3D graphics processing
Morphological Anti-Aliansing (MLAA) post-processing has become available since the release of AMD Barts cards. For those of you, who might not know, it is a software anti-aliasing feature using DirectCompute API. One of the main advantages it delivers — high processing rates compared to traditional ways of anti-aliasing. Besides, MLAA can be combined with any other anti-aliasing method:
There is nothing much to write about — it is better to try it your self, yet no one can tell you what results you might get. The thing is, MLAA technology is only two month old and its nearly half-done. AMD works really hard to support and develop MLAA, but comes all in a time. That is, step-by-step, we will get quite an interesting technique, that improves image quality with minimal performance losses.
Enhanced Quality Anti-Aliasing
Two months have passed since the day MLAA was introduced — and here we go again, another anti-aliasing method made for AMD graphic cards. This time it is called Enhanced Quality Anti-Aliasing (EQAA) — something that has been used in NVIDIA graphic cards for a long time now, but with a diffident naming, Coverage Sampling Anti-Aliasing (CSAA).
EQAA mode is easily activated in AMD Catalyst Control panel:
Again, the main quality of a new method is almost negligible usage of graphics card’s resources.
Unlike new ways of Anti-Aliasing, using which AMD managed to avoid significant performance loss at load, tessellation improvements required more drastic approach. As we already have mentioned it in the architecture review, AMD had displayed acumen to increase performance in complex DX11 mode — not only AMD Cayman features next gen. tessellation module, but the number of modules has been doubled. Looking at the tessellation performance increase, AMD deserves no end of praise — AMD Cayman outdoes its predecessors by a head, at least:
Worth to note, finally there is no performance drop when using big (higher than ten) tessellation factor numbers.
