Yeah so without having to overwrite some very deep OS settings, which will likely raise some red flags for your app requiring administrator privilege to run, you aren't going to get this. If someone has a browser thats taking up most resources, its gonna throttle everything.
There is generally very little reason to write anything but web apps these days for things that don't need to touch specific hardware. If you stick to as much native js/css/html as possible (i.e avoid large libraries), it will load blazingly fast and use way less resources then web apps that are considered fast.
