Morphological AA 

Morphological anti-alising is compatible with DirectX 9-11 graphics, and is accelerated by DirectCompute. The Radeon HD 6000 series has this feature, which makes the anti-alising processing much faster, compared to SSA (Super-sampling anti-alising).

 

It works by sending a picture to the part of the GPU that takes care of morphological anti-alising, and the picture is checked for jagged edges and patterns. Instead of processing the normal anti-alising procedures, where the geometry is corrected with slow calculations, the colors are bleached. In this way, the jagged edges are faded, and the graphics becomes more smooth. Morphological anti-alising can fix the whole image, and not just the edges.

 

In high resolutions, rumor has it that the morphological anti-alising should look the nicest, whereas the traditional SSA anti-alising does a better job at low resolutions. But it all about trying the different options, and observe the results. We are just happy of being given more opportunities.

 

Catalyst Control Center lets the user activate morphological anti-alising under the 3D options. 

 

 

   
HD3D gaming

AMD is ready with an alternative to NVIDIA’s 3D Vision technology – AMD HD3D.

 

NVIDIA are strict when it comes to their 3D Vision technology, which requires specific monitors and 3D glasses. The driver is also NVIDIA’s own. AMD goes the other way, and let hardware producers and third-part software developers develop AMD-compatible solutions. This means lower prices, and a bigger flexibility for the user.

 

AMD’s middleware partners iZ3D (I see 3D) and DDD (TriDef) are taking care of the development of drivers for gaming. 3D-player partners, like for example Cyberlink, takes care of the development of PowerDVD with 3D support.

 

LG, Samsung, CMI and Viewsonic are developing 3D compatible monitors (120 Hz), while Bit Cauldron, Xpand and RealD make the glasses. AMD are welcoming more software developers into the community, so the competition is strengthened. By that, the products are getting better and cheaper.

 

Software has to be downloaded from iZ3D/TriDef and be configured, before the ultimate 3D experience can be enjoyed. 

 

 

 

At this time, the iZ3D and TriDef's 3D-software is compatble with more than 400 game titles.

 

 

Eyefinity

The Radeon HD 6800 series' Eyefinity feature has been updated, so it is possible to connect up to six monitors per card. 

 

NVIDIA's Surround feature more disadvantages compared to AMD's Eyefinity. For example does it require three monitors and two NIVIDIA based cards in SLI, which makes the solution expensive.

 

 

AMD's referencedesign has the following connection possibilites:

 

 

  • 2x Mini DisplayPort 1.2
  • 1x HDMI 1.4a
  • 2x Dual-link DVI

 

 

 

DisplayPort 1.2 gives the Eyefinity user a big advantage, since every connection can support three monitors with an adaptor, which is sold separately. Future monitors will have both DisplayPort 1.2 in- and outputs, so the primary screen is connected to the monitor, and the other monitors are chained together. That means, that the Radeon HD 6800 series can support up to six monitors per card, without an adaptor, if the correct, and probably very expensive monitors are used. 

 

 

 

Today’s requirements to the bandwidth are not a problem, since DisplayPort 1.2 doubles the DisplayPort 1.1 standard bandwidth to 17 Gbit/s. That is enough to support following monitors with the following resolutions: 3 x (1920 x 1080 @ 60 Hz) or 2 x (2560 x 1600 @ 60 Hz). DisplayPort 1.2 is sufficient to run 3D in 2560 x 1600 @ 120 Hz.

 

The HDMI 1.4a connection is 3D compatible and is used in multimedia like 3D-TV and Blu-Ray players. In comparison to the earlier HDMI 1.3a standard, the HDMI 1.4a standard gives the possibility of Internet access and huge resolutions (4096 x 2160 @ 24 Hz or 3840 x 2160 @ 24 Hz).
