R90 compatibility with Webcams for video conferencing

Has anyone had any luck with Webcams on R90's for teleconferencing? If so, which camera did you use and what software was being used? I am currently using 3 different types of cameras and I am getting the same results with all of them. They all take the CPU to 60-90% load with very choppy video.

Software: Cisco Jabber Video (which does not really allow for any quality configuration on the client side from what I've seen)

Logitech camera's:
C910 resolution: 1080
C920 resolution: 1080
C110 resolution: XVGA 1024 x 768
