Mac client needs to be reborn..? :(

[Avenger]

There are aspects of the thread process scheduling for program parallelization that can be tuned by the Windows version that cannot be tuned by the Mac version. Due to this, situations arise where performance will not be elicited for portions of the game’s parallelization processing and the processing time for frames will be unstable.

Having some experience with parallel programming on the Mac as well as other platforms, I'm a bit puzzled by this, since the Mac has nice instruction and data parallel programming support via Grand Central Dispatch and OpenCL. Moreover, thread priority can certainly be adjusted, and real-time scheduling is also supported.
