    Phoronix: VC4 Gallium3D Gets Much Faster Texture Upload/Download Performance, Helping GLAMOR

    It's been a while since last having major progress to report on the Broadcom VideoCore 4 (VC4) open-source driver stack most notably used by the Raspberry Pi boards or the next-generation Broadcom VideoCore "V3D" driver stack. The lack of recent progress has been due to lead developer Eric Anholt being away on paternity leave, but he is back now with another update on this open-source ARM graphics undertaking...

      Does this fix the bug where enabling the 3D driver worsens 2D performance?

          But are you going to compile mesa, xorg etc to get that? New raspbian is probably over a year away.

              I don't think GPU is enabled by default in Raspbian. In spite of all the hype surrounding 3D, for most use cases 2D rendering speed is more important. Unless you are running games.
