I am running the latest nvidia beta drivers 301.24 but then also I am facing this weird problem with the game. I found that when I run or walk then the textures started flickering. This shows me the black color. I am not able to understand that what the reason for this problem is. There is no problem with other games. When I play other games then they runs without any problem. Now I am with the hope that they will release some patch for this problem. I can see that there are also some of the other users who are posting with the same problems on various sites. So I am happy that this is not just me with this. I liked the game but if they will continue in the same way then I might have to stop playing the game.
