    Phoronix: Nouveau NVC0 Enables ARB_post_depth_coverage

    Red Hat's Lyude has enabled the ARB_post_depth_coverage within the Nouveau NVC0 driver and the associated work for bringing it up within Gallium3D / Mesa state tracker...

    Sad thing is the nvidia blob drivers don't give you that extension on Fermi cards!

    And it is a very important/interesting extension! I always thought the Fermi cards were unable to do that, but now it seems Nvidia just goes the AMD/Intel way: new features are only available when you buy a new product ....

      If You have preMaxwell card Nouveau is enough for daily use (of course if You not playing heavier games). For Maxwell and above is pain because those cards require signed firmware and Nvidia didn't release it.

        The nvc0 driver covers many GPU generations, but only exposes the functionality that is available on each generation. That functionality is only available on GM200 and newer GPUs (GTX 950+), and as such the extension will only be exposed on such boards.

            Except that if you have a card that Nouveau can't reclock and it has low boot clocks (read: Fermi), then you probably can't do any gaming. Apart from games that don't require anything from the graphics card of course.

                LOL at censorship. Still not a single benchmark posted in which Nouveau would come even close to the binary blob.

                  Ahh good to hear,

                  I was basing my information on https://nouveau.freedesktop.org/wiki/CodeNames/

                  And there the nvc0 would be 4xx and 5xx only, so it's just a bad nouveau driver naming.

                    The convention is to name drivers after the lowest-supported architecture. That's how all the GL drivers are named.
