  1. Psolord

    I’d the prefer the automatic update to not be silent. I want to know when a new profile has arrived.

    That being said, Witcher 2 is also fixed, yay

  2. WacKEDmaN

    seems to be alot of background crap running with these, stupid automatic update crap mainly.. i dont have a need for it :/

    guess i have to do a clean install, remove nvidia update..and HD while im there..

  3. xcbb

    Some info about what the two new OpenGL extensions do would be nice:
    GL_NV_path_rendering
    WGL_NV_DX_interop2

  4. DrBalthar

    Check the OpenGL extension registry on OpenGL.org should be a description there

  5. xcbb

    The reason why I read news sites is that I don’t have to go to every site of some organization/someone/company/government to check what they have done recently

    A nice few lines of explaining their purpose=function would be appropriate for geeks3d.

  6. Michal

    AFAIK, NVIDIA has not released any papers describing new extensions.

  7. Meda

    Don’t use these, made the Witcher 2 run a lot slower. extremely slower. reverted back and it was fine. i5@4.3 ghz, gtx 460 SE, 8gb cosair dominator.

  8. DrBalthar

    Thanks Michael, I think that explains it xcbb. That’s a bit odd though I thought extensions normally are immediately published on the registry. How else are people able to try it out besides nVidia interns only?

  9. realbabilu

    Does it upgrade OpenGL performance like PBO Texture Performance and glReadPixels that lack in 4xx and 5xx?
    Please test OpenGL performance upgrade on Cinebench..

  10. DrBalthar

    @realbabilu In 2011 you shouldn’t use either of these functionalities (their old fashion and known to be slow)

  11. Ivan Paulos TomΓ©

    @DrBalthar

    Do you believe this B******T from Nvidia ? glReadPixels is not a deprecated function and it’s artificially capped from Nvidia in the driver to force a rupture in the market. they may fix this, but we have no confidence in them anymore. They will probably fix this and broke any other OpenGl thing to slowdown and throttle users.

    @realbabilu

    No it doesn’t upgrade perfeormance, the problem persists and Nvidia has no words to say about it, because it’s the way they want to see the market. This is made to cause prejudice to OSS and OpenGL users. Don’t buy those unless you’re only a media consumer. If you intend to start to jump to professional side, this is not the MId Range card that will helps you with the task.
