Graphic lag since patch 2.15

Since the last patch 2.15 I'm having a lot of graphic lag issues. Good King Moogle was dreadful since the day it came back, but now everything else is horrid too. I even had a bluescreen today, when I never had it before. Especially in instances I sometimes can't move my character or rotate my camera. Everything stutters, as if I was in Mor Dhona on prime time packed with people with their chocobos and pets. I can't lower my settings any more (I play without shadows, no effects, even some sounds are disabled), apart from resolution.
I have a HP Pavillion dv7 laptop, ATI Mobility Radeon HD 5650, on Windows 7 (aero disabled), and an extra Zalman cooler.
I haven't changed anything, it just became like this the moment I logged in after the game got patched.
Anyone else experiencing this?

I have the same issue since last patch, a lot of bluescreens in stances.

I have I7 3770, amd hd 7870 on windows 7
