3dfx vs NVidia on FSAA

The Reverend has a very interesting email concerning the FSAA support that many people discovered in the recently leaked NVidia detonator drivers. According to 3dfx this is software emulated FSAA that wasnt even accepted by ZD as a valid AA technique for benchmarking. Basically just a hack, as opposed to the hardware style FSAA that the Voodoo5 boards can produce.

Any video card can support this type of emulated anti-aliasing through driver tricks that simply stretch the rendering resolution in one or both horizontal and/or vertical dimensions. [snip] ... was used in the past to fool benchmarking programs into thinking AA was supported. It was rejected by Ziff-Davis as a valid technique for doing AA [snip]. We define full-scene anti-aliasing (FSAA) to be an anti-aliasing solution that is (a) 100% compatible with all applications and APIs, and (b) performed in hardware. nVidia's approach is neither 100% compatible with all applications and APIs nor is it performed in hardware <snip>

  • Tech support in the future...

    FROM: Software user
    TO:  Husband 1.0 Technical Support

    Last year I upgraded from Boyfriend 5.0 to Husband 1.0 and noticed that
    the  new program began making unexpected changes to the accounting software;
    severely limiting access to wardrobe, flower and jewelry applications
    that operated flawlessly under Boyfriend 5.0.  No mention of this phenomenon
    was included in the product brochure.

    In addition, Husband 1.0 uninstalls many other valuable programs such as:
    DinnerDancing 7.5, CruiseShip 2.3, and OperaNight 6.1 and installs new,
    undesirable programs such as PokerNight 1.3, SaturdayFootball 5.0, Golf
    2.4 and ClutterEverywhere 4.5.   Conversation 8.0 no longer runs, and
    invariably crashes the system.

    Under no circumstances will it run DiaperChanging 14.1 or HouseCleaning
    2.6. I\'ve tried running Nagging 5.3, to fix Husband 1.0, but this all purpose
    utility is of limited effectiveness. Can you help, please!!!!














  • I know this isn\'t an innovation anymore but, I\'d like to see environmental bump-mapping, or another technology to produce the same effects, become more standard. It\'s not as high on my list as realistic looking poly-models, but it\'s a \"nice-to-have\", like FSAA.

    How about a \"gaming acceleration\" card. Create a PCI card that plugs into the machine and provides for specialized calculation of animations, interpolation of movement, physics (including liquids and gasses), AI state machines, etc. through a generic API provided for developers to use to implement these features into their games. You could be smart too, and give the API a backdoor where developers could use their own software implementations instead of the default ones provided with the API.

    There\'s still a ton of stuff that would need to get done by the main CPU, but this kind of thing would let people with older machines upgrade their whole PC less frequently, and give people with newer machines more headroom for the performance hits involved with the larger numbers of characters and interactive objects that will appear in massively multiplayer games.
