I disabled all VR plugins in Unreal Engine, it should help. Try to run the new version v0.0422.
Yes. that fixed it! One more thing (you're probably getting sick of these): whenever I die, my inverted Y axis gets disabled until I go into options and turn it off and back on again. But I appreciate you having it in there! Many small indie games don't allow you to invert they Y axis and I understand the reasons but boy does it drive me nuts.
Love the visuals, by the way.
