The game is Z3D only, Not all games have G3D.
Configuring it for FullVR should be fairly easy unless you happen to have disabled automated settings. vorpX sets the FOV automatically under normal circumstances, all you really have to do is choosing a resolution quality in the vorpX menu (DirectVR page) thatlooks decent without costing too much performance.
Not sure re your issue with switching to cinema mode. Try to reset the profile to default first. If you already have tweaked a lot, settings might be messed up. Shouldn’t really affect the switch to cinema mode, but who knows.
