While the PC speed may affect the smoothness of the waterfall, I am rather dubious that it can impact the quality of the captured images. I would tend to point the finger on the video card used, or on the resolution settings. Spectran works best at 24 bits-per-pixel (16,777,216 colours or 'True Color' in Windows parlance) or at 16 bpp (that's 262,144 colours, or 'High Color'). Working at 8 bpp is 'tolerated', but the results are less than spectacular... 73 Alberto I2PHD
