Small correction :
You have to pass "-window-mode exclusive" in place of "-window-mode=exclusive" as command line argument to force exclusive mode and 3d stereo. I'm used to play on pc with a lot of 3d games and Freerider is pretty good. There is just 2 grey polygons along the horizon and Carpark is broken (mainly caused by lights and shadows I think) but it's still very fun to play like this.
Thanks you Freerider for this game. I can continue to test future updates in 3D if you want.
Thank you relaxfpv for this topic. (I'bought the game after reading it)
