I was playing the game today and I had 2 freeze moments during gameplay.
One of these moments my screen was freeze for more than 3 seconds! I thought the game was going to crash but it continued running.
It was a long time since I face such problems or something alike. I think one of the last hot fixes is causing this!
Maybe NWI should provide some kind of benchmark tool that could help them to get data and improve the game performance.
