lag when using screen for games

[mikeeey]

now since I am new to using a pocket pc (rather than a SP), im not sure if this happens with all devices, or just the Kaiser. When i play games and emulators that use the touchscreen, the framerate slows down quite a bit as soon as i touch the screen.

so does this happen with other devices?

searching up the forum a little more i found out it happens with all QVGA htc devices. well that sure sucks, i wonder why they dont fix it. 1 thing I'd like to know is how game companies that test their games on pocket pc's dont notice the lag when using the touchscreen?
