I'm not aware of any loss, I think with it off the feature is created in software, where as it would be done with the graphics hardware with it on. > turned alpha blend back on and changed color depth to 32 bit, > retstarted AD and that also worked but moving the component > was so slow as to be useless > > card is G450 2 head This is a very old card, my G550 was slow too, with the high colour depth, so I'm back at 16bit with alpha blending off. 16 to 32 bit doubles the amount of data the card has to move around to move an image on the screen. At the same time leaves less RAM on the card for other features like Alpha Blending. I'm about to get a Matrox Parhelia APVe PH-E128APV in a new computer, this card has 128MB of RAM. I'm running two lcds 1920 x 1200. > BTW, the G450 allows 16/24/32 bit depth on screen 1 but only > 16/32 on screen 2, or maybe that has to do with the monitor > types ?, > 1 CRT, 1 LCD, both 21's It's the card limitation AFAIK. > another note > the program sure is poky and jerky while moving the component and my > first practice board only has 4 components! > it feels like some huge grid, but the snap grid is at 25mils Component snap grid ?
