If i had to guess i’d say it is because of the electron framework. It basically bundles a modified chrome with the sandbox removed with JavaServer to run a web app on the desktop. Since chrome is bundled in amd a modified version, it cannot be updated. Therefore, since we didn’t update electron in years, in part because of breaking changes that makes this difficult, it uses an old version of chrome. Each update, browsers improve their Javascript engine and their APIs like WebGL, used by GDevelop for rendering. Your browser benefits from years of performance updates while GDevelop cannot.
