hi all, ive recently just got a retina mbp it has 16gb ram ssd (obviously) the upgraded 2.6ghz i7 and a nvidia GT650M My first question is that the activity monitor shows 1 core... should it not be 4 physical (8 logical) ?? and secondly, this computer kicks the c*** out of my old laptop spec wise but it can't run games for anything, e.g., counter strike source ran well on my old MBP 13" with the HD3000 chipset! (onboard graphics) high setting 70 odd fps (more than enough) on this new MBP all lowest settings it struggles to hit 40 and a lot of the time -30 and is almost impossible on online play (laggy as hell) seriously, even on like 800 x 500... so is there something seriously wrong? because this should really surly not be happening. i also tried guild wars 2, MAX settings 22 fps..... MINIMIUM settings... 22 fps.... how can this be?? p.s. i tried lots of different resolutions in both games which did not help at all in some cases. thanks all for any help or advise you can offer!
