key release latency on toshiba e740?


key release latency on toshiba e740?

Postby Guest » Feb 6, 2003 @ 4:10am

I've been playing with gapidraw on my toshiba e740. When I run the collisionmask sample program and move the sprite around with the keypad I've noticed quite a bit of latency from when I stop pressing a direction and when the sprite actually stops moving. From the on-screen values I'd say it moves 3-4 pixels after I release.
The program is pretty simple so I'm at a loss to explain it from software- but 132 msec lateny doesn't seem likely to be hardware either.
Is anyone familiar with this?

I've noticed the same thing with the little programs I've written. So far I've tried to compensate with things like only processing movement every other frame, stuff like that. It's not the greatest solution and definitely isn't for every game, but it helps sometimes. I'd be much happier if there was a better solution! :)

BTW, if I understand the suggestion in the previous post correctly, that's not the issue -- at least not in my programs. I'm targeting and hitting 30 fps, so that shouldn't allow messages to queue up, right? I'd expect that to happen if I were taking too long for each frame.
