Hey all,

Long time lurker, first time poster. Before school starts in September I was looking to purchase the 2.6ghz/512 gb rmbp model. I've been using FSX since it came out. It works decently on my 2008 mac pro (2x Quad Core 2.8 ghz Xeon) because I can overclock it to about 3.08 ghz using ZDnet overclocker utility. I can get about 60 FPS during cruise, about 15 in a densely populated airport ie LAX with addons, AI traffic, and the PMDG 747.

Anyways, has anyone used FSX on the rmpb using bootcamp? How was your performance, and what settings (resolution, AA, AF, slider settings, etc) did you use? Any 3rd party add-ons? I am anticipating FSX won't run as well as it did on my Mac Pro because FSX is not programmed to take advantage of additional cores. It is a CPU-dependent game and the 650m will not be a bottleneck. I was wondering if only a single core is being utilized by FSX, will turbo boost be of any advantage as well?

Thanks!

I haven't installed FSX on my rMBP simply because I couldn't be bothered finding a way to get the physical disk somehow converted to a ISO to install it.

However I had it on my 2008 MacBook with the old 9400M GPU and it ran fine. I'm very sure the GT 650M can handle it very well. I would choose 1440x900 resolution if I were you.

Would turbo boost technology be of any help running FSX? The extra clock speed on a single core would help immensely.

Turbo boost isn't only for a single core. In the case of the ivy bridge i7s, 3/4 cores can can get an 800MHz boost, 2 can get a 900MHz boost, and 1 can get 1GHz. At least in Windows, all of my cores are typically running at 3.4Ghz (I have the 2.6 model). So you may as well treat it as a 3.4GHz CPU

FSX can use the multiple cores of C2D, iCore, or Xeon CPUs with at least SP1 installed. SP1 enabled FSX to use up to 256 cores, and SP2 enhanced the multicore utilization with load levelling between cores. FSX will primarily use core 0, with the other cores used as required. For instance, taking off from LAX with high settings for AI, scenery, autogen scenery, and surface traffic will cause all cores to be at or near 100%, but flying at 20,000 ft will only utilize core 0. The FSX Acceleration pack contains both SP1 and SP2.

Assuming it's enabled by default in the Mac's firmware, Intel turbo boost should be automatic. The CPU should adjust speed according to load.

Off topic: do you use a joystick with FSX? I couldn't seem to lift off without one.

You're 100% sure to have much, much, lower performance.
win7 gives me a consistent 5.5 rating for graphics under the VM (macbook pro 2012, 13", intel HD4000)

wonder if that is enough for FS, totally unwilling to mess with bootcamp or boot windows.

You're running two OS'es at once, those ressources can't be used for the game. Bootcamp will allow you to use all the comouter's power.
