Titolo: John Carmack Is Pushing Hard For Asynchronous Time Warp On The PC.

During Oculus Connect 2014, John Carmack took the stage and talked for 
one hour and a half about various topics. The guru programmer talked 
about his relationship with Samsung, solutions for various issues 
present in Oculus Rift’s DK2, the ability to fully enjoy a VR 
experience, as well as the most important result coming from the mobile 
environment that is no other than the asynchronous time warp notion.
 
Asynchronous Time Warp basically gives developers the ability to 
de-couple the refresh rate of a screen from the rendering of the eye 
buffers. Basically, what this means is that a screen will be refreshing 
at your native rates all the time, but the rendering of your game will 
be at a lower FPS. Thus, games will look smooth even while running at – 
say – 30FPS.
 
Obviously, this is not as good as ‘true’ 60FPS but it’s a great 
workaround for all games that suffer from weird and unexplained 
slowdowns. Most importantly, it’s a better solution than frame 
interpolation, as the latter is plagued with input latency issues. It’s 
also a great feature for less powerful GPUs, or for systems that aim to 
offer 4K or Oculus Rift experiences.
 
“Asynchronous Time Warp will allow you to, in theory, have a 30Hz game 
that’s get updated to the screen 60 times per second” said Carmack and 
continued:
 
“So we are trying to get that on the PC for a lot of these things 
because as we start looking at the 90Hz displays and 75Hz at DK2, these 
are hard to hit even on the PC with all that horsepower. And I’ve said 
it many times before and people don’t like to hear it, but the PC costs 
about a factor of 2X in sort of the overhead that you wind up incurring 
when you are dealing with latency, not with bandwidth.”
 
Carmack concluded that it will be really hard to bring Asynchronous 
Time Warp on the PC as all vendors will have to work together and agree 
on implementing such a feature.
 
“There are challenges on the PC so we are deeply engaged with NVIDIA 
and we expect them… there is the whole matrix that we’ll have to work 
through; NVIDIA, AMD, Intel and then PC, Mac and Linux. That’s a lot of 
work to get some of these really twitchy stuff working. The work is on 
going right now and there are varying levels of optimism and despair 
amongst different people in the company about how well this is actually 
going to work out on the PC.”
 
Of course Carmack wants to bring Asynchronous Time Warp for VR gaming 
on the PC, but we don’t see why this feature – in case it does come to 
our platform – won’t be featured in ‘normal’ games as well, especially 
since this will let developers – in the long run – achieve better 
visuals.
 
Naturally, mere words cannot give you a proper idea of what 
Asynchronous Time Warp is all about, so below you can find a video 
showing this technique in full effect.
 
We’ve also included Carmack’s entire speech for all those that want to 
sit back and hear what the programmer guru had to say.

"Messo a diretto confronto con un monitor di alto livello IPS qual �
il NEC MultiSync PA272W e facendo girare uno slide show d'immagini e
filmati ad alta risoluzione, abbiamo fatto parecchia fatica a notare
differenze risibili di colore che riuscissero ad andare oltre la mera
soggettivit�, che ci ha portato a notare qualche tonalit� leggermente
pi� accese da una parte o dall'altra."

Effettivamente... io mi tengo stretto il mio EIZO !

Un affare...ma io prender� quello privo di g-sync e poi doner� la
differenza a nvidia per rendere il mondo un posto migliore.

Probabilmente 600, forse anche un pelo meno dipende dai concorrenti, ma a
120-144hz non sono tantissimi, con g-sync per ora quasi nessuno.

Te ne compro uno!
