93.71 S-3D driver

[Freke1]

Compared to 91.31 S-3D driver:
1. I've noticed that the convergence setting may "slip" during gameplay requiring a new adjustment (Ctrl F5/F6).
2. Sometimes I'm unable to adjust convergence (Ctrl F5/F6) until I turn seperation way up and down again (Ctrl F4/F3). Then it's possible.
I didn't have those problem with 91.31 so I'll go back to it.
