The AMD FreeSync 2 Q&A With David Glen & Syed Hussain

The AMD FreeSync 2 Q&A With David Glen & Syed Hussain

AMD is going to expand their royalty-free FreeSync technology this year with the introduction of Radeon FreeSync 2. If you have already read our FreeSync 2 tech briefing earlier, you know that FreeSync 2 promises to offer HDR gaming with minimal input lag.

While waiting for AMD to finalise Radeon FreeSync 2 and its certification program for their partners, let’s share with you our Q&A session with the two key AMD engineers in charge of the Radeon FreeSync 2 project – David Glen and Syed Athar Hussain.

 

The AMD FreeSync 2 Q&A With David Glen & Syed Hussain

AMD Senior Fellow Architect David Glen and AMD Display Domain Fellow Syed Athar Hussain are  the main guys heading the Radeon FreeSync 2 project. In this informal Q&A session held on the last day of the AMD Tech Summit in Sonoma, they give us more details on FreeSync 2.

An interesting point in this Q&A session is how the wide colour gamuts that many monitors support these days are not being utilised at all. Hope you enjoy it. Sorry about the noise though. There seemed to be some interference from nearby devices.

For those who prefer a summary of what they discussed and answered, here are the key takeaways :
  • Radeon FreeSync 2 is an AMD proprietary standard, but they will eventually push for it to be an open standard.[adrotate banner=”4″]
  • Radeon FreeSync 2 is not an AMD Vega-specific technology. It is a backward-compatible technology.
  • All GPUs that support FreeSync will support FreeSync 2, via a driver update.
  • FreeSync 2 will not be part of the Radeon Software Crimson ReLive Edition. It will only be introduced in the following Radeon Software edition.
  • FreeSync 2 will support the FP16 and 2-10-10-10 colour buffer formats, that current AMD Radeon Software drivers already support.
  • The AMD FreeSync 2 API will allow developers to quickly add FreeSync 2 capability to their games and game engines.
  • Games that do not integrate the AMD FreeSync 2 API, or use game engines that support it, will not be able to automatically switch to HDR mode, or use the FreeSync 2 transport.

  • The AMD FreeSync 2 monitor certification program will include stringent requirements for low latency (for native and scaled resolutions) and colour space, with an AMD lab to ensure that those monitors meet the minimum requirements.
  • FreeSync 2 will not deliver the colour space of HDR10 or Dolby Vision, but it’s designed to greatly expand the colour space with minimal input lag.

  • The input lag as specified in the AMD FreeSync 2 specifications is defined as the lag from the display flip to when photons are emitted.
  • There will be two-way communications between the monitor and the graphics card. The monitor’s capabilities are conveyed to the graphics subsystem, and the graphics subsystem will instruct the monitor to go into its “native operation mode” to make full use of its native colour space.
  • FreeSync 2 will support both active (two-dimensional) backlights and global illuminating backlights.

The Radeon FreeSync 2 HDR Gaming Tech Report

We were fortunate to be amongst the few invited to the AMD Tech Summit held in Sonoma, California from December 7-9, 2016. Today, we are finally allowed to reveal the third major technology update from the AMD Tech Summit – Radeon FreeSync 2. AMD also revealed a major feature upgrade to the current FreeSync technology. Get the full details below!

Updated @ 2017-02-06 : Added the AMD Radeon FreeSync 2 Tech Briefing video.

Fullscreen Borderless Windowed Mode Is Here!

AMD fans who have been clamouring for FreeSync to work in windowed mode will be ecstatic to learn that their request has been heard and answered. FreeSync will now work in the fullscreen borderless windowed mode!

So watch out for a driver update to start playing your games in the fullscreen borderless windowed mode very soon!

HDR Gaming

The big story though is Radeon FreeSync 2 and the next killer feature it enables – HDR gaming.

Current monitors are mostly built around the sRGB colour space, which limits the richness and vibrancy of the scene. Colours look dull and washed out, and details are lost in the shadows and highlights.

New HDR transport technologies like HDR10 and Dolby Vision aim to solve this limitation, offering 8X or better perceivable range of the sRGB colour space. They also make much better use of the display’s maximum brightness levels, which are left unused in sRGB mode.

There is a problem with both HDR10 and Dolby Vision though – they are not optimised for gaming. The tone mapping performed by these displays has a long input lag.

This input lag is not a problem for cinematic movies or video clips that render at 24 to 30 fps. However, it will be a problem for gamers who want high frame rates of 60 fps or better. AMD attempts to address both problems through Radeon FreeSync 2.

Introducing Radeon FreeSync 2

Optimised for HDR gaming, Radeon FreeSync 2 is a compromise between the wider colour gamut of HDR10 / Dolby Vision, and the low input lag of sRGB.

It offers a limited HDR colour gamut that is over 2X the perceivable brightness and colour volume of sRGB. The FreeSync 2 game can then tone-map to the display’s native colour space. This allows the monitor to skip the tone mapping step, which greatly reduces the input lag.

For this to work, both the monitor and the game must support FreeSync 2. Here are some characteristics of a FreeSync 2 monitor :

  • Low Framerate Compensation (LFC) is mandatory
  • Low Latency is mandatory
  • The monitor will provide its native characteristics to the game through the FreeSync 2 Transport

For game support, AMD will provide a FreeSync 2 API that will :

  • support the FP16, 2-10-10-10 colour buffer formats
  • automatically switch between sRGB and FreeSync 2 native modes (when a FreeSync 2 game loads)

All AMD Radeon GPUs will support FreeSync 2 via a new driver. However, it won’t be in the recently launched Radeon Software Crimson ReLive Edition.

 

When Will FreeSync 2 Be Available?

AMD will launch Radeon FreeSync 2 in 2017. They are aiming to get it out by the first half of 2017, but there is no firm date yet.

 

Will FreeSync 2 Replace FreeSync?

No, Radeon FreeSync 2 will exist in parallel with FreeSync. FreeSync 2 will merely be a higher standard that offers HDR gaming, on top of stutter- and tear-free gaming.
