discusses graphic card temperature spikes caused by
the Epic Games Launcher, even when the program is idle. The hot hardware experts
discuss the details of what's going on:
CPU temperature and usage spikes are not typical of game launchers. When
experimenting with the Steam and GOG launchers, CPU idle temps and usage
remained nominal and much lower, after an initial brief spike on loading. So
what exactly is happening with the Epic Games Launcher that idle temps are
spiking and CPU usage is unnecessarily engaged?
Doing some testing on another personal machine, we noticed that the Epic
Games Launcher has five different processes open at one time. Out of curiosity,
we opened up Glasswire, which is a free network traffic monitor. We could see
that the Epic Games Launcher and associated processes were firing off data at
regular intervals to over 22 different servers. This was happening whether we
had the launcher open, minimized, or in the background. The larger spikes shown
in the Glasswire graph below are from when we reopened the Epic Games launcher
after closing it.
Another interesting discovery is that the “EpicWebHelper” sent some data to the
Over the course of approximately an hour, Epic Games sent more data than 514KB
of data to some server(s) somewhere. This is more than 14x what Steam and NVIDIA
GeForce Experience sent in the background during the same timeframe. While it
remains to be seen if the data collection is the cause of the CPU usage issue,
something smells fishy here. In fact, it may be advisable to kill off the Epic
Games launcher for now, when you're not actively using it.
