Hi, i recently switched from a 64 Bit Vista with an NVidia 8800GT graphics adapter to a 64 Bit Windows 7 with an ATI 5770 graphics adapter. And i noticed that the PixelGetColor() function runs considerably slower on that new setup. I'm talking about a factor of at least 20 times slower on average. I have a script that makes intense use of PixelGetColor() and this script originally had a "roundtrip" time of about 20ms per loop. On the new setup the same script takes about 500ms per loop. wh
