Hi Guys, just installed (and deleted immediately :apple:) windows to test the new SteamVR tool.
This tool calculates if your machine is ready for the upcoming Oculus Rift.

My setup:
iMac 27" (late 2015)
Core i7 (6700k) / m395x
512GB SSD / 32gb (1600mhz)
** freshly installed bootcamp because steamvr is only available on winblows (64bit version)

as a compare, i asked someone to do the same test on his PC
Windows 10
i7 (5820k) / 32gb
GTX980Ti

I think apple really has to step up their GPU game..

Problem is that Apple uses mobile graphic card chips instead of desktop class. Mobile graphic card chips will always be less powerful than desktop class chips (e.g. compare 980M to the regular GTX 980). But I do agree that Apple should use better mobile graphic card chips (impossible to use desktop class with the design of the iMac). But even a 980M isn't that great for VR. Remember the 980 Ti can cost above $500 for the card alone.
 
A couple quick clarifications.

Steam VR is different from Occulus Rift. Occulus has their own test and it will say "no" to every Mac in production.

There is a MXM 980M that is full spec, ie, just as fast as reference GTX980. Apple could use better GPUs, they just don't want to.
