As of writing this, the current build is v1.2.1.6 but the issues I’ve been having are much older. I’m currently playing on an Xbox One S, and while yes it’s a last gen console, this is by no means a next gen game. I can’t speak about the Series X/S experience.
I want to start by saying I love this game. With that said, playing this on my Xbox is a miserable experience at times and it’s due to the performance. The game stutters and loses frames frequently - especially when a lot is happening on ultimate - but even on normal. Not just losing some frames but grinding to an absolute halt. It’s also prone to crashing. I can do maybe 4 runs of 2 shards in SR before the game decides to quit running and it’s a frustrating experience.
Multiplayer is worse when you factor in latency. Far worse. I convinced my friend to get the game early on before I was aware of how poorly it could run, and he was put off by these problems. Both of us at about the same time said it was like watching a stop motion video or a powerpoint because it was so choppy.
Please address this in a future update and optimize the game better, it’s a shame to have such an amazing game’s experience ruined by this port.
