Just an FYI. As you know, the game requires a card with a vertex shader. It no longer requires a pixel shader as of the first patch because for cards without a pixel shader, some or all of the pixel shader effects are replaced with legacy TnL effects, some of which (e.g. shields) are from BCM Gold).
The GF4 MX cards do NOT have a vertex shader, but nVidia was [cheating] and emulating this in their older drivers. They have since removed this capability in the newer drivers.
So, if you have a GF4 MX card and want to get the game to work, go to the nVidia website and from the archived driver section, download this driver.
