GFX Issue on MacBook Pro?

Hi all,

been playing since day 1 - and I run D3 on a late 2011 MacBook Pro. The GFX card is a AMD Radeon HD 6750M.

The GFX have never been that great for me but the FPS has always been pretty smooth.... Sometimes the GFX would chop a bit and I would just restart and everything was back to normal.
I have not played for about a month or so... now when I come back I am experiencing major "chop", and a "laggy" feel (ie: the response time on my click is slow and feels "dumb"). It also seems like there is a "rubber band" feel where the FPS is changing from slow to fast.

Is this a known issue? Any suggestions? I want to play d3 again, HELP!!!

Here is a video of it too.


When I join the game I get the usual choppiness, it seems like everything is loading. This has always happened, but it usually goes away within minutes. Right after I fight that first elite and I am killing those tremors, that's the issue I am trying to describe. Hope this helps a little... a month or 2 ago my gameplay was pretty smooth, considering I am playing on a MBP laptop, etc. but now this is just unplayable... and it gets worse the longer I play...

THANKS for your time. Look forward to response...

P.S. the circle around the mouse pointer is something put there by the screen capture software... not sure if its because its a trial version, or whatever..
