The following new features are included in DirectX 6.1:
DirectMusic
- Several new DirectMusic components.
DirectDraw
- Enables AGP Command Buffers.
- ModeX fixed for AGP computers.
Direct3D
- Improved performance of DX5 RAMP rasterizer.
- Improved support for video memory vertex buffers.
- Improved support for PowerVR usage of Clear2.
- Drivers implementing ValidateDevice can now consider texture format
if required.
- Multitexture stage counting is now more accurate.
- Directional and Spot light types now operate correctly on Pentium II
computers.
- Ramp rasterizer now uses blue channel for gray-scale instead of
averaging. This is for compatibility with earlier releases.
- Vertex fog now works with SPECULARENABLE set to false.
- 16-Bit ramp rasterizer now supports COPY mode.
- New cap bit for textures which are not powers of two.
DirectPlay
- The serial service provider could attempt to send multiple blocks of
data simultaneously, which could cause the connection to be lost. Now
access is serialized.
- If a client was dropped from a session ungracefully and someone else
tried to join the game before the host timed out that player, all
subsequent joins would fail. Now joins succeed again once the host
completely times out all players.
