QT and RVIZ
There seems to be a big difference in performance between running rviz standalone and running rviz inside of QT. Any thoughts as to what is causing this drop in performance? My guess is the standalone version is using the GPU since the processors do not seem to get bogged down as much.
Which graphics hardware and drivers are you using? Which version of ROS?
ROS Hydro, Ubuntu 12.04, GeForce GTX 760, NVIDIA Driver 331.62
