BeagleBone LCD Cape sampling rate

Hi I’m using the LCD4 TS and built an app with embedded QT. I’m having a problem with the TS driver pumping out too much data and overloading the CPU. I have high priority threads running in the background (Using angstrom, no RT patch) of my application, and as soon as I touch the TS my CPU usage shoots up 25% or more, and my high priority threads get starved.

Is there a way I can reduce the sampling rate or reduce the amount of data passed to my app from the driver? I’ve looked at ts.conf and don’t see anything there.
