Beyond3D's GT200 GPU and Architecture Analysis

Note that those are slides provided by NVidia. Obviously, no AA enabled in any test. A custom UT3 demo as well, as other tests show far higher framerates.

Also, how optimal do you think the PhysX CPU implementation is?

The medusa demo actually makes good use the geometry shader. And the performance difference between the G92/G80 cards compared to the GTX 260/280 cards is pretty significant.

Is there a document describing the effect? I briefly looked at their web site and didn't see it.

Thanks.

Not that I know of. One of the most obvious geometry shader effects is when Medusa turns the guy into stone. The stone geometry is clearly generated overtop the other geometry.

Semi off-topic, but is the Medusa demo D3D10 or is it done in OpenGL like most nVidia demos?

Look at the improvements when using the PhysX driver:

Also note that NVIDIA is comparing performance between 9800 GTX+ to the HD 4850 in 3DM Vantage. Even without the PhysX driver, 9800 GTX+ has equal or better performance in those slides.

Wtf is going on here. I smell something fishy. I don't think FM will be too happy with the GPU helping out in a CPU test... the tests were specifically designed in order to isolate the CPU.

Well cpu test 2 is designed to measure physics performance. You could say it's of secondary importance if that's run on the cpu or gpu. Of course it doesn't look fair if nvidia gets to accelerate this on the gpu and amd not due to the physics API used. Seems to be the fault of futuremark though rather than nvidia - maybe havok would have been a better choice...
btw I find the hd movide transcode performance graph hilarious. You can clearly see the score going from 1.2Ghz dual-core to 3Ghz quad-core only improves with clock frequency, not core count. My best guess is it's only single-threaded on the cpu, so a properly optimized version would probably be 4 times as fast on the quad-core cpu...

Nah Adrianne was most certainly not impressive. In terms of what we will see in games in a year and a half, I really hope the visuals are a bit better than the Medusa demo. Maybe it's just weak art assets or the cartoony color pallette that are spoiling it for me.

Wow, if Nvidia can release drivers for older cards then they definitely have a winner on their hands.

Although I'm not too excited about another 3DMark-War brewing in the distance, the currently mentioned drivers 177.39 should actually work pretty well on all G8x/G9x GPUs so far (tested for real only on 8800 GTS/512).

That said, I'd rather see some other applications being accelerated than some version of 3DMark.
 
Try UT3?

Remember that you need to update PhysX too.

Carsten, one other thing. Do you know if PhysX works with XP and Vista, or is it just Vista?

I got a GTS 512 and will d/l the driver.

PhysX support is only implemented on the 200 series and the 9800GTX/+ so far I think.

Its planned for the rest of G8x/G9x though.

It will work on all G92 cards with a modified driver. The G80 I'm not so sure about yet. Most of this is a question of time/QA.

I see no reason updating to those drivers. I will when they are released for G80 proper, beta or WHQL.
