Here's the live stream from 17 Dec, 2019 for those who asked for it on Discord

I wonder if it's actually a good indication on their confidence for 250 vs 250 battles?

Is it more than only a technical demo of UE4?

It's interesting to see how far they've come since then, maybe PI testers can share anything?

A couple things of note;

We randomize latency by hosting batches of 200 of these simulated players on separate servers from different aws hubs that then connect into the game server.

Movement updates are the most intensive aspect of network traffic for most multiplayer games (aside from heavy projectile/hitscan based shooters) but most mmos, the majority of the legwork on the network traffic is updating movement and position to all net relevant clients in the area.

We’ve made some significant progress and will continue to test this progress and make even more as we enter widespread testing phases. The road ahead will be perilous and bumpy. But will yield good progress for Ashes :)
