  1. glBindBufferARB and following calls fail silently on NVIDIA

    I'm debugging an application (old code, which is why it's using glBindBufferARB) which occasionally fails on NVIDIA hardware but runs well on AMD. Most of the code uses glBegin/glEnd rendering but...

    Re: Cg - nice, but makes me dislike NVIDIA

    Well, in fact, I'm already using DirectGraphics (which in some respects is a refreshing change after using OpenGL), and as I understand it, Cg will be part of DX9. I certainly don't claim that what...

    Cg - nice, but makes me dislike NVIDIA

    3Dlabs has been working for quite a while on OpenGL 2.0, one of whose parts is exactly this kind of compiler. Now NVIDIA brings out its own implementation to take all the publicity before 3Dlabs gets...

    Re: Why abolish display lists on OGL2?

    If the main use for display lists is state changes, then a simpler mechanism for that effect could be created.

    OTOH, I do like the idea of vertex arrays with state changes -- some form of...

    Re: Please help before I burn my machine.

    Hmmm... Don't know what to say.

    The TNT2 M64 should support 32 bit, although I'm not sure what this has to do with anything. Can't the software work in 16 bit mode?

    I think that you should try...

    Re: Rage IIc agp

    A new graphics card should do the trick. http://www.opengl.org/discussion_boards/ubb/smile.gif

    There's no OpenGL driver for the chip, and a new card will be much much faster and provide much...

    Re: sis 530, agp accelerator

    As Nobody pointed out, it's the drivers from SiS that need to support OpenGL. SiS no longer supports the 530 with new drivers, so if current drivers don't support OpenGL, you're out of luck, I'm...
  9. Re: glTexImage3d capabilities on different cards?

    I think that the advanced coding forum would be a better place to ask. Sadly, I don't have a card that supports this, so can't check. GeForce3 and all Radeons (including the new FireGLs from ATI)...

    Stencil buffer has been the same since the TNT days, AFAIK.

    Markk, these drivers are for the Rage Pro, not the Rage II.
  12. Re: stencil buffers, S3TC compression? How do these affect performance in 3D games?

    Here's some more info and clarification for you:

    The stencil buffer on NVIDIA hardware is only available in 32 bit Z mode. Since it it used for additional effects, it's not really a matter of...

    Correction: NVIDIA just released stereo glasses drivers for all cards and OSs. Yeah! Finally my Revelators will work on Win2K!

    Re: Stereoscopic view...

    First of all, if the glasses work with games, then I think that any full screen app will work with them automatically (more or less).

    Secondly, if you modify your card such that the GeForce2 is...

    First of all, I suggest that you post this in one of the programming forums, not in the software and gaming forum.

    Secondly, I suggest that you contact 3Dlabs. They are supposed to have pretty...
  16. Re: Does anyone know where i can get the OpenGL drivers for a ATI Rage/RageII pci card

    Pleading won't do you much good. The Rage II doesn't have OpenGL drivers. Even if it had, the game would probably have ran very badly on it, because it's a very old (meaning slow and bad image...

    Re: Lightwave 7.0 problem.. HELP!!

    Sorry about that. As I say, I don't know Lightwave, and probably nobody else here does.

    Still, let's try it some other way -- do you have any other OpenGL accelerated program that does work? That...

    There may only be one RC, but it can be reused by different windows.

    Everything should just work (doesn't mean it will, but it should). OpenGL is built into Windows (except the original 95).

    Re: Lightwave 7.0 problem.. HELP!!

    I don't know lightwave, so I have no idea if it takes advantage of 3D acceleration by default. Perhaps you could look for acceleration options. Sounds to me like you don't get acceleration.
