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?
