Okay, here's a bit of a problem that I've been having lately...I'm out in my world, mining, building, exploring ect... but then seemingly out of no where, massive lag. either I'll be in my base (where there are about 5 machines and a very small sorting system) or I'll be down in my mines, when it happens. I'm not sure on how long I've been in game when it happens, however. But, here's what happens; there will be 2-4 seconds where I can't do anything, its almost as if the whole PC has locked up, however it isn't. Trying the MC instance to respond to commands in the 1-2 seconds that its not lagging has been really annoying. I can still alt-tab out of the MC window, so I know that its not the computer that has locked up, just massive lag in-game.
I've removed journey map and have the opis map running, which did help at first, but now the problem has returned. Here's my specs and such:
OS: Windows 7 Pro (x64)
RAM: 8GB DDR3, 4GB dedicated to the FTB launcher
Processor: AMD FX 8350 8 core @ 4 GHZ
GFX card:Geforce 550-ti
No JAVA arguments from the launcher are set (including the fast computers one, that seemed to have no effect)
Any ideas?
