I don't think PathScale has any intention of creating a generally useful driver for the benefit of the community at large. Specific people may find specific advantages for a limited set of hardware (NV50 or newer), but they seem uninterested in the 3d stack. They then tell us that they're looking to add OpenGL 4 support, which is an extremely dubious claim, even for a big company. What, are they just going to build their own 3d driver from scratch on top of their own custom kernel memory manager? How many people do they have working on this project?

And a compiler company, to do all this? Maybe they should stick with compilers for the CPU. They don't seem to understand how the open source world (or the graphics device driver world, for that matter) works.

But hey, people who want really fast 2d on their new awesome $500 Fermi card can grab pscnv and be amazed at the glorious non-composited desktop (that a $15 Intel chip can do equally well)...
