Hexxit Choppyness

[Alex25]

Whenever I play Hexxit, the game is always so choppy, even though I'm getting 60-130 fps most of the time. Anyone else having problems like this? I've searched everywhere. Didn't find anything.

Specs:

AMD Raedon 7850

AMD 8-Core FX-8120 Zambezi

16 Gigs of ram

Is my computer the reason?

Increase PermGen using the gear in the top right of the launcher. I keep hearing 2-3GBs is the best memory setting.

There's a source of hidden lag that doesn't crash Java, here's the fix and a sample error log.

My Minecraft video settings: Graphics Fast, Smooth Lighting Off, Max FPS, View Bobbing Off, Adv OpenGL On

When exploring a new area avoid combat until you have circled the battlezone, so no chunks are being generated during the fight.

Turn on Advanced OpenGL if it isn't already on.

Thanks guys. I'm not sure what helped but I took all your advice and the game is working much better, thanks!
