Maybe, because he is also talking about GameWorks VR...
"Nvidia says it can extend that number to 25 million if the VR game makers use Nvidia’s Gameworks VR software, which makes the VR processing more efficient."
But more important... one of my numbers got wrong: GTX980 has to be around 0.80% - 0.90%, not 0.21%. Unfortunately the HW survey is down... preparations for the December numbers?
P.S.: The direct path works... December data! Separated to DX11, DX10, DX9 again, so I have to use my other Excel sheet. ;)
