I also have the same low FPS and bad performances problems on a new PC I build. 20-40 FPS and the game is not even on max settings.I have a Ryzen 2700X with a RTX Rog Strix Advanced 2060, 16 bg memory and the game is installed on a M2 hard drive....And I have just purchased the Path of Fire before testing the game...and kind of regret it as I simply put can't play the game.On this system I can run most games on at least high if not ultra but on GW2 I have no chance. I have tried some tips posted on forum with no luck. Waiting for some fix before I can start playing again.
