My card is a G400. I wonder why they are so different. Does the G550 support fast-writes? G400 doesn't so that may account for something. Blit 3.00 secs ( 281.52 MPixel/sec) Blit colorkeyed 3.00 secs ( 281.62 MPixel/sec) Blit with format conversion 3.03 secs ( 108.11 MPixel/sec) Blit from 32bit (alphachannel blend) 3.04 secs ( 107.68 MPixel/sec) Stretch Blit 3.09 secs ( 130.46 MPixel/sec) Stretch Blit colorkeyed 3.09 secs ( 130.50 MPixel/sec) What's next? Maybe make df_dok draw into an AGP surface so we'd see how much the other benchmarks suffer. Probably have to turn off the SGRAM stuff with this. -- Ville Syrjälä email@example.com http://www.sci.fi/~syrjala/ -- Info: To unsubscribe send a mail to firstname.lastname@example.org with "unsubscribe directfb-dev" as subject.
