Fast then slow, using bitblt

9
Hi all,

Been a while since I have visited this site, I am now a dad and proud of it, anyway will get to the point. I have been coding a sprinting game using VB6 and bitblt, while testing things I noticed something which concerned me, so I will take it from the top.

When the computer is switched on after XP has loaded everything, I go in and run the game - everything runs smooth and goes to plan. Let's say I now go on the internet. After loading up a page or two I exit the net and go back to VB6 and my game. If I run the game now it runs noticeably slower.

Why is this?

And is there any way to rectify it?

Any help will be greatly received.


Happy coding.
