Yes, but not (yet) in DCS. I've been playing The Lab, and throwing mugs around. The small robodog brought them back, and I wanted to kick the mug. Then I realized it's not real and I don't have legs in VR...
I instantly got sick in games with 'traditional' locomotion - I mean WASD + mouse or game controllers and I have to recover for a while. DCS, FSX are fine, but sometimes I feel dizzy during heavy maneuvers. I don't have any problems in roomscale games.
