ATI 2900 Pixel Shader 4.0, Geometry Shader and Vertech Texture seems to be 20-200% lower under DX10 / Vista.

Awesome,i hope crysis run just like that.

You and me both hope...but I doubt it :)

Kinda unbelievable though. Many factors may reason why the 2900 XT didn't perform. Perhaps the shader compiler isn't working for the application

My guess is that the card just plain suck. I would know since i have one @ my table :p

Well I do not know, since I do not have one :)

I like my 8800 GTX right now, even though I only game on WinXP and DX9

meh show some games where it counts

Those tests show what we already know about the R600. Comparatively weaker texturing rates along with weaker texture filtering. Those high math ops tests and some of the pixel shader tests are clearly limited by AMD's drivers though. It also highlights one of the obstacles the driver teams face with the R600 as it needs to have a high level of compiler optimizations in place for those shader ops else it gets abysmal performance.

The parrallax mapping tests really show that the G8x cards are very proficient at pixel shading. Vertex Texture Fetch is used on such things as instancing and True Parallax mapping at the vertex level. It's also interesting that from other synthetic tests, the G8x is more proficient at Dynamic Branching than their AMD counterparts. Something which was far weaker in previous Nvidia GPU's.

Is there a download of RightMark DX10 available? (couldn't get their link to work)

Oh it's working now

You need to have referer enabled to download.

Nice to finally see a true DX10 benchmark.

Oh please, name me a ground up DX10 game that we can test on right now.

There's something very fishy in this DX10 reincarnation of D3DRM. :bleh:

well there are a few dx10 games although they are just dx9 with extra dx10 effects... something doesnt seem right about this benchmark... how can the 2900xt be so bad?

i mean in that test its beating the 8800GTX... but here it gets owned but not by 200%:

Call of Juarez is kind of a joke. NVIDIA called foul on it.

As a matter of fact, from all of the shy patched DX10 games/engines, only CoJ have the most noticeable DX10 features added, not just more hi-res textures.

And runs with visual artifacts on one of the said cards. Thus making a comparison impossible

The fact remains that Xx900 is not what ATI/AMD touted to be. And no amount
of spin is going to change that

BTW, why do you think xbit D3DRM tests are fishy, but are happy w/ COJ ones?

its just that i cant believe the 2900 would be over 2x slower than the 8800... i never trust synthetic benchmarks... hope crysis or ut3 show a better comparison

But according to NVIDIA, DX10 was poorly implemented in Call of Juarez. Even though the 2900 XT beat it in that test, the full version of the game's benchmark actually showed the 8800 Ultra and 8800 GTX beating the 2900 XT if I remember correctly. Performance was pretty much abysmal on all of them. Techland responded by saying it's our game and we can make it run as poorly as we want. The game looks like absolutely nothing special and yet it runs so badly. Clearly they didn't even attempt to optimize it for today's hardware (well they claim they did for ATI, but it's certainly nothing for them to brag about). They probably just did it as a novelty.

yea 22fps at 1920x1200 is terrible... seems nowadays we need to get the best hardware of today to play yesterday's games with all the details and high res... oblivion is a good example... hmm i wonder if i can run chronicles of riddick now with good framerates using softshadows... never tried on my 7950gx2

That was mostly about their objection, considering the use of a software AA resolving in the bench--instead of the less flexible fixed-function [but faster] one--which is a standard (mandatory) DX10 feature.

They had other complaints too about the shaders though.

CoJ was a nvidia branded game, then ATI someone got in the picture, mest around with devs, and on purpose made it slower on nvidia hardware. to show off their R600
