I get 1,980 odd as the frames per second with that code, but I also get the bar of the refresh of my monitor showing too. I do see now though, how that code is a lot better. I especially like that strobe = 1 - strobe line. Without the Flip 0, and just Flip instead, I don't get the refresh showing on the screen, but the frames per second drops to about 85. I realise this is because of it having to wait, but it still seems to be accurate too. Thanks! =)
