Don't try to push through it, you fucking retard.
Stop immediately when you feel dizzy or you gonna make things A LOT worse, to the point of not being able to play VR at all.
Short bursts often, while gradually increasing the play sessions. 
>I also have a bad gpu, could this also be a reason?
Check if you are reprojecting, bad perf is indeed harder to tolerate.
