6.6.0.570163 - Performance Improvements Monday, April 4, 2022 Release Notes We are happy to announce a viewer that has performance tweaks. We focused on reducing image decoding time, less frame stalls, and initial font rendering time. As a result the viewer should feel more responsive. We can’t give specific timing improvements you will see due to the dynamic nature of content.
Please feel free to try it out and let us know of specific problems by filing a Jira.
We’ve made changes to vsync handling and added the ability to switch it OFF/ON in Preferences > Graphics > Advanced Settings.
