Hypernetic

No luck, Still lags after i enter.

Hello. I am having a few issues in single-player attack of the b team. Every time I enter my inventory page in single-player, i drop 10-15 frames. That may seem like a minor problem, except that I average at 20 fps . This lag persists about 1-3 minutes after I interact or even open up my inventory. Is there a fix for this problem? I believe it's the mod-pack because in multi-player I have no problem, but only in single-player does this occur. It is really getting annoying, so any help would be appreciated. BTW, I believe I have allocated 2 gigs of RAM and I am currently up to date with the latest 64x version of java.
