Geometry Instancing support se ne odnosi na to da od "jednog drveta napraviš šumu" :clap: .
Nego se to trenutno odnosi na podršku za sljedeće ATI drivere i radi se o tome da su se prije UDALJENI djelovi vegetacije radili korištenjem sprajtova a sad će se file-om od par sto kb koristiti Geometry Instancing support.
I to nije nikakav sastavni dio ps3 shadera, a nije bogme ni 1.2 zakrpa za Far Cry donjela pravu podršku ta njih...što su rekli i oni sami, samo je trebalo pročitati.
A "par stotina postotaka" ubrzanja možete samo zamisliti...dajte ljudi promislite malo prije nego kaj nekaj napišete, sve me je sram samo i pomisli kaj bu pomislio netko tko se kuži u grafiku, dođe na PCE i pročita nešto ovakvo...

Shader Model Differences:
Geometry Instancing
Another feature, geometry instancing, could show itself as a noticeable performance increase. With geometry instancing a game could loop information from within the vertex buffer to create the same object. A good example of this would be in an RPG game where you are controlling a large army, and in that scene the characters all look the same. Instead of having to draw each one separately with geometry instancing the video card could simply draw one of them and copy the rest therefore providing a performance increase. No image quality differences would be seen with this feature, it is purely a performance feature.
Here is a similar listing of key features developers enjoy when moving from Vertex Shader Model 2.0 to 3.0.
Shader 2.0 Shader 3.0 Description
Shader length Shader length
256 Instructions 65535 instructions
More instructions allow more detailed character lighting and animation
Dynamic branching
No Yes
Saves performance by skipping animation and calculations on irrelevant vertices
Vertex texture
No
------ Any number of lookups from up to 4 textures
Allows displacement mapping, particle effects
Instancing support
No
Required
Allows many varied objects to be drawn with only a single command

"Another key feature of Shader Model 3.0 is the support for the Microsoft DirectX® Instancing API..."
službeni izvor.Što je ovo?dakako da je dio shadera 3.0!To je dio same specifikacije!Tu ATI nisam ni spominjao, već sam rekao što nvidia ima spremno pod ladicom...Far cry nisam ni spominjao implementira li i kako-već sam rekao kako bi jako mogao profitirati...Tko sad priča gluposti?
Dal vjerovati tebi ili microsoftu?Ipak su oni napravili DX...
Tko se sad smije?
Ovo što ti spominješ nitko nije spominjao, niti sam ja spominjao ikakvu ATIjevu impementaciju niti drivere...Znam da sam nešto tražio, a evo ti sad, ako dođe "netko tko se kuži u grafiku", khm:confused: :clap:
Ma evo ti
fanATIce...
