Why doesn't my GTX285 downclock when idle?

[Sojuuk]

I noticed the other day that my 55nm GTX260 downclocks to basically nothing when sitting at the desktop or doing anything not gpu intensive. My GTX285 doesn't do this. I have only ever seen it downclock once when I left it on over night but it immediately clocked up once I moved the mouse.

I have tried multiple drivers with no effect. Does the windows vista power options have any control on it?

If you're on Windows 7, try the newest driver. It fixed my down clocking problem.
