There are open source implementations of their launcher. Specifically there’s “legendary”, which is the thing that can download and launch games (this is a command line tool). Fortunately there’s also “Heroic”, which will use legendary in the background and give you a normal/usable user interface, desktop shortcuts and so on. Also doesn’t work like spyware for epic on your computer, as their own store/launcher does.
Probably “ports of call” on PC. Still haven’t found an actual modern version of it. There were some half assed attempts in recent years, all with such huge flaws that they still haven’t managed to be considered “playable”.
You can use legendary worth heroic as a user interface (both open source projects) to download and play games you own on epic, no need to install their software.
There is no need to use their launcher, as there are open source alternatives. “legendary” is a tool that can download sand install games from epic, but it’s command line only. Fortunately, there is also “heroic”, which is a GUI for it and honestly a pretty good one. Can also handle GOG games.
They work well for me, haven’t had epic’s launcher installed in a very long time.
A Ryzen 5 is a pretty large span of processors, ranging from “old and mostly obsolete” to “modern and highly capable for gaming”. Which one exactly would be helpful for others to help judge their own.
