Or is it just one of Phil's balls in my throat?

i know NEO will be a nice upgrade from PS4. I'm still waiting for information about SATA 3 or full SSD support, and maybe a fucking USB port at the back!
Yeah, I really want news on SATA3

My 1Tb SSHD died a couple months ago and going back to a 5200rpm 500Gb has been rough. Waiting on Neo news to decide what drive to get.

Ah, ok- perceived latency, not actual latency. That makes more sense.
It's actual latency response to head-tracking. "Perceived" is only in so far that you're reprojecting as opposed to rendering in the most accurate pose, but the pose is still actual.

To be more specific - assuming a relatively standard Logic->Render game-pipeline, 60->120hz reprojects ~33/40ms worth of latency.
120->120 reprojects roughly 16.7ms.*

*Both values are before prediction.
 
Really? Multiple-GPUs?

Console launches make people go absolutely bonkers. Why would they go to complicate the design, increase the thermals, and make development harder after creating the PS4 as a lesson learned from the PS3?

Use. Basic. Reason.

Out of curiosity, what's impossible about it?

In Neo mode the APU will be a CPU with co-processors /accelerators Devs will still see it as a Jaguar CPU while Sony can update the functions of these co-processors/accelerators with microcode.

The hype and speculation has gotten pretty crazy, where did the dual GPU speculation come from? I remember contemplating if Sony were going to do that with the original PlayStation 4 release.

Dual GPUs would be possible but may not be very practical, it would also be very expensive and would likely lead to a console that is a lot larger than the original PlayStation 4 to cope with the increased thermal output and additional hardware.
However, the power that would be available to developers would be immense!

You're looking at 8.3 teraflops of processing power from a setup with two 2304 GPU cores clocked at 911MHz, with this level of power your pretty much looking at a true half generational jump in performance, one that could be unfortunately held back by the PlayStation 4.

Sony claims that the PlayStation 4 is 10x more powerful than the PlayStation 3, this system would be around 4.5x more powerful than the PlayStation 4, and with a slight boost in clock-speed 5x more powerful, we're almost in PlayStation 5 territory here, it's insane!

Seeing this kind of power put to use at 1080p would be mind blowing, it would be kind of a wasteful to see this used to push 4K resolutions, but it would be able to do it, and fairly well too.

So, it's re-sampling the headtracking position to complete that just-in-time reprojection pass... ?

It makes even more sense, if that's the case. Thanks.

This thread becomes worse and worse. lol.

Where are all the Gaf leakers?

It isn't just GAF leakers/insiders that are quiet. This PS meeting thing has falling completely flat especially after the slim leak. No announce/hype from Sony and the media seem to have gone silent on the subject (threatened in some way?)

Outside this thread it is like this isn't happening. I'm sure Wednesday will still be great but this build-up sucks. I just hope there isn't any bad news like Neo in 2017.

No it would be 6.29TF if the PS4 APU is clocked at 911MHz like the main GPU but 6.04TF if it's clocked at 800MHz.

Not entirely true. AI doesn't need to do pathfinding twice as often because decisions are made at a different tick rate than animations. Network code is dealing with the same latency and bandwidth so it won't have double the workload. Audio related work is identical to running at 30fps. It's extremely title-dependent ... and none of it is the deciding factor anyway.

Games will be 60fps whenever the developer decides it's important. Period. I don't know how many times something similar needs to be repeated before people will believe it. We had 60fps titles back on game consoles whose CPUs were a fraction of a percent as capable as what we have now.

I was going to start a thread asking this question about fps and how it relates to other game aspects like AI, so thanks for clearing that up.

Also thanks for your endlessly level-headed posts in this thread :)
