Intel, xrandr and performance.

My laptop has an Intel 945GM graphics chip. Right now I'm using Intel driver 
2.9.1. It works pretty well, but... 

If I turn on my secondary display with xrandr (it is an LCD screen connected 
via DVI, I'm setting it as a cloned display), graphics performs much slower. 
It concerns video and OpenGL (desktop effects inder KDE4). About a month 
ago, before I switched to KDE4, under KDE3 everything was working OK using 
the same hardware configuration.

Is it just a general case, or I have something not correctly configured?
