I received the follow email concerning G200 drivers:
It is now 6 months since Matrox last released Windows 2000 drivers for the G200 card. The last release 5.03 had a fair few bugs. For this reason, I have put together a set of G200 drivers based on the 5.06 driver set. I have been running these drivers for 3 weeks, with no issues, and seen several bugs fixed in the OpenGL driver and better performance from the 2D driver when running at higher resolutions.Use the drivers at your own risk.
If Matrox are not happy with this unofficial driver release, then the answer is simple, RELEASE OFFICAL DRIVERS.
The driver can be downloaded from http://homepage.ntlworld.com/mark.gillespie/
It´s a 2.2Mb download, and is ONLY for G200, all other G series card files have been removed from the zip, to keep the size down (all other G series cards already have newer drivers anyway).
