AMD FreeSync Technology eliminates one of the major problems in working together monitor and graphics card. Due to some technical inconsistencies update monitor screen does not match the frequency of the output graphics images, resulting in image distortion. However, due to FreeSync of twitches and breaks frames can be forgotten, and at the same time, the technology has the same flexibility as VSync.
AMD designed FreeSync as an open standard, which is compatible with the DisplayPort standard. Unlike NVIDIA G-Sync, FreeSync is not a proprietary technology, and therefore it is much more common in recent years. Currently in Europe, manufacturers offer 105 monitors FreeSync, while the number of monitors with support for G-Sync is only 34 models. Nevertheless, both technologies have their place. In addition, G-Sync will only work with NVIDIA graphics cards and AMD graphics card owners have to buy monitors supporting FreeSync.
In the past few months, AMD has significantly improved functionality FreeSync. First, there is support for synchronization via HDMI, as well as support for HDR, then followed by the introduction LFC (Low Framerate Compensation). The latter algorithm does not allow FPS to sink below a certain level. In addition, for increasing the frequency FPS same frame several times without the need for further rendering can be output.
With the release of Radeon Software Crimson ReLive Edition adds support Fullscreen Borderless Window, HDR10 and Dolby Vision. In addition, Tone Mapping was performed on GPU, instead of a monitor, which should reduce delay. This is true for all the cards on the Polaris, as well as for future GPU.
Now, AMD is going to bring a new level FreeSync and even closer to the ideal representation of the image. In FreeSync 2 support HDR, as well as the Low Framerate Compensation will be mandatory.
But what exactly is a manufacturer wants to change? Let’s look at how the video card and monitor with support for HDR. Rendering and Tone Mapping is done, of course, on the GPU. However, after the withdrawal of the image on the monitor comes another Tone Mapping, to correlate the image with the display capabilities. Performing the same operation twice leads to unnecessary delays. When using FreeSync 2 will be only one Tone Mapping on the GPU. Of course, the monitor needs to support a new synchronization technology.
It is important to note that this mode will only work with games and applications for photo and video. Under the Windows desktop will not change anything and Tone Mapping will be carried out on the monitor. At least until such time as Microsoft does not provide the proper software support.
Currently information about FreeSync 2 quite a bit. AMD will release it later. Monitors supporting FreeSync 2 offers twice the color space compared to sRGB. In addition, Low Framerate Compensation is always active.
The first monitors with support FreeSync 2 will appear, probably in the summer of 2017. All video cards that support FreeSync, will also support FreeSync 2. The new technology will not be part of the high standard Adaptive Sync. Currently a manufacturer cooperates with DisplayPort Group. However, whether FreeSync 2 only work with DisplayPort 1.3 / 1.4 or HDMI 2.0 will also support, is currently unknown.
