It's not as good as Hardware Mode but is worth a try to squeeze out more FPS.įollow me on Twitter The OS X compatible GeForce GTX Titan can be purchased from MacVidCards. There is a utility called 'HyperSLI' that can enable Software Mode. It does not support Virtualization Technology. Yet, the SLI jumper is not recognized on the Mac Pro tower even if you are running Windows. But they do support Scalable Link Interface (SLI) mode. But just be aware that only one GPU will be active - unless the game developers decide to add the code to enable both of them.Īs for legacy Mac Pro tower owners, if you have matching NVIDIA GPU, they don't support CrossFire. If you prefer to run your games under OS X, that's cool. Also, in case you don't know it, CrossFire mode is not supported by OS X - yet. We 'cherry picked' the two above to make our point. Not all Windows apps benefit from CrossFire mode.

They don't run under OS X - yet - but they were certainly 'pumped up' with CrossFire enabled. We chose a pair of AMD R9 270s for our tower experiment. The Windows AMD Catalyst Manager lets to enable and disable CrossFire mode without having to reboot. On the other hand, the AMD GPUs in the Mac Pro towers require the CrossFire cable connecting the matching pair. The AMD FirePro pair that ships in each 2013 Mac Pro is already physically CrossFired. It should be clear from the graphs above that if you are a hard core gamer running Windows in your 2013 Mac Pro's Boot Camp partition, you can use the CrossFire mode to 'fuse' the dual FirePro GPUs so the game treats them as one really fast GPU.

Posted Thursday, January 23rd, 2014 by rob-ART morgan, mad scientistĭid you know that if you boot Windows on your 2013 Mac Pro, you can run the dual GPUs in CrossFire mode? The OWC Lab ran some tests for us on a two new Mac Pros running Windows 8.1.
