[1.6.4] Frame drop to 1~5 when open inventory.

[ghost]

Well , when I open my inventory my fps drops SO MUCH! . And the cause of it is NEI , because when I disable NEI I dont lag anymore. For this reason I'm using Craft Guide , but this mod is bad because dont show all the recipes . Waiting for your guys help !

@SrPandaBr Can you send a screeshot when the inventory is open and the fps dropped?

I'm getting the same issue but with 1.7.10. And it happens when I open the GUI of anything, a furnace, crafting table, machines etc. Rapidly opening and closing the inventory with NEI enabled causes the FPS to dip lower and lower until it hits 1-4 FPS. Disabling it (within' the NEI options screen) and the lag spikes stop.

If it helps, this pops up on my console every time a GUI is opened:

@aking4125 Sometimes this happens because of items being rendered on the screen. This tends to happen when render a lots of animated items or fluid containers with dynamics textures (eg. Extra utilities' drums). This is the case? A screenshot would be nice too.

[aking4125]

Even when the search box (The UI that shows all the blocks and items) is disabled, meaning it doesn't show any items or I press "O" to hide it. The lag still happens, so I don't know what type of screen shot you want to show the lag happening but I can try a .GIF but I don't think that would help as the .gif itself would be very laggy anyways.
