Is any familiar with this? Any bright ideas? I'm not sure what exactly caused this shift. the GPU was at 99%, and I'm not sure about the temp. I then ran atMonitor, which apparently monitors GPU load and temp. Had 93% CPU Idle, 10.5GB free RAM, hardly any disk activity peaks of 1MB/sec. Then, while the game is running, I ran Activity Monitor only to see my system totally chilling. This game used to run just fine until this 'performance drop' occured.Īccording to System Information, when I'm just browsing the internet, my machine is using the Intel HD 4000, and when I run Diablo 3, it then switches to the Geforce GT 650M. I've observed this playing Borderlands 2, under Windows (Bootcamp).

One time it worked, then suddenly it doesn't. When I ran it today, it lags really bad (i.e., running at very low FPS). For example, I've played a lot of Diablo 3 with this computer, under OSX, on standard resolution (not retina), and it played very well, and really smooth. This is best observed in games, running both on OSX and Windows. It's since a couple of days now, that I'm noticing a sharp drop in my rMBP's graphic performance. I've a MacBook Pro with Retina display, running 10.8.2 and Win7 64-bit (via Bootcamp).
