standard practice.
Is it? Well I *might* add it to windowed mode. It's just that say your desktop Hz is 85 this only gives you 11.7ms to do stuff in to maintain a smooth display. Stick in a delay (1) and that's 10.7ms. On slower systems, where the logic and drawing takes a while, this 1ms could push it over the boundary into dropping frames. It's a bit sad to add in a delay after you totally optimise the rest of your code. But I'm just a pureist speed freak, that's all :-D
