No Intro Videos Mod

This mod skips all intro videos except the logo by CD Projekt.

Using Windows' built in symlink functionality, make a symbolic link of launcher.exe (that Steam uses whenever you Start the game) that shortcuts directly to the actual game executable, witcher2.exe. Not tested with Proton/Steam Deck.

Issues fixed

Linux version crashes on start

The Linux port of the game is not native but uses an outdated compatibility layer. If you have a Vulkan compatible graphic card it is highly recommended to use the Windows version of the game through Proton.

Go to Properties and enable "Force the use of a specific Steam play compatibility tool" and make sure the latest Proton is selected. If the game doesn't start, you may have to copy some files: cp -r $HOME/.local/share/Steam/SteamApps/common/the\ witcher\ 2/bin/config/* $HOME/.local/share/Steam/SteamApps/compatdata/20920/pfx/drive_c/users/steamuser/My\ Documents/Witcher\ 2/Config ^[12]

First Time Setup Lock

The game attempts to reinstall the Microsoft .NET Framework 4.0 every time the game is launched.

Option 1: Registry Change (recommended)

Option 1: Registry Change (recommended)^{[citation needed]}

Open Notepad, and enter this code:

;For 64 bit systems (x64)
 Windows Registry Editor Version 5.00
 [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Valve\Steam\Apps\20920]
 "DirectX"=dword:00000001
 "VCRedist"=dword:00000001
 "dotNetFx40"=dword:00000001

;For 32 bit systems (x86)
 Windows Registry Editor Version 5.00
 [HKEY_LOCAL_MACHINE\SOFTWARE\Valve\Steam\Apps\20920]
 "DirectX"=dword:00000001
 "VCRedist"=dword:00000001
 "dotNetFx40"=dword:00000001

Save as a .reg file, and then double click on it.

Option 2: Folder rename

Option 2: Folder rename^{[citation needed]}
Go to the installation folder. Rename `redist`. Launch the game.

Black Screen During the Cut-scene after the First Chapter (Enhanced Edition)

Black Screen During the Cut-scene after the First Chapter (Enhanced Edition)^{[citation needed]}

A special cut-scene should be played off, but instead you receive a black screen and only hear Dandelion's voice.

Possible Fix: Change your screen format to 16:9 ratio. It's working for most people.

Random Crashes while Saving Game, Loading a Save Game or AutoSaving

Random Crashes while Saving Game, Loading a Save Game or AutoSaving^{[citation needed]}

The game will crash to desktop without any error messages.

You may encounter this right before, after or during cut-scenes (i.e. when the game is auto-saving).

The solution modifies the Windows Registry in order to allow Windows to allocate more memory to other programs. More information here.

If the problem persists, either deactivate the real-time protection of your antivirus program or add exceptions for The Witcher 2 folders and executables to it.

Crashes on saving or auto-saving: this will occur in 32bit systems due to low memory. To solve it, press windows key + R key to bring up the Run window. Write "bcdedit /set increaseUserVa 3072" without the " and press ↵ Enter. Reboot the PC. In order to undo this change you can bring the Run window up again and write: "bcdedit /set IncreaseUserVa 2048" without the " and press ↵ Enter. Reboot the PC.

Crashes on loading save games: this will occur in some systems if you accumulate too many MBs worth of savegames. To solve it, go to your save game data folder and either delete or move most of the stored saves.

Crash to Desktop German version^{[citation needed]}
If you have the German version there is a memory leak on display of the character ß You can test this with constantly opening and closing the chest. About 10 times should make the game crash. Here is a mod to fix the problem: https://www.nexusmods.com/witcher2/mods/850/

AMD GPU users double input

If you have AMD Gaming Evolved installed, make sure the program is not running while playing.

Long loading times when resuming a save

Large number of saves will result in longer loading times when you open the menu for loading a save. To fix delete unused saves or move them to a backup location.

Nvidia Ambient Occlusion Flicker

When using ambient occlusion forced through Nvidia Inspector, there is a noticeable flicker while moving around, this is caused by higher-detail meshes being loaded in. To fix this issue, in the user.ini under the "rendering" section, increase "MeshDistanceScale" to a much higher value; e.g.: "MeshDistanceScale=100". This will also reduce non-AO related pop-in and in general make distant objects look better. Note that this potentially has a performance impact, test different values to see what works best on your system.

Linux port

The Linux port is not native, and is packaged in a Wine-like compatibility layer called eON. eON is used for some other titles (such as Stronghold 3). It is not based on Wine, but has a similar reimplementation of the relevant Windows APIs.

Modifications

Market Price Mod

Market Price Mod makes buying and selling prices within markets more fair to the player. It reduces the 24:1 ratio between buy to sell prices and reduces it to 5:1 as seen in the original game.

Comfy Font

For people having problems with the size of text on large resolutions or on small displays, getting any variation of the Comfy Font, and placing the .dzip in the CookedPC folder will make it bigger and more visible.

Full Combat Rebalance

Full Combat Rebalance is a mod created by the developers of the game. It includes many changes, including an 80% increase in responsiveness per Geralt's animations and decreased time for returning to exploration after combat. The file is 1.5 GB in a compressed format.

Highly recommended to use with FCR2 Fixpack and QoL compilation

AI Upscale Textures

AI Upscale Textures contains over 600 character and object, 1100 original environmental and 150 weapon textures with increased resolution quality x2 (i.e. 512x512>1024x1024, up to 4096x4096) in AI Upscaled Characters Textures X2 VERSION OPTIMIZED, AI Upscaled Environmental Textures X2 VERSION OPTIMIZED and AI Upscaled Weapons Textures X2 VERSION OPTIMIZED. With minimal impact on performance.

Utilities

The Witcher 2 Savegame manager allows for the easy backup, management, and removal of The Witcher 1 and 2 save files. Can tremendously improve the clutter of savegame files.
The Witcher 2 Tweaker allows for greater customization of graphics options to further tailor your game for the PC. Also has helpful tips for improving performance on some computers as well.
