I only just bought PoE 2 days ago and I'm enjoying nerding out very much, but technically I'm finding it quite poor. The frame rate is really bad during combat, fluctuating wildly from 20 - 100fps. I'm also having lots of audio issues, from voice work skipping to choppy audio while just exploring (I've disabled my VPN and IP6 which helped but didn't fix it entirely).
So now I'm wondering is PoE2 on the same engine? If so will it be the absolute latest version of Unity which I know is a little better. Once I finish PoE I'd like to back PoE2 and buy it early, and the only thing that's holding me back is the worry of it running poorly, which is always my worry when a game uses Unity.
