But I have a different integrated chipset: ProSavageDDR. TwisterK has a lower memory bandwidth. It could be the 3D engine and the hardware scaler fighting for memory bandwidth.

AFAIK it doesn't make any difference on integrated graphics chips. They access both AGP memory and (shared) system memory with the full bandwidth. > [snip] | Felix Kühling <[EMAIL PROTECTED]> http://fxk.de.vu | | PGP Fingerprint: 6A3C 9566 5B30 DDED 73C3 B152 151C 5CC1 D888 E595 | ------------------------------------------------------- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!
