mod.

There are six possible solutions to this:

  1. Ensure your game is in Windowed Borderless mode - Cyberpunk will usually make itself the topmost application on your screen if in fullscreen.

  2. Ensure you don't have any overlay or monitoring software running such as Rivatuner, Fraps, etc.

  3. Make sure your game is up to date and you are using the latest version of Cyber Engine Tweaks and that you installed it properly. (do a clean install by deleting the plugins folder, LICENSE, global.ini, version.dll files if you are running into a problem)

  4. Run the game as administrator. (this works for some people where other methods have failed)

  5. Check to make sure your antivirus software is not removing or blocking cyber engine tweaks.

  6. Do a complete reinstall of cyberpunk 2077.

I forgot the keybind to bring up the overlay for CET.

  1. Delete the bindings.json file located inbin/x64/plugins/cyber_engine_tweaks/ and start your game, the overlay will to choose a new keybind should come up. If it doesn't, check the known list of programs that can interfere.

I can bring up the CET overlay but my image is frozen on intro videos

If you see in your log that your game is freezing on CRender and you have problem like this you should try steps provided below.

1. If you are using mod manager disable CET temporarily, if you are not using mod manager then follow uninstallation guide. 2. Launch the game without CET and disable FSR/DLSS 3. Install/Enable Cyber Engine Tweaks and launch the game, the problem should be gone.
