    30 bit Picture output for PC

    In fact, that was a very simple loop 'without a loop' (portions of code repeated for each scanline) that changed the pallette registers 3 times per line. You could get 512/4096 colors that way (out of 16) without the flickering, but not more than 48 (that might be bit unprecise) in one line. But...

    dual (or more) channel memory in graphics?

    Simple - in voodoo '1' memory was split (physically) between texture memory and the framebuffer. Both parts had independent buses, so it was two- or even three-channel memory 'controller'. On voodoo2 you had 2 tmus, so it was 3-channel by default, and after setting up the SLI configuration -...

    dual (or more) channel memory in graphics?

    AFAIK, modern gpus use 'sort of' multichannel memory controllers, and about the old ones - have you ever heard the name voodo graphics, for example?

    Best card for Photoshop ?

    Creative has some cards based on P9 (or something like that), which do have apps using a GPU for 2D photo editing. I'm not sure if this includes the Photoshop though...

    Speed: assembly vs. HLSL shaders

    It just proves that hardcore asm coders are dying species. Probably people just go with straightforward routines, without thinking too much about the penalties or chip architecture. Or maybe compilers "optimize" the code too much, cut the precision or something, I'm not an expert, but results of...

    OpenGL in asian mobiles? Where's the MBX?

    Hehe... didn't check it deep enough. And how about the Motorola? http://www.motorola.com/mediacenter/news/detail/0,1958,3051_2494_23,00.html

    OpenGL in asian mobiles? Where's the MBX?

    Looks like STM got itself into some kind of korean mobile-OpenGL alliance. No sign of PowerVR... http://www.eet.com/sys/news/OEG20030722S0035

    PowerVR encrypted texture data?

    From the first diagram it looks like the data on memory bus is already encrypted, so probing wouldn't help that much. Im still under impression, that such measures aren't too friendly. I'd accept only using it against game cheaters, bechmark cheaters, etc. On the other hand, if someone would...

    PowerVR encrypted texture data?

    Hmm... on the other hand, maybe PowerVR wants people to use their chips for general cryptography? Creative is marketing versions of P10 with "photo-stitching accelerator" banner, so maybe this one would be crypto-accelerator, "perfect for all your secure needs"... ;) Simon: It simply looks...

    PowerVR encrypted texture data?

    Maybe: why US and Japan? Behind most of DRM lobbying and "initiatives" stands RIAA, and similar thing can be told about japanese Sony. The later is well known for "protecting" people form doing too much stuff with their hardware. How do you think, why after all these years of producing mini-disc...

    PowerVR encrypted texture data?

    OK, but why textures? I thought DRM would be more about the framebuffer. Is this just overkill or some sneaky, more general way of crypting graphics stuff? Also, I'd expect implementation of such DRM techniques from Japan/American companies rather than Brits.

    PowerVR encrypted texture data?

    Do you think? It's quite common to scoop parts of enemy weapons and reverse-engineer them, but in this case it's more about short-time tactical info. If you have access to a nav system of your enemy, you could find some very useful stuff, like what they know about you, how good their maps are...

    PowerVR encrypted texture data?

    Hmm... maybe it's for military or something. When the chopper crashes, for example, and is not completely destroyed, someone from the 'other side' could extract data from it's nav systems. Crypted textures used in maps would add another bit of security in such situations.

    Videoshader and colour blind people

    Since there are different "versions" of colour blindness (these people don't see R, G, B, RG, RB or GB colours), best solution for them could be to use only grayscale modes. This way they'll see at least correct brightness levels. Other thing is, that such images will look somewhat different to...
