AMD Demonstrates "FreeSync"

Pa, nije bas ni sjajno. Linus je izbacio video sa CES-a i Freesync se gasi ispod 40Hz iliti FPS i javlja se manji tearing, a dolazi i do flickering-a.:zgran: Nadam se da to moze da se ispravi. Valjda je do panela nesto, a ne do same tehnologije, ako sam dobro razumio.
 
Meni se dopada sto je standard otvoren i sto nema dodatnog hardvera ali je ovo sto su prikazali realno je krs. Ne radi ispod 30/40 fps kao ni preko 60/144 fps. Na UHD monitorima radi od 40-60 fps sto je bezveze. Ispod se javlja tearing, iznad isto ili ne ako upalis i vscync ali onda imas lag. Mozda nije do tehnologije vec do implementacije, ali ja ovo ne bi platio ni dinar ekstra.

Verovatno hoce, pre ili nesto malo kasnije. Ako FreeSync monitori steknu popularnost i omasove se, nece biti svrhe da ne podrze, samo bi sebi na stetu radili.

Zavisi valjda od panela, tj. koji je minimalni refresh rate koji panel podrzava. Postavlja se pitanje sta kada FPS padne ispod minimalnog refresh rate-a? Tada bi trebalo da se jave odredjeni problemi sa prikazom. NVIDIA je valjda isto imala taj problem sa G-Sync-om, ali su nasli odredjeno resenje i algoritam da se to premosti. Ocigledno je da AMD js uvek nema odgovarajuce resenje za ovaj problem.

Nemoguce je da radi (makar ne perfektno) kada je FPS veci od max refresh rate-a, jer je jednostavno monitor tu limitirajuci faktor, tj. refresh rate ne moze da dobaci do FPS-a.
Ono sto mi se svidja kod FreeSync-a je sto ukoliko FPS prebaci max refresh rate, ostavlja se mogucnost izbora V-Sync on ili off, dok je kod G-Sync-a tu automatski scenario slican kao V-Sync on, tj. nema tearing-a, ali se javlja odredjeni lag. Istina, uvek se moze postaviti max FPS cap, ali je uvek lepse imati izbor.
Po meni je takodje bezveze uzimati monitor (FreeSync ili G-Sync) koji ide do 60 Hz, jer naprosto sama ta Sync tehnologija radi u veoma suzenom FPS okviru, van koga se dobijaju te odredjene nuspojave.

Tehnologija je odlicna i postace standard. Sve vise ce biti brzih panela, za koju godinu ce svaki igracki monitor imati 144Hz i onda ova tehnologija apsolutno ima smisla. Ovo je jos u povoju i ne treba razmisljati sta moze sada da nam pruzi vec koliko jos moze da nam pruzi u buducnosti ;)

AMD Promises 11 FreeSync Monitors by March, 20 in 2015 – 120Hz IPS Asus MG279Q

http://wccftech.com/amd-11-freesync-monitors-march/

Asus’s 120Hz 2560×1440 IPS MG279Q Supports FreeSync

According to AMD, FreeSync branded monitors require certification which is handled directly by AMD. The certification process is done by AMD for any monitor maker free of charge. In addition, AMD also stated that FreeSync will still work on any adaptive-sync compatible monitor even if it was uncertified. The company will still offer full FreeSync support through the display drivers. This is as long as the monitor supports the DisplayPort 1.2a Adaptive-Sync VESA standard.

It turns out the MG279Q from Asus falls into this category. The monitor does support the Adaptive-Sync VESA standard however it is yet to be FreeSync certified by AMD. It’s still unclear whether Asus intends to have the monitor FreeSync certified in the coming months or not. But either way users should rest assured that they can still enjoy the benefits of FreeSync on any Adaptive-Sync enabled monitor.

Pa to je pravi posao, 120Hz, taman 2 osvezavanja frejmu kao minimum ili 120fps-a za vrhunac igranja ;)
 
asus rece 599 dolarjev,ako ispostuju i ovde ne preteraju sa cifrom bice mu tesko odoleti.
 
Mogu da zamislim sto bi sada bila lepa cena da to ima kod nas da se kupi :(
 
Lep monitor ovaj Acer XG270HU. Uvek se iznenadim kolika je razlika između 60Hz monitora i 144Hz. Prosto prevlačenje kursora po ekranu, skrolovanje, minimiziranje/maximiziranje prozora, prosto imaš taj gladak ko puter osećaj, kao da si upgradeovao konfu i da radi brže :D U praksi freesync stvarno eliminiše cepanje i štucanje u igrama, samo bezveze što moja R9 280X nije podržana pa su mi dali R9 290X da bih testirao. Fino sve to deluje u praksi, uživancija za igranje.

Gde se nalazis da dodjem da ga ukradem :D

Znaci ne verujem, potpuno istog misa i podlogu imamo :D
 
Kad mozemo ocekivati opis?
i zanima me kolka ce biti cena u nasim prodavnicama...
 
Sigurno će biti "povoljna".
 
***nje, pomesao sam ovaj model sa XB modelom koji ima IPS panel...
 
A ja se javljam za GoT na engleskom :d
 
Gde ste uzeli ove got knjige, deluju kvalitetno? Gledao u Vulkanu, sve neke stampane na toalet papiru.

Verujem da ima dosta ljudi sa G5, moj furam već osmu godinu, neuništiv je :) Podloga je isto toliko stara, i ona se ekstra drži, teflon se nije uopšte izgulio iako sam čitao da nekome jeste. GoT knjige mi je kupila devojka preko KP od nekog lika koji ih dobija, na engleskom su ipak u svom izvornom jeziku.

