Microsoft has updated its Edge browser, achieving a First Contentful Paint (FCP) of under 300 milliseconds by using its WebUI 2.0 architecture instead of the traditional React framework, resulting in a 40% average reduction in load times for thirteen core features. The updated settings UI shows a fourfold improvement in performance compared to the previous version. This release builds on enhancements from May 2024, which improved launch times by 42-76%, and an optimization effort in February 2025 that targeted fourteen interface subsystems. Internal tests confirm the settings panel now consistently renders in under 300 ms. Microsoft plans to extend these performance improvements to Print Preview and Extensions management throughout 2025.
