With cockpit sims you can get sick two different ways. If your computer can’t keep up and you get stutters, you may not even realize it’s happening but it can be a nausea inducer. You might want to keep an eye on frame rates until you know they are good and adjust settings as necessary.
The other cause is just having what you see be moving when you don’t experience the same thing. The more cockpit you have around you and the gentler your flight, the less tendency for feeling sick. Aerobatics in the Bücker would probably be worst for that but are a kick.
Also, based on my experience I would suggest short initial flights with time breaks in between. Don't fly around for 45 minutes or more in shear amazement like I did, not realizing I was slowly feeling the effects of VR sickness
It's a real phenomenon (motion sickness without motion). I had to put the HMD down for a couple of days, then start out with brief flights until I built up my tolerance (VR legs). https://www.reddit.com/r/oculus/comme…yed_30_mins_of/
Now I can fly for hours with no issues.
Love it! No going back to 2D monitors for me. Can't wait for higher resolution (I have a CV1).
