More than that, I seriously doubt an RT kernel is going to help with this type of situation. RT kernels are meant to help with real time situations, and camera applications do not to my knowledge do not need, or even want real time operation. In fact, I do believe if you do the research a real time kernel can potentially slow down disk access, disk caching, and the like.
