I also encountered the same problem. My PC configuration is RTX2080, I6700, 32GB RAM @2400, SSD, Reverb G1, and in VR mode I can run the previous version stably at 45fps, but in the latest version, only 32~ 41fps, and there are obvious freezes, the experience is very bad, lowering the water quality and visible distance did not improve, please check what is the reason, hope can be recover soon.
