Intel Aims For Open-Source OpenGL 3.0 Driver By Year's End

[AlbertP]

It seems like http://en.wikipedia.org/wiki/Intel_GMA does not contain the hardware support for GL / DX, but the highest version supported by the drivers.

And it was that page where I got my info about GL & DX support.

That's wrong. Ivy Bridge supports DX11 and GL4 in hardware. What you may be referring to is that the Windows OpenGL driver only supports OpenGL 3.1, but that has everything to do with how much effort Intel has put into that driver, and nothing to do with the actual hardware. Sandy Bridge can support the full GL 3.3 as well. I'm not sure about some of their older chips, but I think the G45 is also capable of 3.3.

Yup. Sucks, too. Some Intel IGPs that run full DX10 often only support GL2.0 because Intel hates puppies, kittens, bunnies, and ducklings. Not that OpenGL is used much of anywhere in the first place, but it's just one of the many reasons why anyone outside of spreadsheet-addicted business users are strongly urged to get an NVIDIA or AMD GPU.

G45 aka Eaglelake/Cantiga supports up to OpenGL 2.1 in hardware. You won't get OpenGL 3.0 on this.

Sandy Bridge was the first Intel chipset to support OpenGL 3.1 in hardware. OpenGL 3.2 at Intel will come in 2013 with the release of the Haswell CPU. Yet-to-be-released Ivy Bridge still supports OpenGL 3.1 only.

Why do they claim DX11 then?

According to the official specification, Cantiga/Eaglelake supports DX10. DX11 support is introduced with Ivy Bridge.

Perhaps Microsoft have written some software fallbacks to run DX11 programs on DX10 hardware.

OMG really? I thinked it was OpenGL 3.3 at least

[marek]

DX11 also supports all the DX10 hw.

Yep. We're definitely planning on it.

I love you. I just wanted to say that. I love you.

That's very good news. I hope that they continue working on GLSL after that, since that's the major problem with OpenGL 3.0 - 3.3.

Yep. We're definitely planning on it.
