    Phoronix: NVIDIA Delivers Beta OpenGL 3.0 Linux Driver

    The OpenGL 3.0 and GLSL 1.30 specification were released back in August during SIGGRAPH 2008. Just days later NVIDIA had delivered a beta driver for Windows that added OpenGL 3.0 functionality, but Linux, FreeBSD, and Solaris users were left in the dark. Two months later though NVIDIA has now published a beta Linux driver that implements most of the latest GL/GLSL specification.

    Wow, first response!
    Quite a fast response from nVidia (for Linux that is).
    Does this mean that opengl2.1 will be a little faster with the new exposure of ARB_vertex_array_object, ARB_framebuffer_object, and ARB_half_float_vertex extensions?

    EDIT: It seems this still has the old 2D regression (the one affecting lines and circles in gtkperf)

      The OpenGL 3 tree branched off of the 177 tree at build 61, as indicated by the 177.61.xx version numbers, so it contains some, but not all of the features and fixes added in the 177.80 drivers.

          Yes I did have a suspicion it would be that way.

            Nice move by nvidia supporting OpenGL 3 so fast. And mid November we will have OpenGL 3 support in the closed-source ATI fglrx driver. 2010 that is.

              no -.- ati Support some OpenGL 3 parts since the Catalyst 8.9/8.10 ( 8.10 definitely because i dont have use 8.9 ). so AMD/ATI was faster.


              EDIT: ATI Support some OGL3 Extensions since 8.9 look http://www2.ati.com/relnotes/catalys...ase_notes.html

              New Features

              Catalyst™ 8.9 introduces the following new features:

              • Catalyst™ Control Center: New Display mode support

              • OverDrive™ support for QUAD CrossFireX configurations

              OpenGL™ 3.0 extension support

                From my reading of the ATI driver release notes, apparently only the Windows driver has the OpenGL 3.0 extensions. The Linux driver release notes make no mention of them.

                    So you're saying the Linux one has partial GL 3 support?

                      That ATI driver doesn't appear to have any OpenGL 3.0 support as it is missing the extension required to create an OpenGL 3.0 context, GLX_ARB_create_context. Of course, I wouldn't expect it to be there as the specification was only completed on October 22, the day before NVIDIA released their OpenGL 3.0 driver.

                        I knew the Windows driver had gotten partial OpenGL 3 support. But I thought that didn't apply to the Linux driver as well.

                          strange, 177.61.02 does not want to install as it detects that i have a Xen kernel, but 177.80 says i do not have one and installs

                              Awesome, now provide a driver that can be installed on any kernel and won't break with a switch between kernels, a true Linux kernel module that's actually modular, so normal users who don't understand the risk of installing the binary from Nvidia who then do a system update only to find their system totally hosed after it installed a newer kernel for them won't get fXXXed. Maybe the kernel module API needs some stabilization for that to happen, but regardless something needs to happen because it's a problem for many users.
