Does a computer's graphics work better if its set on 16-bit instead or 32-bit?
 
If you want better performance, go for 16-bit. If you want better looking graphics, go for 32-bit.
 
The only time you'll really see a difference in 16 bit is when you're looking at a texture with a color gradient (i.e. one edge of a wall is brightly lit, while the other end is not). Instead of smoothly transitioning from light to dark, you'll see the transition in "bands" of color, ranging from light to dark. This is because 16-bit color displays far fewer colors than 32-bit, while 32-bit color needs more decimal-point precision (floating-point precision?), which is why it requires more resources.
 
On modern graphic cards it should make nearly no difference in performance if you choose 16 or 32 bit, so go for 32 :)
 
are there actually any moderators on this site anymore?
 
On never machines there are little or no difference in using 16 or 32 bit.
