Mark has just started a blog about Managed D3D for Devices (MD3DM). It early days for this technology since it relies on both Windows Mobile 5.0, which was recently launched and as yet there no no release devices using it, and .Net Compact Framework 2.0 which does not release until November. You can however get the beta of .Net CF 2.0 which includes all the emulators you need to get going. The frame rate won't be great but you can start experimenting. So you read Mark and get ready. We will cover this technology fully here on theZBuffer.com.
