I am in the process of creating a fairly cpu intensive patch that is controlled by a HP 2310ti touch screen. I have tried to optimize it as much as possible but the patch does not seem to react very well to the touch inputs.
The setup is a i7 with 8 gigs of ram and 2 ati graphics cards running separate projectors, so there should be plenty of ressources.
When I use a mouse it works without a problem. Do anybody have experience with how to optimize touch inputs in max msp or in windows 7 in general.
