Hi, the game is already doing this. As mentioned in the article, logic tick is running at a much lower frequency than rendering loop (30/60FPS). When playing in the browser and is minimized, the game will simply pause - rendering and logic. Browsers will throttle timers which will cause inaccurate logic tick as well. Most idle gamers actually do not like this behavior [1] - people prefer the game to run in the background as well.

The "background mode" mentioned in the article is about the Steam version, which runs in Electron and I have to set `backgroundThrottle: false` flag. In this case, Electron will not throttle timers and I can safely disable rendering while leave the logic running.
