DX9 vs Dx10 CPU Overhead with G80

[sargatanas]

ou really need to make this crystal ball of yours a public thing. no one has publicly used DX10 yet, how the hell would you know what it does and does not deliver?

Its also stated the CPU will have less overhead, if the card isn't fast enough, itll still be slow, and chances are with something equivalent to a 9800pro, the cpu would never have been the bottleneck in the first place.

dx10 = agiea ppu

your right there, cpus are going to go the way of the dodo, dedicated processors like the ppu will come into play with dx10+, vista etc

nobody has any proper experience of dx10, we can only sit and wait till something happens.

I agree, I have seen the benchmarks for the PPU and they aren't that impressive. However, I've not seen any DX10 games running in "real life" and have seen no benchmarks either...

I think I'll hold off judgement for a bit. I'd like to think that we will see some performance increases. If everyone took the attitude that newer technology was rubbish and unnecessary then we'd never get anywhere.

You could talk till you are blue in the face to be honest, Some people around here, You see them all the time in threads that talk about DX10 saying the same stuff over and over. It's like a chip on their shoulder.

This basically shows that the GPU is taking most the strain off the CPU, Allowing for the CPU to process other tasks. How can that not be seen as a great advance!?! Simple, Narrowmindedness.

crysis.

crytek themselves say that there is a 20% hit in fps when going from windows xp to windows vista in dx9 mode.

and going from vista dx9 to vista dx10 there is a further 15% performance hit.

Can you post a link to this please?

World Conflict, was developed on Vista and was not so great, most people is over rating DX10, one thing the sound will SUCK on dx10 , you know DX10 does NOT support multichannel, so you will stuck on Stereo, and Creative made a "patch" only for the X-FI series, no solution yet for other sound card
Also the shader 4.0, has only one layer more, I attend to the developers conference from Nvidia, and there are not great new things.
Another thing Intel has not developed new chipsets supporting Vista, so you will have bottleneck, note most i9XX chipset run on a real bandwidth of 9 Gb/s only 3Gb/s more than the i8XX series.The next PCIex will pump 4 Gb/s, but you have another 5Gb/s bandwidth to be shared with System memory,hard drive and Cpu.
Microsoft has pushed to new developing, but as the market is slow, most hardware developers are just waiting, to see how accepted is VISTA.
Here in US, corporate business are not switching to Vista, security still is a issue and there is not substantial gain.

You do realise that you can use a different sound API to Graphics don't you?
