highlandcattle> Tematic/Castle wrote a driver that makes the card work but also does rectangle copying and solid filling in hardware (you'd find the machine unusably slow otherwise)
Simon ported the 3D driver and OpenGL-compatible library. There are presently no 3D programs for the IYONIX pc/RISC OS capable of using this
Geminus uses the 2D hardware acceleration more extensively with the aim of making the desktop more responsive and doing so without requiring applications to be modified.
Geminus does still require the Tematic/Castle driver for setting up the screen and defining/moving the mouse pointer but does everything else itself.
