With a GTX 760 GTX 970 4GB and 32GB of RAM, would this set up be usable for the rift? essentially its a mac pro with an upgraded graphics card and windows 10 installed, I know the device wont work while booted into Mac OS but would it work in windows? ive got a usb 3 card installed to.
The cpu will work, but I don't know if the vid card has high enough hdmi bandwidth to work. Now as to how good an experience you can expect even if it works, it won't be very good and might make you sick. It's just nowhere near enough video card to push the resolution a rift runs at.
With that cpu I'd pair it with a minimum of a 1060GTX. Even then in cpu limited games you'll have some issues, but most stuff is video card dependent so the slower cpu won't be much of a liability (I'm running an even slower PhenomII x4 955).
So I have run the VR performance test (let me know if this isn't the right one) and a Unigine benchmark on extreme preset. (Screengrab below)
The VR test says it would be compatible but question is what sort of performance would I get out of the machine? Basically would love to get into VR, but I don't want to buy a new machine, so hopefully this system would work, otherwise down the route of PS VR unfortunately.
I was referring to the Oculus one: https://ocul.us/compat-tool This tool will also let you know if you have supported USB 3.0 ports, which are a bigger deal than you might think.
So I've run the oculus tool and now I've got mixed results. Everything is Rift ready apart from the processor, but its seems like the compatibility tool is only seeing the one of the processors, and the Steam VR tool said this processor would be suitable (But its seeming both for some reason). I don't mind buying a new GPU but new processor unfortunately to costly for the Mac Pro.
