Hmm...I've tried all sorts of configurations today and I can't get it workingNot that I am aware of. As I recall all I did was simply setup passthrough and add the 480 to the VM. Its a windows 10 VM if that matters.
Vmware 6.5, 6.0U2, 6.0U1
Windows 10/8/7 hosts in both 64 and 32 bit variants
Vsphere client vs web client - there is a bug in the 6.0 web interface that does not handle PCI devices well
I think I might have to try a different brand card and see if that helps.
Or it might be the motherboard...which would be unfortunate