FreeSync je super stvar inače, baš me zanima kakav će biti ovaj Asus MG279Q sa IPS panelom.

Ovo je TN panel ?
1440p i 144hz 27" ima bas pristojnu cenu ... kada ce doci kod nas ?
 
Jel zna neko preko kog madjara na kp mogu uzeti neki od ovih monitora? posto vidim da se uglavnom bave televizorima...
ako moze neki kontakt na PP, bio bi zahvalan.
 
Citao sam da je 24" optimalna velicina za gaming monitor. Jel to vazi za 1080p pa ako je veca rezolucija onda moze i veca dijagonala?
 
Malo starija vest, ali nisam video da je neko postovao... AMD Demonstrates FreeSync-over-HDMI Concept Hardware at Computex 2015

Sprema se jos jedan ASUS monitor - Asus MG278Q (27", 1440p, TN, 144Hz, FreeSync): Asus MG278Q TN Film Gaming Screen with FreeSync
To bi trebala da bude FreeSync verzija vec postojeceg ASUS ROG Swift PG278Q (G-Sync) monitora.

ASUS ce po meni imati definitivno najbolju ponudu sto se tice 27", 1440p, 144Hz, TN/IPS, FreeSync/G-Sync monitora.

TN:
ASUS MG278Q (FreeSync)
ASUS PG278Q (G-Sync)

IPS:
ASUS MG279Q (FreeSync)
ASUS PG279Q (G-Sync)
 
 
Izgleda da su pronašli rešenje za do sada jedan od najvećih minusa u odnosu na gsync.

FreeSync Low Framerate Compensation – LFC

One of the most exciting new features that’s debuting with Crimson is FreeSync Low Framerate Compensation or LFC for short. Before we discuss what LFC does and why it’s a huge deal for FreeSync let’s take a step back to explain what FreeSync is.

Project FreeSync is an AMD initiative which initially kicked off back in 2013 with the vision to bring variable refresh rate monitors to market through industry standards and by working with established ASIC and monitor manufacturers. AMD proposed the Adaptive-Sync standard in 2014 to the VESA body and it has since been adopted and incorporated into DisplayPort1.2a. Interestingly, AMD also revealed to us that they’re working on implementing FreeSync via HDMI.



There are tremendous benefits to employing a variable refresh rate for gaming applications, something which we’ve discussed at length on numerous occasions. Suffice to say that we’re huge fans of variable refresh technologies, including FreeSync.

AMD’s efforts quickly came to fruition this year as we witnessed a flood of new FreeSync monitors come to market. Despite the fact that G-Sync had arrived to market a year earlier than FreeSync, we’ve so far seen considerably more FreeSync monitors come out than we have seen for Nvidia’s G-Sync. Partially thanks to the open standard nature of FreeSync and partially thanks to the significant cost advantage associated with the technology for both manufacturers and end-users.

Back in May of this year we took an in-depth look at variable refresh technologies and why they were such an important developmental breakthrough for PC gaming. We analyzed and compared both technologies from AMD and Nvidia & gave our take on the pros and cons of each.

When we looked at how the two technologies – namely FreeSync & G-Sync behaved – we found identical behaviors at large with one notable exception and that is what happens below the variable refresh rate window, LFC plays a crucial role here.

If we have two identical monitors with identical minimum and maximum refresh rates, let’s say 30-144Hz, with the only difference being that one features G-Sync and the other features FreeSync. G-Sync & FreeSync would behave differently when the game’s framerate dips below the minimum threshold which is 30 frames per second. The FreeSync monitor would revert back to being a fixed refresh rate monitor running at 144Hz. With G-Sync on the other hand the variable refresh rate functionality extends below the minimum refresh rate & this is achieved through frame duplication.




Here’s an example. If the framerate dips down to 25 frames per second (which means that it would last for 40ms on the screen) a 30-144Hz monitor simply can’t go down to 25Hz to match the framerate due to issues associated with brightness and pixel longevity. So instead G-Sync would display the same frame twice at a rate of 50Hz/50 FPS ( each frame lasting for 20ms for a combined total for both frames of 40ms ). This circumvents the limitations imposed by the minimum refresh rate of the monitor by allowing the same frame to be displayed on the screen twice really quickly, instead of once quite slowly. This applies for all framerates below the minimum refresh rate. So if for example the framerate dips down to 12.5 FPS, the frame in this instance would be displayed four times ( 20ms + 20ms + 20ms + 20ms )

This provides an experience that’s identical to a panel that’s capable of going down to 25Hz. The only downside to this technique is that it can cause a perceptible change in brightness on some panels i.e. flickering. So it’s certainly not a perfect solution but it’s still a viable and considerably better alternative to simply reverting back to a fixed refresh rate which would introduce considerable latency.

Low Framerate Compensation introduces this clever functionality to FreeSync, effectively extending FreeSync functionality below the minimum refresh rate. It’s worthy of note that while AMD did not expressly divulge its “secret sauce” so to say of how exactly LFC works due to competitive reasons, we were still given sufficient hints to indicate that it follows a similar frame duplication technique to what we’ve seen with G-Sync.

This feature is compatible with any FreeSync monitor featuring a maximum refresh rate that’s 2.5X greater than its minimum. So it will be available on all 144Hz FreeSync monitors and the Asus MG278Q which operates at 35-90Hz with FreeSync enabled.
