Samsung Odyssey+ VR headset. iRacing is massively improved by having such a wide field of view and being able to glance at the car next to you.
Dirt Rally 2 is the closest I have come to barfing in VR and I’ve worn a VR headset on a roller coaster. For some reason the VR implementation has your head moving with the horizon instead of the car which instantly gives me motion sickness. Have the head move with the car and it would be so much better.
