DirectCompute (Direct3D11 Compute Shaders)

Cool, thanks! Hopefully nvidia releases CS enabled drivers for Notebooks in the meantime, so I can finally give DX11 a shot.

 

Is this what you were looking for ?

So once again...there's no public driver with compute shader support.

 

Even if they made this driver public the new stuff is only supported for DX11 hardware.

The plan is to release this very shortly after the official Windows 7 start.

I know this problem with the 3 (3.5 as we although support 10.1) APIs very well as I had it too. Just keep in mind that you would need Vista SP2 to install the DX11 update. If you can force your customer to use SP2 there is now reason to keep DX10. We had already very good results for performances and compatibility with the DX11 beta runtime.

 

It has been just released. See the updated KB page http://support.microsoft.com/?scid=kb;en-us;971644&x=9&y=6

 

Any word on Compute Shader 4.x support on ATI HD(2/)3/4 cards?
As far as I know, 9.10's didn't add it at least

 

Buy an HD5000, then you'll get DC support.
Or is there another reason for this?

 

Not going to happen AFAIK, due to architectural limitations.

 

Asking on behalf of someone.

Err, isn't 4.1 specificly built for the HD3/4 Radeons aka 10.1 hardware?
Or are you suggesting it's there just for kicks while nothing supports it (excluding possibly the couple lowend DX10.1 nV chips)?

 

There are no technical limitations for HD4000&CS 4.1.

HD2000/HD3000 lack CS support and do not have shared memory, so no DirectCompute and OpenCL for them.

 

One would think that it was quite clear that my post only made reference to HD2/3 series...Or did you all assume that I took the time to quote that specific snippet just for the lulz? I know that everything is motivated by the quest for lulz, but still

 

Actually there should be no technical limitation for HD 4600/4700/4800 but lower-end derivatives (HD 4500/4300) lack the shared memory.

 

Srykthxbye.

 

Wow, why did ati do this? I am guessing its a 3xxx series card they have been telling everyone is a 4xxx... This is the type of stupid shit ati has been doing lately, no dp for 57xx series probably none for the low end cards either. Why even have dp on any of the cards if they are going to leave it out of the mid and low range cards?

 

Somehow HD4500/4300 support OpenCL and are based on RV7xx, about the shared memory for OpenCL:

I'm pluzzed, why RV670 doesn't support OpenCL...

Wasn't the local memory mandatory for OpenCL?

 

Yes, but in theory it can be "simulated" using global memory if there are no serious restrictions on global memory access patterns. Although this can be pretty slow.

 

What use is DPFP on entry level boards? It will either add cost, or reduce performance for the same cost. Right now there is no market drivers for it in mainstram and entry level. Higher end product will be used more extensively in the computing space and other business divisions have more specific requirements for it so it makes sense to offer it there.

 

Thanks for the statement!

Sounds a bit like you could insert almost anything there instead of DPFP without altering the sense too much. What use was DX10-Support (which wasn't free from a perf/mm² either) in HD2400 for example?
