For example:


This card (G400-TV) was one I was looking at. They have a full-source
driver availablem but it "does not enable video features". Their
support was open because they didn't want to actually finish or
support their drivers, they just put enough work in to make them
function and left them to rot. No work was put in to increase
performance, support of features, etc.

So the question for all the closed-source haters out there: would you
rather have an open source driver that barely works or a closed source
one that works great right out of the proverbial box?

Sure you *CAN* hack an open source driver to support the things it
doesn't already, but look at that matrox card. It's been years, has it
