Phoronix: Gallium3D Support For Stream Out Arrives
On the same-day as publishing new Gallium3D benchmarks of the ATI R300g driver, we have more Gallium3D news to share. Zack Rusin has just announced a new Gallium3D branch that provides support for "Stream Out" with this advanced graphics driver architecture...

Good to know Zack Rusin has a sense of humor. Hope this is supported on G96 (GeForce 9400M) soon :)
P.S. - First!
So is it going to make Gallium drivers faster?Quote:

No, it's just a mandatory feature in OpenGL 3.0.Quote:

Thanks, I see. This explains why R600+ hardware supports the feature. However, I also noticed from the mailing list that some R300+ hardware can also support it in a limited fashion. Is that going to be too limited to be useful, since these chips are only capable of OpenGL 2.x?Quote:

but you will get hardware acceleration for those operations that hardware can do.
