Because it only took 2 years to come up with the final release for PCIe 5.0. It took them over 5 years to finalize 4.0. We are looking at 4 years of PCIe 4.0. We were stuck with 3.0 for 8+ years.
It's not always about how fast the lanes are together. It's about how fast they are apart. Faster lanes can mean less lanes per device. So PCIe 5.0 and 6.0 are going to be a good thing. And we will need them for USB 4.0.
the only thing that'll make a difference there is ACTUAL support, in both the driver & the game. Eventually it'll come back to life, it'll just be a little while until we get there since DX12 is brand new. No ones really setup how to do it yet.
unlike all these deluded fools that think they're getting sli experience as both gpus sit @ ~50% in v-sync. (BUT I APPLIED THE BITS IN THE TOOL IT MUST BE WORKING!) ha.
R.I.P. Zawarudo, may you OC angels' wings in heaven.
