x800 uten ps3.0?

[Robin B]

Fra Cry tek.

 

3.0 shader model is just extension to 2.0 shader model. It means it’s possible to compile PS2.0 shader as PS3.0 shader target and it still remains 2.0 compliant shader from the hardware side. Several new features in 3.0 shader model aren’t for free. Texture access in vertex shader is expensive, dynamic branching is not for free. So if developer has to utilize some features of PS3.0 shader model he/she should design shader in way which will remove other much important bottlenecks of application (CPU limitations, states/shaders changing, make shorter shader execution path, decrease streams bandwidth…).

 

On the event PS1.1 was compared with PS2.0/PS3.0. We don’t use PS3.0 everywhere. The general rule is to use as lower shader version as possible. So PS3.0 could be used only in several critical places where it gives performance boost.

 

In current generation engine quality of PS3.0 is almost the same as PS2.0. PS3.0 is used for performance optimisation purposes.

Eg sei berre! LES ARTIKKELEN!

Det der er bilder som viser kva forskjell som er mellom PS1.1 og PS3.0.

 

Here is what we know, all the screenshots were taken in a CryEngine tech demo. They were not taken from the retail game, FarCry. These were taken as a demonstration to show what the technology is capable of. The first screenshot is running in Pixel Shader 1.1 mode. The second screenshot was taken on a GeForce 6800Ultra video card running in Pixel Shader 3.0 mode with Release 60 series driver and DirectX 9.0c Beta.

 

NVIDIA states that the effects being rendered in the Shader Model 3.0 screenshots are using Displacement Mapping for the walls and stone textures, like the Buddha. They also state that shaders are being used for many of the environmental surfaces and incorporate specular lighting where appropriate. The only effect then that is unique to these screenshots in Shader Model 3.0 is Displacement Mapping; it appears to HardOCP that everything else could be done in Shader Model 2.0.

SM 3.0 og SM 2.0 blir goså sammenlignet.

Ja dei vert samanlikna, men det er vidt forskjellige objekt på bilda så vi kan ikkje sjå den direkte forskjellen. Men må innrømme at eg berre las halve før eg skreiv

Ok nå blir jeg litt forvirra av alle disse forkortelsene. PS og SM og VS? hmmmm

Det er retail versjonen av FarCry og denne PS2.0/3.0 demostrasjonen som er sammenlignet.

VS = Vertex Shader

PS = Pixel Shader

 

SM3= Shader Model 3 (ps3, vs3)

 

og dere som maser frem og tilbake, sjekk denne tråden. alt er nevnt der.

Det der er typisk [H] ... så ALTFOR typisk. Se på vannet på det bildet som liksom skal forstille PS1.1 .. ligner det på vann laget med PixelShader overhodet? Nope.. med PS1.1 så er det ikke noe problem å lage vann som ser realistisk ut. Se bare på Nature-testen på 3dmark01. Det er Pixelshader1.1

 

Jeg hadde aldri i livet turt å diskutere noe på et forum utifra noe jeg har lest på THG eller [H]. Det er ikke akkurat de rette plassene å hente fakta på. Snarer tvert imot.
