I find the update to be super heavy, needlessly slow and kinda frustrating to use.
I will say it gets better after a few relogs, and when the game realises what it's doing with the gpu and cpu it seems to be fine??
I have higher performance, but it's running hotter than it was on black dragon and I really hope they optimise it a bit better.
I also have a bug where when i close out it takes it like 2 mins to fully close, which isn't ideal when before it closed immediately.
