I looked over babycat’s very informative post and I definitely see lower fps on my end but its like WAY lower than the estimated 30%. Using spawn as an example I used to average 270 FPS with 1.16.4 and now I'm getting like 100 and I'm sure the new spawn may be playing a factor as well as other factors. Also I understand that 100 FPS is still pretty high but it's noticeable for me and feels way different compared to the 270 FPS im used to as well as that's 100 FPS at spawn. The reason I made this post is to just ask what people have done to cope with the FPS drop if they have at all. I have messed with optifine settings and what not but I don't wanna turn my chunk render distance to 4.
