Tridef works nicely in games other than those in Airspace.
When running Visualizer, Tridef reports that it didn't use DX 9,10 or 11.
I haven't installed every single game but e.g. Freeform is mono 3D too.
I tried to run Airspace by adding it to the 3D launcher application and
that apps in there would inherit stereo capability but nothing works.
Can't find direct links to the app executables either.
