Heroes 7 lags in the main menu.

Only the pirated version has performance issues; the slowdowns are caused by the game constantly trying to connect to Ubisoft, so you need to block incoming and outgoing connections in your firewall. If you can't do that, disconnect from the internet and enjoy the game.

As for me, I bought the licensed version on Steam for 509 rubles and I'm having a great time; no lag, no bugs... version 2.22, I think.
