Resolution problem!!!

[rad111]

In mugen.cfg,
I set - Width  =1024
          Height =768

;Set this parameter to use a resolution-doubling filter. You will
;need a fast machine to use these filters. You will need to increase
;the screen resolution to at least 640x480 for these modes.
;0 - off
;1 - diagonal edge detection
;2 - bilinear filtering
;3 - horizontal scanlines
DoubleRes =2


However,I discover Width=640 and height=480 is better than Width=1024 and Width=768......

Why?

If I want getting high resolution of game everything.How to I do?

The width & height are at it's best if it is a multiple from the increments 320 x 240 (640 x 480; 960 x 720; 1280 x 960)

And besides, logic has to be placed here. If you double the size of a sprite, will it look as good? Nope.
