Microsoft.directx.direct3d Version 1.0.2902 -

Direct3D 1.0 was not loved. Developers complained it was "too COM-heavy," slower than Glide, and required writing an engine just to manage execute buffers. Microsoft heard this.

Version 1.0.2902 did not support hardware T&L (Transform and Lighting). Everything—vertex transformations from world to screen space—had to be done either by the CPU (retained mode) or by the driver using the CPU (never the GPU). True hardware T&L wouldn't arrive until Direct3D 7.0 (circa 1999). Microsoft.directx.direct3d Version 1.0.2902
