Pc Specs:
Solutions I've tried so far:
Doublenote: When I press ESC. My fps counter(F3) increases to 150 - 160 fps instantly, when playing the game it drops back to 20 - 25 fps.
GPU usage seems to be jumping from 1 to 99% usage constantly. When I am in the ESC pause menu the usage stablizes around 20 - 30% usage.
				
			- I7 4770k
 - AMD R9 Fury
 - 16GB Ram
 
- Extremely low framerate on every 1.7.10 ftb modpack.
 
Solutions I've tried so far:
- Reinstalled my GPU driver.
 - Delete every java version and installed the lastest.
 - Changed the java GC when running the modpack.
 - Yes, I am using 64bit java.
 - Tried different modpacks
 - Vanilla Minecraft 1.10.2 and 1.7.10 provides 400+ fps. Which functions perfectly fine.
 - Variable amounts of ram, 4, 8, 12 ... Nothing changes.
 
- Could someone provide me with a solution?
