Twinview performance issues on GTS250
I'm using the latest drivers on Ubuntu 12.04 64 bit. I have a dual head setup with the left monitor at 1440x900 and the right at 1920x1080. In single monitor or Xinerama the performance is fine, but in twinview the entire system comes to a crawl. Basic programs eat up to 4 cores of my processor and if they are running even gedit goes slow.
