FYI post. CE multiplayer still runs prefect (@1920x1080*) on my new 2021 system with the following specs:
Intel(R) Core(TM) i9-10850K CPU @ 3.60GHz; ASUS motherboard; Aus Geforce RTX 2060 - driver 456.71; Windows 10
I checked CE versions v1.42 & v1.43.
(*I had to apply the forced resolution issue fix as detailed in my 2016 post below.)
Please let me know via the comments below how its running on other systems, especially AMD based CPU and Video based systems.
