On Macs, millions of colors requires the resolution size multiplied out times 4 bytes. For example, at 640 X 480, millions of colors requires 640 X 480 = 307,200 X 4 = 1,228, 800 which is more than one megabyte. In theory, millions of colors should only require 3/4 that much VRAM, (24 bit color = 3 bytes, so multiply by 3 instead of 4) but for various reasons, using three bytes per pixel kills performance compared to using four bytes per pixel. Refresh rate shouldn't enter into the VRAM requirement. I.e., the VRAM requirement should be the same for a given resolution and color depth regardless of whether it is set to display at 67 Hz, 75 Hz, 85 Hz or 100 Hz.
