sourceWithout CrossFire, apps and games running on the Mac Pro must be custom written to take advantage of the two GPUs. According to AnandTech, Apple has configured the Mac Pro so that "by default, one GPU is setup for display duties while the other is used exclusively for GPU compute workloads."
The site noted that "it is up to the game developer to recognize and split rendering across both GPUs, which no one is doing at present," and that, "unfortunately firing up two instances of a 3D workload won't load balance across the two GPUs by default."
Thanks for posting @agentflizzo. Can you give a little more detail.
Thanks for the clarification.I didn't have to turn off multi-threading. I simply changed 24 to 12 and ESO started and has run very well. I get the occasional crash to desktop, but otherwise all is working as I'd expect for a brand new MMO.

Interesting to know. They don't say it wont work just that it is unsupported currently. I'm not sure myself why some will and some wont with the same game.Works fine on my dual-CPU Mac Pro. No tweaks at all.
