Comment about graphics engine upgrade with today's patch is incorrect.
Check www.everquestlive.com
They have an article about needing to upgrade to directx 9.0 for the (and they state clearly) future graphics upgrade which is expected to go live in a month or two. Not with Feb. 10th patch.
Oh, and rumor has it that Tunare 3.0 (the new graphics engine) is supposed to clear up many lag problems and reduce zoning time greatly, even for lowend users (if their gfx cards support DX9 - which if it doesn't they can get 50-75 dollars off a new nVidia gfx card thanks to SOE). On top of also looking pretty.
