Identifying the source of "Can't keep up" error

[AlCapella]

I've found last night that the latest version of NEI (that I was using, not the latest latest) was causing the game to freeze solid, requiring alt-ctrl-del to fix. The latest lastest version wasn't showing anything at all in NEI. Using the recommended seemed to be more stable, but I'm getting rendering errors in the players armour slots.

[sighs loud enough for people around him to be startled]

It's to be expected really, 1.7.10 is still in alpha/beta stage for large number of mods, plus forge is constantly updating. Not exactly a stable environment to build a pack in.

Agreed, and the present track record is not exactly making me optimistic for 1.8 either.

Well in my case the can't keep up error and lag I was having was caused by Biomes O' Plenty. As soon as I removed that I was having no more problems

Bite me, boy wonder.

Ive been getting that error forever. It means lag. The longer you play, the more often the errors pop up. mods that add lots of worldgen such as BoP and Twilight forest seem to make it much worse.
