FreeSync FAQFAQ

Virtually all monitors feature circuitry known as a “scaler,” which governs the interaction between the graphics card and the physical LCD panel. This essential circuitry also provides user-facing features like: audio output capabilities, display interfaces (e.g. DisplayPort™ or HDMI®), and the “OSD” (settings menu). AMDhas recently entered collaboration​​ with the industry’s largest scaler vendors (MStar, Novatek and Realtek) to create a range of monitor scalers ready for DisplayPort™ Adaptive-Sync by year end; these scalers will pave the way for retail monitor designs that offer compatibility with AMD’s Project FreeSync in 1Q15.​​

Mantle Frequently Asked QuestionsFAQ

As Mantle is the first low-overhead PC graphics API built by and for game developers, it has seen significant traction within that community. As of September 23, 2014, 95 developers have registered to work with the Mantle SDK in our ongoing private beta program. Of that group, 10 developers have publicly committed support for Mantle across 20+ games and four game engines. The most recent games include Battlefield™ Hardline, Dragon Age™: Inquisition and Sid Meier’s Civilization®: Beyond Earth™. Altogether, the first-year adoption rate for Mantle, measured by shipping games, is on-track to exceed that of DirectX® 11 in its first year of availability.

FreeSync FAQFAQ

Project FreeSync will utilize DisplayPort Adaptive-Sync protocols to enable dynamic refresh rates for video playback, gaming and power-saving scenarios. 

All AMD Radeon™ graphics cards in the AMD Radeon™ HD 7000, HD 8000, R7 or R9 Series will support Project FreeSync for video playback and power-saving purposes. The AMD Radeon™ R9 295X2, 290X, R9 290, R9 285, R7 260X and R7 260 GPUs additionally feature updated display controllers that will support dynamic refresh rates during gaming.

AMD APUs codenamed "Kaveri," "Kabini," "Temash," "Beema" and "Mullins" also feature the necessary hardware capabilities to enable dynamic refresh rates for video playback, gaming and power-saving purposes. All products must be connected to a display that supports DisplayPort Adaptive-Sync.

It is our current understanding that the software architecture of select games may not be compatible with dynamic refresh rate technology like Project FreeSync. In these instances, users will be able to toggle the activation of FreeSync in the AMD Catalyst™​ driver.

FreeSync FAQFAQ

The basic benefit of Project FreeSync is the dynamic refresh rate ("DRR"), which allows the graphics card to synchronize the refresh rate of a monitor 1:1 with the framerate of an AMD Radeon™ GPU. With DRR, gamers can  experience the full range of framerates produced by a graphics card without clamping to some divisor of the monitor’s refresh rate (e.g. 30 or 45 FPS). Because Project FreeSync can eliminate the large jumps in framerates induced by traditional v-sync, the result in noticeably smoother gameplay.

Gamers especially sensitive to input latency — a delay between mouse movement and cursor movement — will also see a distinct increase in responsiveness.

Finally, running a game at full framerates (e.g. without v-sync) would typically introduce nasty horizontal tearing, but Project FreeSync also eliminates tearing as a rule. Project FreeSync is a "best of all worlds" solution from the perspective of smoothness, image quality and responsiveness.

FreeSync FAQFAQ

Project FreeSync is an AMD effort to leverage industry standards, like DisplayPort Adaptive-Sync, to deliver dynamic refresh rates. Dynamic refresh rates synchronize the refresh rate of a compatible monitor to the framerate of a user’s AMD Radeon™ graphics to maximally reduce input latency and reduce or fully eliminate stuttering/juddering/tearing during gaming and video playback.​

FreeSync FAQFAQ

With Project FreeSync, an AMD Radeon™ graphics card directly controls display timings. Direct control eliminates the need for polling or waiting on the display, which could impact latency and performance. ​

Upon connecting a FreeSync-enabled monitor to a compatible AMD Radeon™ graphics card, the minimum and maximum times between the display of new frames (the vblank period) is exposed to the GPU via DisplayPort Adaptive-Sync. Because the minimum/maximum vblank period is known to the graphics card, successive frames will intelligently be sent within those boundaries. Predictive or speculative timing is not required under this model, and the GPU will adjust the display's refresh rate to match the current frame rate.

If an upcoming frame is delivered outside of the monitor's supported vblank period, that frame will be immediately presented on-screen when available to ensure the fastest possible screen update.

FreeSync FAQFAQ

AMD has undertaken efforts to encourage broad adoption for Project "FreeSync", including:

  • Royalty-free licensing for monitor vendors;
  • Open and standardized monitor requirements (e.g. no non-standard display controllers or ASICs);
  • Industry-standard implementation via the DisplayPort Adaptive-Sync amendment to the DisplayPort 1.2a specification; and
  • interoperability with existing monitor technologies.

AMD is presently advocating these benefits to display vendors and working with their respective design teams to expand the capabilities of high-performance/gaming-oriented monitor lineups to include Project FreeSync. While AMD cannot possibly guarantee that "every monitor" will adopt Project FreeSync in time, we do believe that this approach is best to achieve wide industry support.

Additionally, it must be established that all dynamic refresh rate technologies require robust, high-performance LCD panels capable of utilizing a wide range of refresh rates without demonstrating visual artifacts. Such LCD panels naturally cost more to manufacture and validate than less capable panels, which may render dynamic refresh rate technologies economically unviable for especially cost-conscious monitors. Economies of scale and the maturation of dynamic refresh rate technologies could help alleviate this concern and further promote adoption in the future.

FreeSync FAQFAQ

​An AMD Radeon™ graphics card compatible with Project FreeSync uses the DisplayPort™ Adaptive-Sync specification to automatically determine the minimum and maximum refresh rates supported by a dynamic refresh-ready system. Using this approach, no communication must occur to negotiate the time a current frame remains on-screen, or to determine that is safe to send a new frame to the monitor.

By eliminating the need for ongoing communication with pre-negotiated screen update rates, Project FreeSync can execute highly dynamic changes in frame presentation intervals without incurring communications overhead or latency penalties.

FreeSync FAQFAQ

​AMD Radeon™​ graphics cards will support a wide variety of dynamic refresh ranges with Project FreeSync. Using DisplayPort Adaptive-Sync, the graphics card can detect and set an appropriate maximum and minimum refresh rate based on the capabilities reported by the display. Potential ranges include 36-240Hz, 21-144Hz, 17-120Hz and 9-60Hz.

1.02227/29/2014 12:34 PM
  
FreeSync FAQFAQ

Project FreeSync’s ability to synchronize the refresh rate of a display to the framerate of a graphics card can eliminate visual artifacts that many gamers are especially sensitive to: screen tearing, input lag, and stuttering. Project FreeSync aims to accomplish this through an open ecosystem that does not require licensing fees from participants, which encourages broad adoption and low end-user costs.
