As of the new update, framerates are being completely crippled with worlds that are not very intensive at all. Post processing of any kind is also completely bugged out and fails to work with any settings.
I.E 91 frames in Room In The Rain dropping to 75-80 and other places that are a bit more instensive that would be 70-85 dropping to 9-10 on an RX 580 and Ryzen 7 2700X with 16 Gigs of ram
I should also mention I was the only person in each of the worlds.
