Ok, so I have a top of the line PC that I use for FTB, but when I play I use a texture pack. Sphax 64x to be exact. However, as of recent a new version of the DireWolf20 pack (the pack I use) came out and whenever I use a texture pack the amount of lag I get is unbearable. I don't know why, it only appears if I use the texture pack. It never happened before. Also, it does not seem to matter at all how low my settings are, my frame-rate drops to about 5, sometimes 1 (as crazy as it sounds). If anyone can help it would be much appreciated. Also, yes I am using OptiFine.[DOUBLEPOST=1362178793][/DOUBLEPOST]Yes, I realized I misspelled the word "fixed"
