We asked Richard Huddy, Worldwide Developer Relations Manager of AMD's Graphics Products Group, to go into more detail about why the Radeon HD 2000-series architecture has been optimised for shader-based AA rather than traditional multi-sample AA. He told us that 'with the most recent generations of games we've seen an emphasis on shader complexity (mostly more maths) with less of the overall processing time spent on the final part of the rendering process which is "the AA resolve". The resolve still needs to happen, but it's becoming a smaller and smaller part of the overall load. Add to that the fact that HDR rendering requires a non-linear AA resolve and you can see that the old fashioned linear AA resolve hardware is becoming less and less significant.' Huddy also explained that traditional AA 'doesn't work correctly [in games with] HDR because pixel brightness is non-linear in HDR rendering.'

While many reviews of the HD 2900XT have made unflattering comparisons between it and Nvidia's GeForce 8800-series, Huddy was upbeat about AMD's new chip. 'Even at high resolutions, geometry aliasing is a growing problem that can only really be addressed by shader-based anti-aliasing. You'll see that there is a trend of reducing importance for the standard linear AA resolve operation, and growing importance for custom resolves and shader-based AA. For all these reasons we've focused our hardware efforts on shader horsepower rather than the older fixed-function operations. That's why we have so much more pure floating point horsepower in the HD 2900XT GPU than NVIDIA has in its 8800 cards... There's more value in a future-proof design such as ours because it focuses on problems of increasing importance, rather than on problems of diminishing importance."

mozna za zdrzenim stoji vydani Cat 7.5beta nekde sem uz na ne videl linky ale sam sem je jeste neskousel pockam si na ofico zatim problemy s hrama nemam takze to nehrotim.

zjednodušeně podle ATi nemá klasické AA budoucnost a bude využíváno čím dál méně naúkor AA přes shadery, které by asi R600 mělo zvládat mnohem lépe, než G80 ... klasika ... je tam též něco o tom, že současné AA nefunguje korektně s HDR
aj spík ingliš not vel

No tak tusim sa to stymi new drivermi odost zlepsilo.Potesilo ma to lebo uz mam tu kartu objednanu.

uz si skousel taktovat?

jinak taky planujes na ni hodit HR-03 az se vyresi ten medenej plisek na vypodlozeni na jadro? podle me ji pak uchladim v pohode pod 70°C s nakym 120mm pomalobeznym vetrakem
