I find that the beta 3 driver works ok, when the system is booted and logged on. I use gfxCardStatus to ensure that there is no power based graphics switching going on.
However, where I see the issues are when I lock my screen (when leaving my desk) using fast user switching. When I return and try to logon, the console is hung. Spinning disc. No keyboard input possible. I have to hard boot the machine to get going again.
Never had this issue on SL, so have had to revert to SL as my three screens are crucial to my work.
So it seems like there is an issue with the driver irrespective of the power switching.
