nvidia 9600 lag in X with xcompmgr in arch64

I recently upgraded from 7900GS to a 9600GT. I installed the 64bit beta drivers 173.08 (the only ones as far as I can tell that support 9600GT). Now when I try to using my openbox setup with xcompmgr, draging or resizing windows causes X cpu usage to go up to 100% and it is very laggy. I don't know if it is just the beta drivers or something else. This is my xorg.conf:

edit: Another thing I have noticed is that  apps will lock up for a few seconds (stop redrawing and taking input) every so often. It gets pretty frustrating. I didn't have this problem before I upgraded my graphics card.

I would suggest toggling the EnablePageFlip, BackingStore and RenderAccel options.

Also, see thread - try e.g.:

nvidia-settings -a InitialPixmapPlacement=0 -a GlyphCache=1

InitialPixmapPlacement of 2 can make 3D graphics pause occasionally on an nvidia 8800 - bizarre
