I have a 2010 MBP 15" with a i7 CPU and 512MB Nvidia 335 graphics chip. My desktop power supply just died so I tried to hop into WOW on my MBP, and the results were unplayable. I plugged in my display port 23" monitor, and turned ALL settings to the lowest possible setting , and I get 19FPS in WOW. That completely doesn't sound normal to me. I also have this really nasty input lag from my keyboard, when I press anything, theres a second or so delay before anything happens on screen. Anyone know what could be the cause of these issues, or anything to check? Running Lion.
