Need to reduce the lag when you go to loot something. Frequently there's a 1-2 second gap where frame rates go to shit. This didn't used to happy, and I suspect there's something funky going on in TBC. Happens especially when looting in combat.

I assume there would be performance gains in using Item Types instead of specific items for the filters, yeah? Like just check to see if something is a recipe, not if it matches a specific ID?

Works!
