The PS4 doesn't support more than 60 Hz output and TVs don't support more than 60 Hz input (yes, even those claiming 120, 240, 480 or 600 or even 800 Hz and so on). That's where the problem is, because if the PS4 renders a frame more than those 60 per second this frame is not send to the TV, the scene skips that frame ahead without it ever being displayed.

On a 120Hz Tv that frame is still missing, but what these TVs do is calculate an additional intermediate frame between two (and 240 might calculate 3 intermediates, or 1 intermediates and do a black frame between each frame). That might dampen the effect of the frame(s) missing. Yet be aware that this frame calculation is adding in input lag, as the TV _needs_ to wait for input frames to calculate the intermediates (and that takes time again), which is why usually this is "off" if you put TVs into "game mode".

That's the sort of reasoning I was expecting. But if a TV has a lag-free processor it could recreate the intermediate frames... I mean we are talking here about GSync Nvidia tech, righ?

Massive difference and running over 60fps... the hater will haters more and more... EPIC.

And GAF was right again when somebody said...

"IW took 3 weeks to port CoD to PS4 in 1080p running at 90fps without optimizations"

DAT PS4 power.

Is this a new in-joke I'm not aware of?

Exactly. Like above a fps limit (like 90fps), the vsync engine can't cope and everything becomes hell!

Anyway from feedbacks everywhere, people do not notice any stutter anymore after the patch and the framerate drops are really occasionnal (like in a cinematic or during auto-save sometimes). And it is perfectly smooth during MP: the gameplay is never compromised.

And finally, some people find 1080p COD more pretty and sharp than for instance 900p AC4.

Oh lol, I forgot about that. I know it's fake, but still pretty funny.

Fixed. Although, now that I think about it, for comedic value alone, I maybe should have left it as is. ;)

Update from DF, finally the anormal judder has well been fixed by the patch and we just have some regular framerate drops.

Recent DF tweet about COD Ghost patch:
We're pretty sure now that this isn't an issue in the patched version where stutter does come from dropped frames.

Stealth update in Eurogamer article:
Update: Having reviewed the patch captures, there's an odd issue with tearing which caused some confusion, but we're fairly convinced now that in the revised version of the game at least, any judder is down to frame-rate drops and not the game running faster than 60Hz.

So what was the point of this wholly negative article published 2 days before now and stealth updated just now? The night of the X1 release. O wait!

What a mess.
