I have my screen resolution in the game set at 1600x1200x32. What does the 32 mean? I could also set my resolution to 1600x1200x16. What would the difference be?
16 & 32 are the bit color that your monitor will use to display. I haven't found much difference in performance gain or loss so I use 32bit.
My desktop is set at 32bit so I guess it would make sense to stay with that.
