Default HIGH Screen resolution kills performance in WIN/XP?

I got my resolution AS high as possible right now.
I read/heard the higher the resolution, you get a drop in performance?
1280 X 1024 right now, what's a good one for performance?

Or does it matter????????


I see there are (as of yet) no programmers in this thread!
[ assume byte == 8 bits ]

Think about what the poor ol' CPU has to do (assuming your video card/MB has
no extra performance features).

640x480x4(bytes (32bits)) == 307200 x4 == 1228800.
..... and it has to do that 60 times a second to be flicker free:
times 60Hz == 73728000 bytes per second.

1280x1024 == 1310720x4 == 5242880
times 60Hz == 314572800 bytes per second.

How could it not affect preformance?

Now, the hardware guys in this NG know that newer video cards/MBs have some
special features that speed things up. That's why thay say, "it depends".

That help any?
