What it says is: Used memory: 80% (200mb) of 247mb

Allocated memory: 90% (250mb)

OK guys never mind I've solved this problem (i think - i don't want to jinx it). Thanks for all your help anyways.

What was the fix? I have identical issues

My computer is great so it makes no sense

Win7, 8gb ram, nvidia graphics card

basically brand new

When I played tekkit I was on normal rendering distance, and when the lag kicked in I changed to short but nothing happened. However, when I started the game in short render distance I had no major problems and no lags spikes (although the delay when opening interfaces was still there). I dont know how to fix that yet
