G'day All, I have a Macbook pro 13" Mid 2012 CU I7 2.9 Ghz, that I have just installed 16 gb Ram and a 500 Gb SSD. I have been trying to run a couple of flight simulators on the machine and the performance is somewhat of a stop start affair. As though the processor has to catch up on the aircraft. I use this for keeping current in aviation, so I'm not phased about having a high performance flow, so much as the concepts and realism. That said, it would be great to have a smoother experience. My question is, with the addition of the RAM and SSD, is it the graphics card or the CPU that is slowing the simulation down? Thanks for your time!
