HDTV Processor

Oh boy, another video processor! Seriously, I consider any type of video addition to a video card to be worthwhile. One of my favorite video cards was my Matrox Marvel G200 TV simply because it came with so many cool items. Besides offering high quality DVD and HDTV playback, as well as digital recording, the GeForce 256's HDTV processor offers plenty of other features, specifically:
  • High precision HDTV video overlay
    • 5 horizontal, 3 vertical taps
    • 8:1 up/down scaling
    • Independent hue, saturation and brightness controls through hardware
  • High bandwidth HDTV class video I/O
    • 16-bit video port
    • Full host port
    • Dedicated DMA video
  • Powerful HDTV motion compensation
    • Full frame rate DVD to 1080i resolution
    • Full precision subpixel accuracy to 1/16 pixel
Unfortunately, NVIDIA was rather quiet about the HDTV processor, and therefore I cannot provide anymore information on it at this time. However, as new information becomes readily available, be sure to read Tweak3D for the latest official news.

Who Will Suppport GeForce 256

Almost every bit of information that I have regarding GeForce 256 is interesting. But will everyone support it? Yes! Besides being fully compatible with DirectX7 and OpenGL specifications, NVIDIA is working hard to make sure developers know how to utilize these functions. Developers want a chip that has the power to make their games look better. If you were a developer, wouldn't you want your games to look better?

The Whole Experience

I predict that transform and lighting will become nearly a requirement in 3D games in the future. The reason being that once you've seen a game using transform and lighting, you won't want a game without it. Already on the list of games to support the GeForce 256 are Quake III, The Whole Experience, Shadow Man, Midnight GT, Halo, and Messiah. I'm sure there are plenty of others, because as of the time I'm writing this, the GeForce 256 hasn't even been announced!

Last Minute Additions

In addition to the massive feature list this chip boasts, don't forget to add in all five formats of DirectX6 texture compression. How about bump mapping? NVIDIA's GeForce 256 supports single-pass emboss and dot-product bump mapping. Thanks to the addition of T&L geometry engines, you can have realistic bump effects without sacrificing performance.
