I'm running Arch Linux.  The driver is an ordinary package, but it could be beta from nvidia's perspective I guess.  The latest that Arch has now is 313.30.  The card is
NVIDIA Corporation GT218 [GeForce 210]

Oh you're right, dragging windows (glxgears) does take the CPU usage of one core up to near 100%.  And I'm not even running a compositing WM (OpenBox.)
