The day I received DBPro , I made a little demo to see the speed improvement on DBPro in comparison with DBV1 for 2D graphics.
That demo is very basic and only use "PASTE IMAGE".
No sprites command used .
I also use the EXCLUSE DISPLAY MODE to get smoother scrolling.
And with test , i get more than 380fps when i turn off sync ( sync rate 0 ) , on my 1.2Ghz+GF2TI64 PC.
It is strongly inspired from the game called "shadow of the beast" from Psygnosis on Amiga .
