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. .
For people having problems with the size of text on large resolutions or on small displays, getting any variation of the Comfy Font from here , and placing the .dzip in the CookedPC folder will make it bigger and more visible.
Improves the in game HUD by decreasing the size of the lock-on crosshair, adding in a combat crosshair, a minimap direction pointer, and the ability to select signs, swords, and pocket items without clicking (meditation still requires clicking since it's in the center). 
Improves the in-game inventory through various helpful tweaks. .
- This mode does not work with Enhanced Edition installed. The menus will appear blank and unusable.

GPU/CPU Intensive Settings
Enabling the following options will result in a significant reduction in in-game frame rate:
- Cinematic Depth of Field: Of the three depth of field options available, cinematic depth of field results in the biggest performance decrease. Enabling it applies a stylised depth of field effect to cutscenes and dialog sections. It is important to note that enabling it essentially enables depth of field anyway, so this option should be used in conjunction with 'Depth of Field - Cutscenes'. Again, it's performance impact is significant.
- Light Shafts: This option adds realistic light glares as sunlight filters through trees, etc. However, in graphically busy areas such as forests it can result in a major performance hit, and as such disabling it is recommended on lower end systems.
- LOD [Level of Detail] Distance: This decides how far away detailed objects (such as some shrubbery, objects, etc.) are rendered. The higher you set this value, the further away such objects will be rendered, and the larger the impact on FPS. As the difference between the 'Near' and 'Far' options is visually negligible in almost all instances, 'Near' is recommended for most systems. For systems which only just meet the system requirements, consider using the 'Minimal' option.
- Motion Blur: Enabling this option will result in a stylistic blur effect rotating the camera, which also results in an overall performance decrease.
- SSAO [Screen Space Ambient Occlusion]: This option improves the overall quality of shadows in-game by increasing their definition and contrast. Enabling it will also largely impact performance.
- UberSampling: This option essentially requires your system render everything on-screen multiple times before displaying, resulting in a drastic increase in overall visual detail, maximising object detail and smoothness, with the expense of a huge performance hit. It is only recommended to enable this option if you have a very high-end system.
- Wet Surfaces Rain Effect: This option is only active when it is raining in-game, and adds a semi-transparent filter to many objects to make the rainfall impact appear more realistic. It can result in a sizeable performance hit during rain sequences, however, so disabling it is a good idea for performance increases.
Note all other graphics options can be enabled/disabled with little or no FPS impact. Note that whilst 'Texture Downscaling' has a significant visual impact on the 'High' setting, reducing downscaling to 'Low' or disabling it entirely can drastically improve the look of the game with very little performance impact.
The Witcher 2 makes use of a sharpening filter that increases the sharpness of the game's visuals. While this setting has a negligible performance impact it does cause increased aliasing and adds an unnatural sheen to many objects, if those bother you it can be disabled with an INI tweak.

Continued Stuttering During Gameplay
There are two possible causes for this issue:
- Incorrect texture settings. Launch the game and navigate to the 'Options' menu on the launcher. Locate the option for 'Texture Memory Size (MB)'. This is how much of your graphics card RAM is allocated to texture storage. For a 512 MB card, it is recommended set this to 'Small', whereas for a 1 GB card set this to 'Large'. Allocating insufficient memory for texture storage can result in delayed texture rendering and constant stuttering during gameplay.
- Rendering too many frames in advance. To fix this use your GPU configuration panel to manually set the value of "Maximum Pre-Rendered Frames" (Nvidia) or "Flip Queue" (ATI) to 1. You may also need to limit framerate and/or enable Vsync.
First Time Setup Lock
The game attempts to reinstall the Microsoft .NET Framework 4.0 every time the game is launched.
