Ok, it appears he did change how the application works.

Apparently (from what I can tell) if you DO NOT have OpenCL support, his program refuses to give DirectCompute results. Upon installing the Stream 2.0 SDK from AMDs site, it is now generating DirectCompute results. IMO that is the wrong way to do it, if a GPU supports DirectCompute (like the 4000 series with 9.12 drivers) then generate a DirectCompute Score. If it supports OpenCL (such as the Stream 2.0 SDK from AMD) then generate OpenCL Scores. Do not limit the program by ignoring DirectCompute scores because it doesn't support OpenCL (they are two different things).

i7-920, overclocked to 4Ghz.

ATI 4890 Toxic, overclocked to Atomic speeds (slight bump in core frequency).

I doubt it, at least not exclusively.

DirectCompute Benchmark 0.35: Generates a DirectCompute Score without a problem.

DirectCompute Benchmark 0.45b: Refuses to generate a DirectCompute Score.

How exactly is that "On my end"?

Because it works for others with .45 and ati...

edit: nvm

Results for version 0.45b:

NVIDIA GeForce 9800 GT @ 1753 MHz (10DE / 614 / 23721682)

Intel® Core2 Quad CPU Q6600 @ 2.40GHz (4 logical CPUs)

Benchmark version: v0.45

DirectCompute: D864.7

OpenCL: C603.2

CPU: M39.7

NVIDIA Windows Kernel Mode Driver, Version 195.62

nvlddmkm 8.17.11.9562

Windows 7 x64 Ultimate Edition (build 7600)

Doesn't look that bad for a two year old system. (the 9800 GT is really a 8800 GT with the BIOS modded)

I know you have already seen my post on how I fixed the issue, but that statement is too general IMO. Just because a program works for others, doesn't mean its going to work normally for everyone. Thats like saying no program in the world contains bugs, any issue someone has is due to their own mistake.

Well I was right, your system didn't have something installed causing it to not work :shiftyninja:

Your answer makes sense, I already had the 9.12 hotfix with the stream SDK installed before i benchmarked 0.45 so I didn't notice that.

Odd thing is, I too installed the 9.12 hotfix (I checked my driver version with the 9.12 hotfix driver version and its an exact match), but I did not have the Stream SDK installed. Its possible I selected to not install it though, if it was possible. When I install the drivers I prefer to go with the bare minimum (I do not install the HDMI audio, as I do not use HDMI, etc).

ViperAFK, we were both right. The author of DirectCompute Benchmark DID change something which prevents the program from using DirectCompute if you are missing OpenCL, that was a "feature" not there in previous versions of DCB. At the same time, you were right in saying it was something with my setup.

What I think is more interesting is WDDM 2.0 and whether it will be coming in Windows 8 or Windows 9 - that will be when directcompute and other features start showing some major leap forwards in terms of the GPU being put to some major use. I hope we'll start seeing some vendors utilise it to speed up video compression speed.

The Stream SDK isn't included with the drivers, you have to install it seperately to get the OpenCL component (stupid I know) but I would imagine that the OpenCL component will probably be included in future driver releases

Well people have already written lots of CUDA enabled encoders, they'll eventually move to OpenCL (yay for multi-platform) or DirectCompute (yay for Windows only!)

Sorry, I'm a bit out of the loop; is there a h264/mp4/aac encoder that takes advantage of directcompute?
