I will download it when I have time. I did research and saw some other people posted the same problem at different years. It's the same for all, first 5-10 minutes you play with everything maxed out with no lag and very high performance, and then something triggers and the game starts lagging for no obvious reason. Another interesting thing is that when I minimize the game to tray for 5-10 sec and then open it again, it will play without any lag for 30-40 sec before it will start lagging.
