In-Game Settings

Changes can be made to many TriDef 3D Ignition settings while playing a game using the on-screen display (OSD) or hotkeys. Please note that changing OSD settings may cause the display to be blanked for several seconds as the game re-initializes.

The following keys can be used to open the OSD and navigate within it:

Num 0 OSD Open/Close
Num 5 OSD Select
Num 8 OSD Up
Num 2 OSD Down
Num 4 OSD Left
Num 6 OSD Right
Ctrl+Num 4 OSD Left (Fast)
Ctrl+Num 6 OSD Right (Fast)


Hotkeys provide quick access to in-game settings without the need to navigate through the OSD. The default hotkeys are listed in the following table. Hotkeys can be customised for all games by selecting Tools → Options…, or for a particular game from the Game Properties dialog.

Alt+Shift+F1 Show List of Hotkeys

3D Menu

The 3D sub-menu controls rendering of the stereoscopic 3D effect. 3D rendering can be turned off to render the game without stereoscopic effects, in a pass-through mode.

The Scene Depth and Percent In Front control the strength and positioning of the 3D effect respectively.

TriDef 3D Ignition has a unique method for optimising the 3D effect, called Auto Focus. Auto Focus detects the location of objects in the scene and modifies the 3D configuration accordingly. Alternatively, if you are an advanced user and want manual control over the focus parameters, then turn Custom Focus on. This allows you to set the Near Plane and Far Plane manually.

Performance Menu

Power 3D is another innovative feature of TriDef 3D Ignition that is not available in other commercial stereoscopic game drivers. By default TriDef 3D Ignition is configured to render the same scene twice, with a small viewpoint shift (in the same way most other drivers operate). This produces the best quality results but is very resource intensive and quite inefficient.

The Power 3D mode is a faster method of approximating a viewpoint shift based on the principles of image based rendering. There is a trade-off in terms of 3D image quality, which may be noticable at the edges of objects but it is likely that you will get a significant increase in frame rate if you switch to Power 3D mode.

In normal 3D mode, the frame rates of most games will decrease by 50% compared to 2D mode. With Power 3D turned on, the performance will often be much closer to the 2D game performance.

The Quality parameter is also designed as a means of trading image quality for speed. By reducing the quality the frame rate can be increased.

The performance of TriDef 3D Ignition is dependent on factors such as the graphics card and graphics drivers. 3D Texture Copy allows the user to switch between different methods of passing 3D textures around the system to assess the impact on performance. The Auto setting attempts to find the best setting for your system automatically.

Laser Sight Menu

2D gun sights can be inaccurate when targeting objects in a stereoscopic 3D game. The Laser Sight menu provides an optional 3D Laser Sight for improved targeting in first person shooters. The Laser Sight can be turned on and off using this menu.
It is also possible to customize the appearance of the sight by changing its Color, Transparency and Size.

Output Menu

The Output option allows you to change the 3D output from the Normal display profile. The Above-Below option displays the 3D stereo pair stacked vertically in the image frame. When available, the Left-Right output option displays the 3D stereo pair side by side, stacked horizontally in the image frame.

The Swap Left/Right option reverses the order in which the left and right eye images of a stereo pair are displayed.

Image Stretch enables you to stretch the 3D image horizontally to fill the screen. When the stretch is set to 0 the 3D image is rendered at the resolution determined by the game. By default the 3D image is stretched to cover the entire width of the screen (stretch value 100). If the aspect ratio of the game resolution differs significantly from the aspect ratio of the display objects may appear distorted and your preference may be to reduce the image stretch.
Please note that this control is disabled for DirectX 10 and 11 games.

On some displays, the image may extend outside of the screen area. This is referred to as overscan and leads to cropping. The Image Overscan setting allows you to control overscan by expanding or shrinking the image to avoid undesirable cropping. Please note that this control is disabled for DirectX 10 and 11 games.

Soft Interlacing improves 3D rendering when using line-interlaced display types. For other types of 3D display this setting has no effect.

Help Menu

The Help menu includes a list of Hotkeys and an About option which displays the version number and Game Profile currently in use.

Take 3D Screenshots

3D screenshots are stored under a “TriDef 3D” subfolder in your “Pictures” (or “My Pictures”) area. They are created in several different formats: TriDefPhoto, above-below, and anaglyph. TriDefPhotos can be viewed using TriDef 3D Media Player.

