Same speed on all machines and Tweening

BlitzMax Forums/BlitzMax Beginners Area/Same speed on all machines and Tweening

There is a reason why I use 200 or more updates per second. The nearer you get to the actual refresh rate of the monitor, the jerkier it looks! I've experimented with this and concluded that 200 or even 250 updates per second yields the best results. I'm not the only person around here that has reached this conclusion in past discussions.

The higher your game logic the more evenly spread the number of logic updates per screen updates you get, so the smoother things look over a number of different monitor refresh rates. And there's the problem for modern PC games ... the refresh rate of the monitor.

If you were to force a user to use a refresh rate of 60hz on their display so that your game would work with a logic update cycle of 60 updates per second, you would see jerks as some frames would see 1 update and others would then see 2 or 0! With a higher logic update speed you get more updates per frame, so although you still get a different number of them, the overall visual experience is a lot smoother.

You need to have a high rate to allow for the different display frequencies you can get. CRT monitors can run anywhere between 60 to 120hz (maybe higher). We nor your customers all have one of these new-fangled TFTs that only work at 60 or 75hz.

"Slower under powered" computers are not included in my target market, nor are they going to run anything created in BlitzMax.
