Forum:Random lag spikes

Hi

Been playing tekkit for about a week and in the last few days I've been getting frame lag. It lasts for a few minutes then goes away for a few minutes.

The odd thing is when I change my performance settings, either down or up, the lag goes away for a bit.

My PC has 8 gig of RAm so running the game on 4, and it never seems to use much more than 1, and my graphics card is never running at more than 30%.

I did have a problem with crystal chests causing lag but replaced them all with diamond ones. I've only got 4 teleport pipes, and no world anchors.

Anyone got any idea why it's happening or how to help?
