    Phoronix: Intel Goes Ahead & Drops i915 Driver From OpenGL 2.1 To 1.4 By Default

    Intel Linux developers have partially reverted Mesa work done years ago to drop the default OpenGL behavior with the older i915 driver from exposing OpenGL 2.0+ support to now only having OpenGL 1.4 out-of-the-box...

      Here is a list of some chipset names:
      https://cgit.freedesktop.org/mesa/me...i915_pci_ids.h

      Notably this does not affect any of the i965 class GPUs.

        In other words, unless you have a *really* old core2 system or a pineview netbook, this doesn't affect you.

          So this is about the third generation graphics then?

            At least it had "GL2" for near 4 years

                I noticed there are some Atom chipset among the third generation graphics that supports 1.5 on Windows. Will these be affected?

                  That's surprising. OpenGL 1.5 requires occlusion query support, which the hardware does not do. opengl.gpuinfo.org only shows a couple of OpenGL 1.5 implementations - XGI, a couple GeForce4s, and...surprisingly...a 965 (which should absolutely do GL 2.1). Can you point us at more details?

                    And that's not only a Chrome matter.

                    In GNOME, Totem's performance was miserable because of this.

                    I notized the change between versions 4 years ago.
