Interesting. Intel must be getting worried that they are the only chip company without a GPGPU.

Always great to see a fellow Kiwi (New Zealander) get international recognition:

NASA's cool eight screen Google Earth viewer: http://open.nasa.gov/blog/2011/09/26/nasas-liquid-galaxy-an-overview/
Seems similar to Equalizer.
I wonder how these systems compare to AMD Eyefinity or NVIDIA Surround when running multiple GPUs with a large number of screens.

What began as a side project has gone global after a New Zealand student's software was picked up by Google and NASA.
"I never expected it to take off like this," said University of Waikato student Paul Hunkin.
"It started off as little afternoon project and it's gotten reasonably popular."
Hunkin might downplay his success, but NASA called the software an "innovative solution".

Hmm it seems AMD has done their usual trick of messing up their downloads. All of AMD APP files are now corrupted or missing!

Hi Stefan,
The AMD website says you also need to install these 'extra' files to enable OpenCL 1.2:

http://developer.amd.com/Downloads/opencl1d2_additional_files.zip

Cool I will download this and try it out.
Glad to see they are now using LLVM.
Both AMD and Intel use LLVM for OpenCL so we should get consistency between how the compilers interpret OpenCL code.

It is the new extension that RAGE uses for sync, hence why it is listed as a bug fix. NVIDIA have supported this since driver version 280.18 (which is why RAGE runs a lot better on NVIDIA).
It is called WGL_EXT_swap_control_tear. Basically it will vsync if your FPS >= 60, and start tearing if FPS < 60. This is the same behaviour games have been using on consoles for years but had never been exposed on PC before (despite the hardware being there).
Rumor has it you set wglSwapIntervalEXT to a negative number like -1 to activate it.
It would have been better if RAGE fell back to 'normal' vsync if this extension is not listed, but for some reason it doesn't (and you get horrible tearing). You can set r_swapInterval in the config file for RAGE to get around this.
JeGX, perhaps you can test it out in your demos?

I read that the Apple A5 chip in the iPad 2 (and presumably the iPhone 5) has similar performance to NVIDIA's Kal-El which means NVIDIA will need to catch up again when iPad 3 is released.

3D-Tech News Around The Web / Re: EQAA Modes for AMD 6900 Series Graphics Cards
« on: September 16, 2011, 04:22:05 AM »
Just as I though this is a AMD "clone" of CSAA, just compare how EQAA and CSAA work:
http://developer.amd.com/sdks/radeon/assets/EQAA%20Modes%20for%20AMD%20HD%206900%20Series%20Cards.pdf
vs
http://developer.download.nvidia.com/assets/gamedev/docs/CSAA_Tutorial.pdf
Even the DX9/10/11 API commands to set the various modes use identical values to the equivalent CSAA modes.
But AMD don't (yet) support CSAA/EQAA 32x which NVIDIA supports since Fermi. Perhaps the AMD 7000 series will support it.
Here is a handy table comparing NVIDIA and AMD's names for the different modes:
JeGX:
Does Kombuster correctly detect/use EQAA? I don't have a 69XX card to test it on. You will likely need to add 2f4x since NVIDIA doesn't support that. Also AMD uses different names...
