Surprise it’s speed wars between Electron apps. Steam is based on Chromium/Electron.

The new version of Epic is based on Tauri. Also written in JS and probably React (haven't decompiled it yet) but the web runtime is part of Windows instead of shipped with the app so it takes less disk space and RAM. And you can write perf sensitive code in Rust for even more speedup.

		I also avoid installing Tauri apps too. Anything that loads Javascript that’s not my browser is a bad smell and potential resource hog IMO.

Interesting, I didn't know they moved to a Chromium based desktop application. But honestly, I don't feel like there's any performance issues with the steam desktop client (I'm running it on Fedora, but I'm assuming performance is relatively similar on different platforms).

		The switch from IE/Trident to Chromium happened in 2010 alongside launching support for Macs.
