Phoronix: Sandy Bridge Gets Layered Rendering, Fixes Longtime Regression

While improvements to Intel's open-source Linux graphics driver that explicitly target Sandy Bridge hardware is rare these days with the Intel OTC crew being busy with Broadwell, Haswell, and Bay Trail, there is an SNB improvement to report this afternoon. A patch-set has emerged for Sandy Bridge to implement layered rendering and in the process it takes care of a long-time OpenGL performance regression...

Better late then never, whatever . I was not infromed that in US my radeon was so much faster then snb even with broken shadows .

What exactly is layered rendering and what does that have to do with the driver?

Driver must implemented those, so following functions in OpenGL apps can behave right & fast

But i guess GS is not there yet for SNB .

wait, SNB stands for son of a beach?

No, it's SaNdy Bridge.
And I'm happy to see this, given that I'm writing this from a Sandy Bridge laptop.

Could be but here it is not . Also here:

I was not infromed that in US...

US here is not Unites States but Unigine Sanctuary .

Thanks for the info. My graphics information has gotten rusty over the years.
