Method for Stereoscopic 3D in VR with Headtracking in Strike Fighters 2 - Geo11
The latest zip download contains 2 files:
1. a PDF which outlines the steps using freeware programs, wrappers and apps, which can be used to implement VR in stereoscopic 3D in Strike Fighters 2 and it's associated mods;
2. A custom d3dx.ini file, which should be used to replace the default d3dx.ini file that comes with geo11.
Why the custom d3dx.ini?
I've recently had time to take a closer look at how geo11 functions and have enabled a number of settings which allow you to play SF2 in stereoscopic 3D VR in the native directX10 mode (i.e. you no longer need to set ForceDX9=TRUE in the options.ini). In addition, I've identified the shader responsible for the HUD in game and implemented a fix so that the target and waypoint markers appear correctly in game.
Back story:
Over the years I've tried many methods to get SF2 working on either a 3D monitor or in VR using programs such as vorpX or Tridef, as well as many others, but have never been happy with the results; however, using geo11 and dgVodoo2, I'm finally able to play in VR with proper 3D. Geo11 is a very clever piece of software, which is, I quote "a replacement for 3D Vision for DX11" and allows you to generate a very nice 3D image in VR using the latest Nvidia drivers in either Windows 10 or 11.
At this point I'm not sure if this will work for anyone else who is not using the same tech i.e. HP Reverb G2 VR Headset and running an Nvidia RTX 2080TI or RTX4080 GPU but please let me know if you have any success with similar hardware or something very different. Also a very similar method works for the Strike Fighters 1 series of games and if anyone is interested I'll post the additional steps here.
For anybody else trying this - Good luck

What's New in Version 2.0.0
Released November 13, 2025
Version 2.0.0
- Revised methodology for implementing VR
- Added custom d3dx.ini file in zip, which is to replace default d3dx.ini that comes in geo11.
The custom d3dx.ini does 4 things:
1. allows you to play SF2 in the native directX10 mode;
2. fixes the frame rate;
3. allows you to adjust the dX10 version of SF2 stereoscopically so you see real 3D;
4. makes the target and WP icons appear correctly in game.
- Tested in Windows 10 and 11
Update 26th May 2023
I just realised that I still had the original version of the file (v1.0.0) linked via the download file tab, this has now been corrected
Version 1.0.2
- Revised information included and improved formatting of document
- Added details on solving non-native resolution/upscaling errors in geo11
Version 1.0.1
- Uploaded in zip format, added image and corrected some typos
