Your brain can't interpret images at much more than 120fps and you're monitor can only output at about the same or less. At 72fps is looks like the gears are actually turning. At 650fps or 1600fps you're only seeing every 5th or 10th or 15th frame of what the computer is actually calculating and putting into video memory. BTW, you're lucky to get 8000fps off-screen. I get ~550fps at regular size, ~75fps at full-screen (1024x768x24) and only ~1550 at regular size off-screen. Probably due to lack of DRM-support of nvidias? or is that just wishful thinking ;-) Jason -- [EMAIL PROTECTED] mailing list
