You can play the whole campaign in VR so it gets bonus points for that, pretty solid 8 hours long and then they added a survival mode.
I played the whole campaign in VR and it was all pretty smooth sailing, I super sampled it maybe that helped and was using a hp g2 so that probably helped aswell. The early planes were trash because the canopy on all of them restricted vision but once I got an f16 that fixed that, beautiful canopy with nothing obscuring your view.
edit: Video of first mission in VR, some stuff later is way better visually speaking but I don't want to post spoilers.
