Hi there - first post, hope I'm not in the wrong place.
I just saw the announcement of OpenGL 3.1 support in the next driver and wondered if that means that OpenGL geometry shaders will finally be supported.
I have a research project that might be very fast on AMD hardware, but I can't run it because of these missing features.
Thanks in advance,
Jon
As far as I know geometry shaders are part of OpenGL 3.2, not OpenGL 3.1.
Yes, geometry shaders are in the core 3.2 spec but are left as an ARB extension for 3.1.
So the question still stands - Will the 3.1 driver support ARB_geometry_shader?
Now that Catalyst 9.8 is out, can anyone confirm/deny ARB_geometry_shader4 support?
I don't have any radeon cards to try it out on myself, but if it's in there, it might be time to buy a card or two for performance profiling.

OpenGL Extensions Viewer 3.14 says that ARB_geometry_shader4 is suported with catalyst 9.8 (running on Windows 7 RTM 64-bit and Radeon HD 3870)

Thanks for the confirmation. I found another post somewhere else saying the same thing, so I picked up a 4850 to test with.
Now the bad news... The extension's there, but I'm getting odd-looking results - as if only the first N triangles ever get rasterized. Anyway, I've posted this problem over on OpenGL.org hoping for more traffic, so that looks like the end of this thread!
