Next, run Vireio's "perception.exe" file.
Select the VR / Stereoscopic 3D display option and applicable head tracker. Once open, don't close this window completely. Either keep the window open or minimized!
Review the documentation to see which titles are supported, and run your game!
If you don't see the appropriate VR or 3D format on the screen and it appears like the drivers aren't working, they just haven't injected into the game yet. In cases like this, copy all the .DLL files from the Vireio Perception "bin" directory to the game's EXE directory. The "EXE" directory refers to where the game's main *.EXE or executable file(s) is stored. The files that need to be copied include d3d9.dll, libfreespace.dll, hijackdll.dll and VR Boost.dll where applicable.
