Okay, quick run down of my comp. It's a microsoft windows 7 home premium 64 bit-basic pc. I have 4 GB of installed physical memory. I recently added the code -XX:MaxPermSize=128M to my advanced options in FTB and deleted and reinstalled both the 32 bit and 64 bit versions of Java. I have all of my setting in minecraft set to low (after following someone's instructions on a previous forum.)

My problem is that I'm trying to play Direwolf20 1.6.4 and I get a fluxuating fps 4 to 24. I have the allocated memory in ftb set to 2gb though it says i'm not using that much. It crashes at least once everytime I open it up and my movements are super lagged. I would really appreciate some help with this. Ive been told that optifire (or whatever) and FPSplus don't do anything and might not help at all.

Edit: Agrarian skies works super well... So I'll be playing that while I wait for a reply. Thank you

Hmm...maybe disable the Hats and Hats rack mod? It doesn't impact the game much besides give you silly hats to put on, it may be a source of your lag. It was a kind of problem when I messed with the modpack.

Make sure the launcher is loading only the 64-bit Java install. If it doesn't, you'll have some lag and other issues.

Try creating a new world on your main pack to check FPS. If it's better than your main world, that normally indicates corrupted chunks.

On a new world I'm getting about the same fps as the last but no lower than 4, with varients of 24 (while looking at the sky)

2gb RAM is what you want to play FTB at if that doesn't solve anything chances are there is a laggy mod making the lag.

removing 32 java doesn't do anything. I have the same problem. I have a laptop with 8 GB and I'm not entirely sold the launcher slider for ram allocation does anything. everything runs fine on a computer with 2GB ram. No matter what happens, I get good times then it just shits out on me for 10 secs and then its fine again. Alot of times making it unplayable...

why do you have 32-bit and 64-bit at the same time. Also please up the jab argument to 256 (my go to perm size for modded). And put the ram allocation on the launcher to 1.5 Gigs

most browsers aren't 64 bit and if you go to install java 7, it will default to 32 bit unless you manually install 64 bit.

I'm not sure.. I've only played agrarian skies and direwolf20. I tried BloodnBones but the fps was so bad I didn't even try to fix it, just went back to agarian. I'm trying Direwolf20 because my friend wants to stream a server eventually and I would like to be apart of it.