Please note that it may not be possible to take a 3D screenshot during cinematic sequences and on some menu screens.

Restore Default Settings

Select this menu item (or press “Alt+Shift+R”) to reset the current game’s 3D settings (Scene Depth, Percent In Front, Custom Focus, Laser Sight, etc) to their default values.

Profile Menu

The Profile menu allows advanced users to create a user profile for games that are not currently supported. This menu will only be displayed when using the “Generic” DDD profile or a user profile.

The Focus sub-menu allows more advanced configuration of the 3D focus parameters.

TriDef 3D Ignition optionally separates the scene into several zones: Gun, Scene, Sky. It is possible to configure auto focus parameters separately in each zone to get the best possible 3D effect.

When using multiple zones (Gun, Scene, Sky) it is possible to configure the contribution of each zone to the total 3D effect. For example, it is possible to set the Gun zone to occupy 20% and the Sky zone to occupy 30% of the 3D space.

The three fixed modes: Fixed 1, Fixed 2 and Fixed 3 essentially turn Auto Focus off. In this configuration the 3D configuration is fixed and does not adapt to objects in the scene. Select one of the fixed modes if the Auto Focus is not working optimally (such as fluctuations or a poor 3D range). The three different fixed modes make different assumptions about the location of objects in the scene.

The Expand mode is a compromise between Auto Focus and fixed focus. The Expand mode cumulatively adjusts the 3D configuration over time as new objects are detected in the scene.

The Submode option is available when the mode is set to Auto. If the 3D appears to jitter in some situations, then the Smooth setting may correct this.

When in Auto Focus mode, the Stability parameter provides fine-grained control over the focus speed. Low values result in fast focus changes, while larger values ensure the focus changes more slowly.

Additional constraints can be placed on the behaviour of Auto Focus by controlling the minimum depth range and minimum object size. Min Depth Range determines the smallest 3D volume, regardless of the objects in the scene. Min Object Size enables small objects to be excluded from the Auto Focus calculation.

The Depth Range Scaling option, when switched on, uses the viewport’s depth range to affect the 3D configuration. If the game has not set the viewport depth range appropriately, this can impact the 3D quality. When this option is turned off, the viewport’s actual depth range is ignored and a default value is chosen.

3D Object Detection can be set to Custom, Mode 1, Mode 2 or Mode 3. Select a combination of methods to detect whether a 3D object is drawn.

GUI Threshold sets a cut-off point in depth so that everything placed in front of it is classified as a 2D graphical user interface (GUI) element.

GUI Offset can be increased to make the 2D GUI, as detected by GUI Threshold, pop out of the screen.

Matrix Names allows advanced users to pick which vertex shader matrices are used to draw 3D objects. In general, all matrices containing the word “projection” or “proj” should be included, but the word “light” or “shadow” should be excluded.

Some games use row-major matrices to draw 3D objects. Set Row-Major Matrix to Yes if all of the 3D objects appear to have been transformed incorrectly.

To optimize the 3D appearance of a game’s gun, turn Gun Detection on and set a Gun focus zone in the Focus sub-menu. Please note that it may not be possible to detect the gun in some games.

GUI Detection is available in Power 3D mode. TriDef 3D Ignition attempts to detect the graphical user interface (GUI) and draw it in 2D. Increase the GUI Detection level if the GUI is not drawn in 2D. If some 3D objects are wrongly rendered in 2D, then decrease the GUI Detection value.

Go 2D on Fullscreen Effect ensures everything is rendered in 2D after a fullscreen effect is applied.

Go 2D on Square Texture ensures that square sized textures are rendered in 2D.

Track 3D Objects on Main Surface enables tracking of 3D objects drawn on the main surface so that the focus can be adjusted. This is only effective when the Scene focal zone is set to Auto or Expand.

Track 3D Objects on Any Surface is similar to the above option, however in this case the tracking applies to 3D objects drawn on any surface.

Disable Incompatible Shaders ensures that objects are not drawn if one of the shaders is not 3D compatible. This is only effective when 3D Texture Copy is enabled.

If the sky is not displayed in 3D correctly, turn Detect SkyBox on and set a Sky focus zone in the Focus sub-menu. Please note that it may not be possible to detect the sky in some games.

In the Advanced Settings sub-menu, Depth Map Correction can be used in normal 3D mode to correct shadow issues for some games. Turn on Reverse Depth if the depth appears inverted in Power 3D mode.
