    There are three things that you need to take care of once for each game:

    1. Enhancing the field of view (FOV), otherwise the image will appear zoomed in.
    2. Adjusting the head tracking sensitivy in the vorpX ingame menu.
    3. Choosing the optimal 3D mode dpending on your PC’s performance.

    1. Field Of View

    Setting up the FOV correctly is crucial with the Play Style option set to Full VR. With a wrong FOV in Full VR mode the image looks zoomed in and/or warped. For many games vorpX can handle that automatically, either by auto-adjusting game settings or with the DirectVR memory scanner.

    If vorpX cannot handle FOV automatically for a game, the ideal options are:

    • Setting the FOV in the game options if possible. The right value usually is 112° horizontically or 96° vertically. Some games however use arbitrary numbers, so these values aren’t always right!
    • Setting the FOV with a tool like Flawless Widescreen or by tweaking a game’s config files. The PC Gaming Wiki is a great source of information in this regard.

    If the actual game FOV cannot be set high enough or changed at all, the following workarounds exist. You can combine them for the best possible result.

    • Use one of the letterbox aspect ratio modes in the vorpX ingame menu and/or the Image Zoom setting to compensate for a low FOV.
    • Check whether 4:3 or 16:9 resolutions work better. Depending on the game one may be better than the other in regard to FOV.
    • Use the 3D FOV Enhancement in the vorpX ingame menu (availabe in Geometry 3D games).

    Should you encounter a game where it is not possible to get a good a result with the methods above, you can set the Play Style in the vorpX menu to Immersive Screen Mode or Virtual Cinema Mode, which don’t require a perfectly tuned FOV.

    2. Head Tracking

    If a game does not support DirectVR head tracking, vorpX handles head tracking relative to your individual mouse sensitivity in a game, so it might need some tweaking. If the view rotates either too fast or too slow while turning your head, adjust the Sensitivity on the Head Tracking Settings page of the in-game menu.

    A good way to calibrate mouse based head tracking is placing yourself directly in front of a wall in the game and then rotate your (real) head 90° degrees. Check how far your ingame view rotated while doing that and lower/raise the sensitivity if necessary. Doing this two or three times should usually suffice to get solid tracking.

    3. 3D-Mode

    vorpX uses two very different approaches for creating Stereo 3D. All supported games have Z-Buffer 3D, many of them Geometry 3D. Geometry 3D offers the most lifelike 3D experience, while Z-Buffer 3D is about twice as fast (but has ‘less 3D’). Especially in resource hungry games you should consider the Z-Buffer mode. A high framerate is very important for a great VR experience, often more important than perfect Stereo 3D.
