Windows .exe FPS ISSUES

[TheRealNicko]

Hey Guys, Recently formatted and re installed FTB onto my computer and have come across a lot of fps issues. I have tried many fixes, re installing java 64Bit, added JVM arguments, reinstalled FTB but to no avail. I can play regular minecraft Lag free and all other games on my computer I have no problems so its not a GPU problem. Note that when I fit the render settings from fast to fancy and then back again, I instantly jump from 5-15 frames to 50 frames +

Any help would be appreciated

try allocating more ram in the launcher options 2GB seems to be a good level for most.

I use 3GB myself . Anyway, if you still have low fps after the world is done rendering, check some options and see if there`s anything you had lowered before. If none of those solutions are satisfying, i would recommend adding optifine to the modpack

Using/used optifine? Same size texturepack as before? Same size builds as before?
