All I can say is that I think Pimax intends to do that, but I think they were way too optimistic and “bit off more than they can chew”. Unfortunately, that means we must all be patient. Have you tried playing seated games using a joystick, steering wheel, or HOTAS? There are a number of good VR games that use those inputs.
If you only have a gamepad, I suggest you try Assetto Corsa. I like it a lot and it has the best gamepad control that I’ve seen in a racing game: Tilt left or right to steer. It’s much better than trying to steer with a thumb-stick.
Assetto Corsa is only $20 on Steam and is likely to go on sale at some point this summer. It’s great in VR (although the menu screens are displayed on your flat monitor). That is, only the driving part is in VR. If the in-VR text is too small, reduce the size of the monitor game window, since the VR text size seems to be based on the mirror window res. Also, you’ll probably want to tweak some of the in-game graphics options, in order to get a good VR experience. Iirc, turn off AA and post-processing effects and reduce the shadow quality a bit. If you do get the game and need help tuning it, you can PM me and I’ll share my settings.
