Seems like you were hoping for too much- there is only so much they can do when the computer can’t provide the required framerate. Expecteing brainwarp to be some kind of holy grail is just naive, any reprojection or motion smoothing I’ve ever experienced is sickening.
For those who can deal with the artifacts, good for you. If you can deal with it and somehow don’t get sick, that’s great. Personally, any reprojection makes me sick, and without it I can play a VR title for several hours without getting sick at all. Really not sure how anyone thought brainwarp was going to be anything special.
I did try the brainwarp beta, and it was absolutely terrible. I downgraded to .91 almost immediately after and intend to stay here until the community beta tests the coming updates for me.
