{SOLVED} FTB Unleashed Launched and Lags Whole PC

[HeyImZach]

When I launch FTB it lags my whole PC reducing everything I do to about 2 FPS. In order to play the game it take at least 20 times of launching and restarting the game to get it to work.

PC Specs:
CPU: AMD FX-4100 Clocked at: 3.6 GHz
RAM: 8 GB
OS: Windows 8.1 64-Bit
GPU: Nvidia GTX550Ti
Java: Java 8
Texture Pack: Sphax FTB Unleashed x128

If you are still having issues then go here for help with obtaining and posting logs.

Also is this a new world or existing one? You also might want to try using java 7 instead as version 8 is not officially supported by the launcher and may cause issues.
