I have no idea how the PCI SIG works, I simply find it laughable to think that NVIDIA can dictate stuff to the PCI SIG

NVIDIA alone can’t. The PCI-SIG is a traditional tech industry standards grindfest; it doesn’t do anything without the consent of all of the members sitting on the spec’s committee.

Granted, it’s the same Phoenix 2 die, but why use a “specialty” SKU like the Z1 instead of something like the 7440U?

Similarly, I love DF. But I’m not sold on their VR headset reviews due to how little they pay attention to some of the drawbacks of a headset.

Their PSVR2 review from earlier this year didn’t call any attention to how absolutely tiny the sweet spot for that headset is. If it moves even a small amount, you’ll drift out of the sweet spot for the fresnel lenses and get significant chromatic aberration (or worse). It’s distinctly smaller than other VR headsets and quite unforgiving, so it’s something that should have been mentioned. (The fit of the headset is also rubbish for a lot of people, but I can accept that it may not have been an issue for them)
