Company of Heroes Goes DirectX 10

Post by Apoptosis » Sat Jun 02, 2007 7:37 am

This past week THQ Inc. released a patch adding Microsoft DirectX 10 support to PC game title Company of Heroes. This makes Company of Heroes is the first commercially available DirectX 10 Windows PC game and we have been busy benchmarking it over the last couple days to bring you some performance numbers on the latest and greatest DX10 video cards from both ATI and NVIDIA.

I had to really study the first picture to tell teh difference between DX9 and DX10. Is there that much improvement everywhere else? ^_^

Interesting to see the performace graphs, a nice slope of power!

Here is something interesting I just found out looking at the shader clocks...

The shader clocks on the two 768MB GDDR3 GeForce 8 Series cards are...

8800 Ultra - 1667 MHz
8800 GTX - 1350 MHz

The difference in the shader clocks between the Ultra and the GTX is 23.5%....

At 1600x1200 the difference in performance is 27% with no AA and 20% with 4X AA.... If you average those two scores the average performance improvement is 23.5%...

Average performance improvement at 16x12 is 23.5% and the shader clock difference is 23.5% --- To me it is interesting to that upcoming game titles won't be CPU limited or even GPU limited... "Shader Limited" looks like a term we might start to see more often. I mean what are the chances that this came out to the same percentage..

Are these settings overclockable? :)

What's the Shader clock frequency on the ATI?
Just a little puppy trying to make it in a big digital world.

yes you can adjust the shader clock...

The Radeon HD 2900 XT has 320 'processing units' that operate at a clock speed of 742MHz.

Any chance of some screenshots showing the difference between CSAA on nVidia and MSAA on ati?

Thanks guys, very well done. And now I have a great link to show my bud who thinks clocking the "OC-warrantied" EVGA 8800GTX's isn't worth his time. :D

The ATI Radeon 2900XT used the CATALYST 7.5 drivers that were released on May 31st, 2007 and all three of the NVIDIA cards used Forceware 145.45 drivers that were also released on May 31st, 2007. "
Just got an warranty OC'd Ultra so glad the extra shader performance will help in DX10 games. I do hope these numbers improve for both ATI and Nvidia cards though :|

Good article but Why you guys always take the 8800 GTS 640MB with GTX, Ultra and HD2900XT to make benchmark, There is 8600GT, GTS, 8800 GTS 320MB too. I would like to see them in the benchmark to compared to the HD2900XT

srgess,

Those just happened to be the cards that I have on the test bench. That review was done prior to my leaving for Taiwan... So it was also done on a short time frame as I had a plane to catch! I'll be here (in taiwan) for 8 days to cover Computex and then visit some factories in mainland China.

Hope you all enjoyed this article... I spent my time doing that instead of packing like I should have!

Oh in those circontance, yeah you had no choice. But up to now i didnt saw any dx10 benchmark of 8500, 8600 series. It was more a sugestion to be the first to do it :-)

thats pretty sad, i would like to see how the 8600s do vs those games, whats the point of putting out a dx10 card like that if it cant even play dx10 at any decent FPS

Maybe this time software is ahead of hardware?

Also, nVidia GeForce 8 (non-8800) doesn't do very well in anything. Even if it has DX10 support, I don't think you would get playable framerates considering an overclocked 8800 Ultra can't even score 60 FPS in not-so-high resolution (1280x1024). I know the tests we're done with highest graphical options but still, a 800$ should, in my opinion, be doing better than that. Especially that one of the main reasons behind G80 is DX10.

Friend of mine went from an 8800GTX to an 8600GTS and pretty much gave up on F.E.A.R. Needless to say, he's back on the 88. :D

srgess,

Let's just say NVIDIA didn't even send us an 8500 series card and no AIB partners have sent us one or even offered us one. That just goes to show that the performance is nothing to write home about. Brian Wallace the video card guru here on LR has the 8600GT and the 8600 GTS and is an avid player of CoH, so maybe in the future he will include some DX10 numbers for all to see. The 8600GTS shouldn't be too bad I wouldn't think at resolutions under 16x12

Any chance of CSAA vs regular AA screenshots?
