60fps but still lag spikes?

[TheMrsomedude456]

Hi, I recently got the sphax texture pack (128x) for FTB ultimate and I am getting a solid 60fps with Vsync but every 15 seconds I get a lag spike. My world is fairly new and I only have A pulverizer and powered furnace setup so it can't be machines.

I dedicated 8gb of RAM to it. I have added Optifine (I don't need it for fps, I use it for the connected textures and better grass etc.) and I also have added Damage indicators mod as it got taken out of Ultimate.

So is there a fix for this or do I have to go back to the default texture pack.

PC Specs If it helps:
i7 860
GTS 250
8gb RAM

I'd recommend maybe dedicating less RAM to it, maybe try half what you are (4GB), as (insert long boring explanation here) you shouldn't dedicate your systems entire amount of RAM. Secondly just try disabling Optifine and see if this makes a difference, if it does then I'd recommend trying a different version of Optifine (lite, standard or ultimate) and see if that improves it.

Also a strange one that works for some people, try muting the sound and see if that improves anything.

If none of these work then it might be worth posting your logs when you have one of these spikes so we can take a look at it for you.

it may also be the leaking worlds issue mine does the exact same thing

Use less RAM. Feed the Beast only needs around 1.5 GB of RAM. You are using all of your RAM for Feed the Beast making the entire computer run slower. Computers need room to do they're own thing.
