    Hmm so far the best driver version was 263.06.

    Latest 266.35 beta was totally broken and freezed my pc very often.

    I’m not sure to upgrade this time 🙂

    Nevermind… I just tested the new drivers.. they seem great so far…

    In unigine (tropics demo) I get more speed than with 263.06 drivers.

    Score improved from 2972 to 3047!

    I also tested the drivers in bfbc2 and there were no lock-ups.

    Well done.

    Oh.. by the way… the finally put a profile for 3DMark 11.

    No need to create it.

    @msweed4life: thanks for this report, even if it has no relation with NV drivers, it’s important for me! Indeed I’m testing latest AMD drivers and they have changed something because the tessellation doesn’t work anymore!!!!!

    im noticing that GPU Caps Viewer 1.9.5’s HW Geometry Instancing and Soft Shadows demos are crashing with these R266.58s..

    4D Quaternion Julia works fine tho!

  6. WacKEDmaN

    add HDR, DoF and RadialBlur demo to that crash list aswell!

    the log is no help :/

    OpenGL 2 tests still crashing on R266.58 with 1.9.5

    works with 1.9.4

    Important note:

    I did some benchmarking and I found this:

    Compared to 263.06, 266.58 drivers are INDEED faster.

    For example in UNIGINE Tropics I usually got 2975 points with my cards set at 820/2020.

    Now, with 266.58 I get 2975 with the cards set at 800/2000 and 3047-3050 points if I set them at 820/2020!

    That’s a great improvement!
    I wonder how fast they can push them and if there are hidden settings in driver to manually tweak this 🙂

    also JeGX, is the performance of other opengl apps supposed to take a performance hit by just having caps viewer open?

    About GPU Caps Viewer… I have no crashes with 1.9.3.

    And this profile I use for SLI:

    Profile “GpuCapsViewer”
    ShowOn GeForce
    ProfileType Application
    Executable “GpuCapsViewer.exe”
    Executable “Gpu.exe”
    Setting ID_0x00a06946 = 0x084000f5
    Setting ID_0x1033cec1 = 0x00000003
    Setting ID_0x1033cec2 = 0x00000002
    Setting ID_0x1033dcd2 = 0x00000004
    Setting ID_0x1033dcd3 = 0x00000004
    Setting ID_0x1095def8 = 0x02c00005
    Setting ID_0x209746c1 = 0x04280001
