And now onto my thoughts.... ME:A Marks the first third party game since the release of the PS4pro thats both on the PS4 and PC and that came PS4pro enabled out of the box (so it wasn't patched in). Now while its not representative of the best 4k gaming experience to be had on the PS4pro since its using 1800p checkerboarding while something like horizon is using 2160p checkerboarding. Its still the best we have got for comparison sake.

Now I watched that video in 4k on my 65" HDTV from my sitting distanceof around 7ft (yes I like staying close to my TVs) and unless I am crazy, i could hardly flat out tell the difference between native 4k on the PC and 1800pCR-->4k on the PS4pro. Only in parts where they zoomed in to point out the differences.

Now don't get me wrong, I am not saying there is NO difference, but saying that its really hard to spot.

Which brings me to my point, say we have the PS5/XB2. Both coming with around 10-12Tf of GPU power. Which would no doubt be capable of running games at 4k@30fps with relative ease. Wouldn't it be better if sony and MS caps their consoles at 2160pCR and instead improve on whatever tech needed (even if it meant dedicated hardware) to ensure the best possible artifact free checkerboard solution?

That way, they could be running those games at 2160pCR using about 5-6TF of GPU muscle which would allow most games to instead run at 60fps with all that extra muscle. I don't know, looking at that video, I just can't help but feel that aiming for native 4k is a waste of resources when you actually look at just how close to it CBR brings us.

It does look good on the Pro, and after watching it on my 4K TV I would also say that it's pretty close to the PC version. However, you mention bumping the GPU to help framerates, and that wouldn't really work that well. Framerates are usually CPU limited, so making the GPU better wouldn't do much to help framerates. Though, I think the PS5 and whatever the new Xbox is called should have the CPU grunt to run a decent number of games at 4k/60 fps anyways.



Bet with Adamblaziken:

I bet that on launch the Nintendo Switch will have no built in in-game voice chat. He bets that it will. The winner gets six months of avatar control over the other user.

Thats the thing though.... if you took a game that was running at 30fps but was already maxing out the CPU. A 30-40% boost in CPU power could get the game running at 60fps if the GPU is not a bottleneck.

But on the GPU side of things, you need a much bigger boost in power to go from 30fps to 60fps.

Another thing to consider is that when it comes to the CPU, not all tasks need to resolve at a 16ms (for 60fps) render time, but with the GPU you have to resolve all its tasks at 16ms or less if you intend on hitting 60fps.



contrary to elitist belief, 4K is not the next big innovation in computer entertainment. it is meant to be an enhancement for people using much larger screens and wanting better video clarity. when we made the jump and make HD television the standard over CRT screens, there was a major update to video quality. things became completely digital, quality did not degrade, it was redefined entirely. 4K is just an expansion on HD. it isnt groundbreaking to any degree, its just a step up from what we already have.

that being said, 4K will one day become the new industry standard, it is inevitable. people crave bigger things, especially numbers. and hearing about a new screen resolution with 4 times the amount of pixels as usual will spread like wildfire once it really becomes mainstream. the normies wont know why its good, but bigger is better right?

and now that being said, i really dont have anything against 4K, i just think its being a bit forced and will be more relevant in a year or two. just enjoy what we have now. HD aint broke yet



Something is wrong with your Horizon res. 2160p is 4K, which is 3840x2160 for TVs. You sure it's not also running 1800pCR?

Anyway, for the PS4 I'm expecting a Ryzen 1700 and a Vega 10, which is a 12.5 Tflops GPU, with 8GB of HBM2 for games and 1-2 GB DRR4 for the OS. I'm sure both chips will be slightly downclocked to help with heat, so we're probably looking at a ~11-12 Tflops machine. I think that should definitely be enough for a decent graphical boost from this gen, but in 4K. I still think devs will use 1800p2160pCR if they want to push visuals even more.

Edit: Or am I misinterpreting you?  Are you saying that Horizon uses checkerboarding to get to 2160p and ME:A uses it to achieve 1800P?  Cause if so, that is pathetic for ME:A.

Horizon was originally meant to run at 1800p checkerboard but Guerilla menaged to hit 2160p checkerboard. Digital Foundry Has great analysis of this.

Yea, I think I misinterpreted him.  Thought he meant it was rendering at 2160 natviely, then using checkerboarding to go higher.

Yh you read me wrong.. but to help you out in case you dont know?

1080p= 1920 x 1080 = 2M pixels

1800p= 3200 x 1800 = 5.7M pixels
1800cCBR= 3200 x 900 = 2.8M pixels

2160p = 3840 x 2160 = 8.2M pixels
2160pCBR = 3840 x 1080  = 4.1M pixels

2160pCBR is what was used in Horizon. No 'upscaling" is needed in this case. With ME:A, they checkerboarded to get the resolution to 1800p. Then upscaled that to 4k. 



It may look somewhat close to the PC's 4K native resolution but there are drops in framerates that fall below 25FPS.

In my opinion that is unacceptable for a 'Pro' console.

I think the 'Pro' should have a focus more on fluid gameplay and less on checker boarded/upscaled resolutions that no body understands but everyone loves to tout.

those framerate drops isn't what this is about.... and in all honesty says more about Bioware than it does about the PS4pro. Just look at horizon for proof.

Now your second part of your post is exactly what I am talking about, but more geared towards the next gen. Come next gen 4k would have become mainstream and would be the default resolution of the next gen consoles. I am suggesting that rather than push for native 4k and leave us with a reinactment of this current gen; they should instead push for checkerboard 4k which uses about half the power of what native 4k would have used and use the rest of the power to push for 60fps gaming instead.
