Pixel Shader 2.0 gaming roundup

If Halo, and Splinter Cell : Pandora Tomorrow use PS 2.0, how does XBOX handle those games ? NV2A of XBOX has PS 1.0 does it not ?

Cheers.

NV2A has at least 1.1, possibly up to 1.3? (does it share NV20's or NV25's PS capabilities?)

 

[anaqer]

PS1.1 at the very least, possibly PS1.3 (not sure).

PS1.1 I think, because isn't NV2A just NV20 with two vertex shader units (like NV25 has)?

I think there was bit more than just another VS unit added to NV2A, something which was added to NV25 too.. just can't remember what

just because its on the xbox doesnt mean it has all the same features as the xbox, the devs for the xbox get the luxory of having one hardware set so they can do things not feasible under direct x. why did TRAOD use PS 2.0 ? I mean it was developed for the ps2 so why on earth would it have any pixel shaders at all the ps2 cant handle pixelshaders? The fact is just because a game is made for the xbox doesn't mean it the pc version of it will use the same features. Look at halo for example. Some effects look great at tv rez but have to be done different ways to ge t the same effect at higher rez.

Bungie/Gearbox re-wrote the HALO engine to use PS2.0 , one of the many reasons given for the length of time between the Xbox release and the PC release.

SCT as I think others have said doesn't use PS2.0 ,it's still using the same unreal engine as the first one.

I don't know much about how all this stuff works, but wouldn't it be conceivable to use an engine like the Unreal 2 engine, which is based around DX8, and simply add some PS2.0 effects to certain shaders? The way I've always looked at it, most games require a minimum of DX8, but they recommend DX9, which tells me that maybe there are some DX9 effects used.

Deus Ex2 uses DirectX 8.1 - that's why you can't have the bloom effect and FSAA

What do you mean? I can turn on the bloom effect on DX2, and my GPU (Geforce4 Ti) doesn't even support Pixel Shader 2.0. Are you suggesting that bloom can't be done on a DX8.1 level of hardware?

 

[Laa-Yosh]

He means that you can't have bloom AND antialiasing (called multisampling in the options menu) turned on at the same time. It is a limitation in the API as far as I know.

Ooopppss. Apology to him and you for not reading carefully enough.
