** Description changed:

  Binary package hint: compiz
  
  glxgears shows the following fps on my Nvidia 8600GT card when compiz is
  running:
  
  173.14.12 driver:
  
  Hardy, 32 bit: 4900 fps
  Hardy, 64 bit: 5000 fps
  
  Intrepid, 32 bit: 4200 fps
  
  
  177.80 driver:
  
  Intrepid, 32 bit: 3000 fps
  
  ie there is a massive 40% in performance between Hardy using the old and
  Intrepid using the new driver and a 15% drop if both use the old driver.
  
  With compiz disabled, all combinations of O/S and driver show around
  5800 fps.
  
  So with the new 177.80 driver, compiz is reducing glxgear performance by
  close to 50%.
