FPS chunk lag

Title: FPS chunk lag

Version: 3.0.3/3.0.4

OS: Windows Vista 64x

Java Version: Java 7 (up to date)

Description of Problem:

Tekkit / Technic both have serious lag issues in certain chunks. It's client side as which chunks cause extreme lag shuffle every time I restart my client. Closing the client and reloading when in a lagging chunk usually causes it to not be a lagging chunk when relogging. It's not a computer performance issue or computer specific issue. A lot of people from different servers I play on have experienced the same problem. Information i've found points towards the way Minecraft calculates lighting. This may be the case here, I have no idea as the only Fix for that currently doesn't work with Minecraft forge.

I haven't found any consolidated information on this topic anywhere in my search, so I post what I have found along with the problem here.

Just wondering if Tekkit is going to incorporate some kind of fix for this issue or if they are even aware of it.

Well this is to be expected when going to new chunks but you can check your performance setting in option and lower them. Also if you still have problems, clear your cache.
