Systems and methods described herein provide for rendering and quality monitoring of rendering of a 360-degree video, where the video has a plurality of representations with different levels of quality in different regions. In an exemplary method, a client device tracks a position of a viewport with respect to the 360-degree video and renders to the viewport a selected set of the representations. The client adaptively adds and removes representations from the selected set based on the viewport position. The client also measures and reports a viewport switching latency. In some embodiments, the latency for a viewport switch is a comparable-quality viewport switch latency that represents the time it takes after a viewport switch to return to a quality comparable to the pre-switch viewport quality.
