This page will serve as a centralized location for documentation of Hybrid-Windump's functionality and potential uses in Bumblebee. Simply put, Windump renders windows on the Nvidia card before dumping them onto the Intel-rendered desktop. This is advantageous over the VirtualGL method because hardware interfaces such as NV17 Xv and VDPAU are exposed, Furthermore, there are performance gains to be had when compared to VirtualGL which renders everything twice.
