I was inactive for 5 days and now I'm experiencing some bad FPS issues. I have optfine installed if you're wondering. Please leave your suggestions. I really need it. Thank you
Check render distance, lower it if you have to, make sure all of your video settings are minimal, VSync on, Fast Math on. From there, you can put up what you really want to
Yea, turning down render distance should help quite a bit. There are some other options you can play around with such as graphics, which I play with using Fast, as there is really no need for Fancy.
