I have uninstalled and re installed ftb at least 3 times.
Have uninstalled and re installed java
deleted my whole .minecraft folder forcing it to remake a new one.
re downloaded several different mod packs.
tried installing optifine will not work for some reason

Have you tried using a mod called fastcraft?
I made this thread on the server i play on. It might help you

Depending on what pack your playing, i would also recommend using MultiMC.
The FTB launcher itself tend to cause issues.

mm Have you assigned more ram to mc via the ftb launcher under options?

I haven't tried fastcraft for the simple reason I plan on playing on a multiplayer server where the mods are already set. And the weird thing is I have better specs on my computer yet my friends runs faster going at least 15 fps
I am attempting to run the Direwolf20 1.7.10 v1.02 but as said before it runs reallyyyy slow.
I have tried assigning various amounts of ram to the launcher from 2gb-4gb
I have also went through the task manager and tried to set the java as a higher priority.

Thankyou two for responding

later I may try to use multimc

Fastcraft is clientside so it doesnt matter if the mods are set on the server.

Ok sooo I loaded the mods to multimc AND it went ALOT better then FTB launcher did even in the loading screen. Now theres a new problem when I try to connect. This error pops up. Any suggestions?

Actually fastcraft is very important on server side too as it affects chunk generation and a server has to do a lot of that. It is very useful to put fastcraft on the server too.

Ya ment that even if the server didn't have fastcraft you could still add it to your client side mods and not have an issue. Its not required to have server side (but does help though) .
