Geometry Shaders / OpenGL 3.2 Finally Comes To Intel Sandy Bridge

[przemoli]

My Fermi card supported OpenGL 4.5 within 30 minutes of announcement.

But thanks for your opinion though.

And Mesa supported first extension within few hours...

What that says?

That 4.5 is mostly NV extensions rebranded as ARB, or other older extensions without much modifications.

(That's good news. Maybe we will get 4.2 and then 4.5 in two steps )

Intel is always indirectly making improvements that make their way to unsupported hardware including hardware that isn't even from Intel, it's all good.

False summary! I am using Sandy Bridge on Linux, and I am not ecstatic. Still don't know what I was missing.

How many minutes for Wayland support?

For that I applaud NVidia. It's supporting their product only, not supporting linux. Intel is doing a great job at it, but suck on supporting "legacy" product. It would be nice to see NVidia contribute more tough

That's great support from nVidia, but sorry, Intel is still better at supporting its customers because it gives the source code to the community. I think the reason why Intel's GPU support isn't lasting long is because Intel is still playing catch-up when it comes to graphics so they have to move at a pace faster than competition. I think once they catch up their products will be supported for periods similar to competition.

Also, nVidia has a head start when it comes to OpenGL. I bet Intel GPUs will be ahead of competition in supporting the new API from Khronos.

[asdfblah]

Funny how Intel supports Mesa, but doesn't completely support its own products, isn't it? Anyway, this clearly shows the advantages of open source development...
Also, lol @ nVidia

Well thats nice but how do I actually activate the extension? I've installed latest mesa git and tweaked the gl version override:

MESA_GL_VERSION_OVERRIDE=3.2 MESA_GLSL_VERSION_OVERRIDE=150

but there is no GL_EXT_gpu_shader4 or GL_EXT_geometry_shader4 extension on neither my SNB box nor on my Haswell Laptop.

this is all glxinfo spits out:

Any idea what I'm missing???

That's great support from nVidia, but sorry, Intel is still better at supporting its customers because it gives the source code to the community.

I don't care about source code I care about a working product.

Intel has enough money to make Solomon look like a pauper, I think they can afford to hire a couple guys to provide full support for their products and still have zillions left over in the bank, rather than relying on hand-outs from the "community". What they're doing now is giving out the impression that they are cheap, do not support their products, do not care about quality and do not care about their customers.

It's not just their GPUs either, even after they found that cpufreq / pstates were fundamentally broken they didn't backport any fixes to older architectures.

In terms of software this is basically a third-rate company.

And with their latest TSX debacle maybe they're not so good at hardware either.
