The game have been running bad lately.
Small stuttering and random small freezes. I have tryed all possible setting and nothing helps.
I believe its not my PC, since I have never had any problems normally in diablo 3, and I play games which require much more than this game, those i play on all maxed out.
It have happened before in diablo 3 some years back.
It usual happens when the game haven´t been updated / optimized a long time like now. I don´t know what it is, if its some system cleaning up or what it is that is needed.
Back then i think a patch did solve the problem.
In the current state I don´t want to play the season since its really annoying. Its worse in the start of entering a rift or new area. After a while its almost gone again. Until next zone or rift startet. I can´t explain it more than this.
I have been noticing a problem too. Stuttering and lag is becoming quite frequent. Also whenever I am using the mystic to transmog an item I get crashes if I spin my character around. never used to happen before but the last couple of weeks its quite frequent.
I thought maybe it was just my laptop but like you I play much more intensive games, like Skyrim, on max settings and dont have any problems so I really dont think its my system struggling.
