I just installed FTB-mindcrack that has gregtech in it and ran into a little odd problem.
The first thing I noticed was a "lag" in NEI, which was noticed as I opened chests, furnaces, project tables, machinery etc. The game would drop insanely in performance for a second or so. Searching for an item in NEI would be delayed, you typed in the word and then it would just do nothing(no lag or anything, just a delay) for a few seconds and then show the item.
I was going through the addons, disabling some to try figure out what addon would cause this. I would disable one addon, play the game, then enable it and disable another and so forth. When I got to gregtech... it was clear this was the addon causing the problems with NEI. Disabling gregtech would cause the search in NEI to be instant, like it was before I installed FTB-mindcrack. I would get no lag at all opening inventories, furnaces, project tables etc.
Can someone please tell me what is going on and a possible way to fix it? I thought at first it was the amount of addons but my other modpack has 54 mods and does not have this problem. With mindcrack I have 60 mods, where gregtech and extrabees are the only ones that actually "adds" a lot of new blocks. The funny thing is that with gregtech enabled I have 17 pages in NEI(depending on the resolution of course). Without it I have 19 pages showing up, so one would think that gregtech would improve performance in NEI - not cripple it?
Anyways... just thought I should post this unless it has been brought up before. With gregtech enabled, NEI lags, even when searching for items, without gregtech... no lag or delayed search.
