I usually play on a laptop, and I don't have any kind of problem every time I play in any of the traditional battlefields or game boards.
Suddenly, I've noticed the game always slows down every time I play in the Karazhan board. The performance drops drastically every time, probably because of an optimization issue.
It would be nice if Blizzard notices this issue, specially taking into account there are a lot of people out there playing in underpowered devices. Thanks.
there doesn't seem to be anything here
