Velocity9x

Windows 98 SE · Windows 98 · Windows 95

Hardware 3D for Windows 98 on period and not-so-period cards.

  • DirectDraw on the 2D engine and a Direct3D HAL on the 3D engine, including DirectX 8 on selected chips
  • An OpenGL 1.1 installable client driver, loaded by Windows’ own OPENGL32.DLL
  • Glide 2 and 3 for 3dfx games, and ATI 3DCIF for Rage games, on any card with a 3D engine
  • One package per chip family; installed copies update themselves with a signed updater

VelocityNT

Windows 2000 · Windows XP

A display driver for Windows 2000 and Windows XP.

  • Targets Windows 2000 SP4 x86 first, then Windows XP x86
  • Starts with the S3 Trio64, the card Velocity9x started on
  • Aims for a family-based driver with GDI, DirectDraw, Direct3D, OpenGL and Glide
  • No release yet: every feature is implemented and measured before it is advertised

From the test records

Things a Windows 98 driver isn't supposed to do

Each of these is a result recorded on one physical machine, at the version shown on its page.

  • Intel Gen3

    Pixel shader 1.1 on a netbook chip

    From 0.47.0 the GMA 950 runs DirectX 8 pixel shaders on its own engine. 3DMark 2001 SE completes with its pixel shader tests: 528 on an Atom N280 netbook.

  • Intel Gen7.5

    HD 4600: hardware T&L in OpenGL

    Transform and lighting on the card, two texture units, and the DirectX 8 interface. Half-Life runs at 174 fps in OpenGL, windowed, on Windows 98.

  • AMD GCN

    Command processors and microcode

    Evergreen, Cayman and GCN Radeons are fed through AMD’s own CP and SDMA microcode. Quake 3 runs on the HD 5770 at up to 1600x1200.

  • S3 Trio3D

    3DMark 99 on S3D silicon

    The S3D engine draws only what it can express exactly, refusing the rest. On real silicon 3DMark 99 completed at 335, Final Reality at 3.21.

  • Glide and 3DCIF

    Vendor APIs on other vendors’ cards

    Glide games race on an Intel GMA 950; ATI’s 3DCIF demos draw on a Rage XL PCI that ATI’s own 3DCIF never supported.

  • S3 Trio64

    Faster than the vendor driver

    Where it started: on a physical Trio64, Ironfield RTS ran at 27 fps against S3’s own Windows 98 driver’s 25, with GDI acceleration.

Your machine could be the next one on the list

Most cards in the database were brought up on someone else's hardware: a survey sent in, a test run reported, or a machine lent to the developer over the Internet through the V9x Remote Agent's remote help. If you have a card the drivers don't support yet, that is how it gets supported.
