Everyone’s favorite OpenGL Software emulator has just released a v7.5 for development. Big feature in this release is the new “Gallium3D” infrastructure with support for Intel 915/945 and Cell. They’ve also added support for a few new OpenGL Extensions (framebuffer objects, vertex_arrays in bgra, etc) and improved a few quirks in the GLSL compiler.
Remember, it’s a development release so you won’t want to try this on anything too critical yet, but it’s a great preview of what’s to come.
