lol. While there is overhead in running split CPU/GPU and memory pools. It's clear that with enough brute force there are advantages as well
Seriously, maybe having them locked/VSYNC at typical consumer TV resolutions and refresh-rates (4K/60) was more important.
120fps is new territory for consoles here. So we're see new types of data points we haven't seen before.
We have seen games go above 4K =P and DSR back down to 4K. Wish they considered that, because ti's clear both consoles are clearing 4K fairly easily.
