As Engageli continues to enhance platform features, it also aims to support a wide range of customer system environments, from lower-performance PCs to high-end machines. To balance these needs, Engageli offers unique bandwidth modes. In response to feedback about low bandwidth mode in previous versions, several improvements have been made in the latest release, 3.1.51-0927c.
Improvement 1: Reduced CPU and memory usage for better performance.
Improvement 2: Learner video remains on even in low bandwidth mode.
Improvement 3: Auto-switching to low bandwidth mode can be enabled or disabled for all sessions via class or site-wide settings. Users can manually select low bandwidth mode from the More Actions (three dots) menu if needed.
Here is a table outlining the differences between Low Bandwidth, Medium Bandwidth, High Bandwidth, along with the corresponding user experience for instructors and learners for Engageli version 3.1.51-0927c.
