Hi and welcome to the forums.
What you are describing is vr sickness. Common issues causing this can be.:
Pc not upto vr spec with lost frames and reduced fps. What score does your pc have in steam vr?
Games that have you move in vr without your RL body moving, can make the brain sense the lack of motion in RL. You were playing a racing game where the ship is floating, may affect some people.
IPD set incorrectly can cause your vision to be strained while trying to focus
Looking left or right while moving forward can cause nausea
If your new to vr, short use of vr is recommended to get your vr legs, short time in vr is best say 15mins on 15mins off is a good start.
