Specs: Late 2013 15" Macbook Pro with Intel Iris Pro, and NVIDIA GT750M 16GB Ram and i7 2.3GHz Has anyone experienced very poor graphics performance since updating to Yosemite? I've included two screenshots showing worse performance using the GT750M than the Intel Iris Pro on the same machine. These screenshots, however, don't do justice. In practice, when I play games like Diablo 3 and WoW, the GT750M not only gives worse FPS than the Iris Pro, but the GT750M has extremely dramatic FPS spikes when nothing on the screen has changed to any significant degree. Lately, I've been using gfxCardStatus to set my system to use my Integrated rather than Dedicated to get somewhat usable performance. I regret buying the machine with the dedicated GPU. Is anyone else experiencing this?
