But in fact "Blender" is a weight for the open-source driver.
Blender is designed to not support model politics like "FireGL/Quatro" or "Closed source like catalist or the nvidia driver.".
And the "Blender" dudes will never slave them self by adding features to force them to use Quatro/FireGL cards or using closed source drivers.
maybe they are to smart to be a slave.
