Recently my frames for FTB drop horrifically low, to the point where it's a slide show. I'm unsure of what is causing this, especially because when I first load it, it runs fine for a few minutes. This all happened after I started loading more land in the twilight forest, so that may be one of the issues that's causing this or me. Another thing I'd like to add is that I did not have this issue a week ago, and was able to run FTB perfectly fine. Any way to fix this?
