This is a lengthy post with details on the configuration settings I used in initial experiments getting Oblivion to work with the rift. Game results will depend on factors such as graphic card, IPD, rift lenses and personal preferences, so these settings may not be perfect for everyone. Hopefully they will provide a useful starting point for new users.
INI Settings
Change settings in the "Oblivion.ini" file in the "My Documents\My Games\Oblivion\" directory. Make a backup of this file before you make any changes.
To disable the introductory movie sequences. This is optional, but helps speed restarting while you experiment with settings. [General]:
SIntroSequence= SMainMenuMovie=
To disable combat. This is temporary, but helpful while experimenting with configuration. [Combat] bDebugCombatAvoidance=1
To unbind “change POV” from the middle mouse button. Optional for Tridef, required for Vorpx to enable EdgePeek. [Controls] Toggle POV=0013FF05
Graphics Card
For an NVIDIA Grapics card. In the NVIDIA control panel:
Under “adjust destop size and position”
Perform Scaling On: GPU Select a scaling mode: Full Screen
Under “Manage 3D settings”
Vertical sync: Off
I left the resolution to the default for my main monitor (1920 x 1200) and configured it to duplicate the displays.
Oblivion MODS
If you change the FOV in the game settings, Oblivion will reset to the default of 75 whenever you talk to someone. The best way to increase the FOV for the rift is to install the “FOV Modifier” mod from the Nexus site. This is a great mod that will keep your requested FOV from changing in the game and will also automatically reset the FOV to 75 when viewing menus. The mod requires the obse, so be sure you start the game from the obse loader once the mod is installed. http://oblivion.nexusmods.com/mods/23080/?
To avoid problems with mods, I strongly recommend that you install Oblivion somewhere other than the default windows programs files directory.
Vorpx Setup
Right click on the Vorpx tray icon, and select “Create Desktop Shortcut”. Browse to the “obse_loader.exe” in the Oblivion installation directory and create the shortcut. Launch Oblivion from the shortcut. Load a save game. Use the “Delete” key (DEL does not work for me) to open the Vorpx configuration menu.
Once the beta is installed, open TriDef 3D Ignition. Click on the “Add Game” button. Click on “Add a game manually”. Browse to the Oblivion installation folder and select “obse_loader.exe”. Click on “Click here if you game is not in the list”. Enter a name. Under game profile, select “Oblivion”. Click Finish. Launch Oblivion from the shortcut in Ignition. Load a save game. Use “Num 0” to open the Tridef configuration menu.
3D
Custom Focus: Off
HMD Settings
World Scale: 1.0 Head Tracking (Do not select Calibrate)
Yaw Scale: -1090.0 Pitch Scale: -1250.0
Force FOV: Off Output Quality: High
Vorpx Results
The 3D looks good. For the most part there are no depth artifacts (hair, rug fringes, horses tails, etc displayed at the wrong depth). However, the compass on the HUD renders the full compass across the screen instead of just the part in the compass window. This creates flickering at the bottom of the screen as you move or look through the world.
On my graphics card, the frame rate falls below 60 frames per second with this configuration. This does not bother me too much unless I run a lot. If you are sensitive or new to the rift, this could be a problem.
TriDef Result
The visuals looks good. There are depth artifacts, but the HUD compass is ok.
Same problem with the frame rate.
Notes
If head tracking does not start, try unplugging and plugging the rift usb cable. I need to do this every time I reboot.
The Oblivion HUD is more suited to the rift than that of many RPG's and it is very readable. The Vorpx EdgePeek and the TriDef zoom function both work well, but you may prefer one over the other.
In Vorpx, if these setting do not look good to you, try experimenting with the following settings first:
Set screen resolution to rift default Try changing the AspectRatioCorrection mode Experiment with the Vignette Scale
In TriDef, it these settings do not look good to you, try experimenting with the following settings first:
Set screen resolution to rift default Experiment with World Scale
I used a mouse and keyboard instead of a gamepad. Although the HUD is very readable, there is still the problem of finding the controls on a keyboard you cannot see. I plan to experiment with the Hydra as a controller next.
The graphics card used for testing is an NVIDIA GeForce GTX 560 Ti.
