Enthusiast Colin Kornaby decided discoverwhy in the main menu Warcraft III: Reforged such poor performance.
A short investigation led to the fact that the whole menu is a web application that runs on Google Chrome. Moreover, it works worse than the game itself. According to Kornaby, this is due to the load on one core of the processor.
The enthusiast also notes that during the gameplay Reforged loads its processor by 25%, while the main menu by … 150-160% (two processes, one at 100%, the other at 50-60%).
