I have an early 2008 mac pro tower. Runs everything on high settings smoothly at 1440 x 900 resolution without Ambient Occlusion. Super smooth with shadows and distance terrain options disabled in the in-game config.
Model Name: Mac Pro
Model Identifier: MacPro3,1
Processor Name: Quad-Core Intel Xeon
Processor Speed: 2.8 GHz
Number Of Processors: 2
Total Number Of Cores: 8
L2 Cache (per processor): 12 MB
Memory: 6 GB
Bus Speed: 1.6 GHz
My wife's got a new imac 27" (http://store.apple.com/us/configure/MC510LL/A?mco=MTg1ODA3Nzg)
which runs it perfectly fine out of the box on average settings, but still has framerate issues in crowded areas. However, she prefers to play in windowed mode most of the time.
^Its actually got the same specs as the imac in Naylia's post. At first it wouldn't start up, kept giving me the error that FFXIV had stopped working at launch. Make sure to re-insert the Snow Leopard CD and install the bootcamp drivers from the same CD that came with the computer. Also, if you have or are planning to have more than 4gb of RAM, install Windows as 64bit. Edited, Sep 18th 2010 6:34am by Traumata
