Reports around the web confirm version 11.0.2 of the Epic Games launcher has a lower CPU utilization rate and does not spike CPU temperatures when running idle.
On a related note, Epic Games is still giving away free games to promote its Store. Since the offer went live earlier this month, Epic Games has been giving away one free game per day. Some of these were well-known titles from earlier this decade, but most free games were lesser-known titles. Today it's Solitairica.
The hotfix is live now (11.0.2). It's not a full solution, but things should improve.— Sergiy Galyonkin (@galyonkin) December 29, 2020
