Do you have a link ? I'm very curious (never heard of that one)...A new mode in Scavengers allows up to 9000 (!) players in one fps instance. Times are changing.
Yeah it has to be said UE always have been far ahead the Crytek Engine in terms of code quality (to be fair the bar set by CE was really low), performance, and even tooling. Whatever we may think of Epic Games and their insufferable CEO, they are a really strong developer team. What the latest UE can do is mind boggling, and yeah I will just mention The Mandalorian...As I said earlier, eventually all Big Dreams of cig will be default functions of UE or some such. And CIG will have contributed to none of it.
