Ok I looked at the other test but the results weren't what I was getting in my test so I made this example with sprites (made using createimage so no need to download). It's a simple dot but making it larger, multicoloured or framed doesn't seem to change the results. basically the number is the number of milliseconds it takes to move and draw all the sprites to the screen. Native (1) is way faster at lower resolutions but even at higher resolutions can handel way more sprites without slowing than any of the other modes. OGL is fast and less affected by screen size but put to many sprites on screen and it's starts to crunch. 3 DX is slower than all of them but as it's the only one that Vsyncs properly it's way smoother. Anyway try t out the results will shock you. See next post for example
