The lags are there but it’s playable on my i5-2400. I did take all gfx down to minimum to make sure it works. I am sure they will do what they can to improve on this.
There are some issues I’m having but it’s a nice game, imo definitely worth its money. I bought games for more that were worth less to me. That being said I am also hoping this is just the beginning. If it’s worth the money for you, only you can know. 🙂
