After passing the military base vybor , and enter the city. There was a huge drop in FPS, the game froze for more than 2 minutes. To be able to walk in the city of vybor and lopatino , I had to reduce the video setting to the lowest . I do not know the reason for the fall of the FPS, was not anything on my computer because I found the actions of the windows . I use windows 10 settings: i5 processor , 8GB RAM , AMD Radeon R7 M260 Video . The first update of expertimental not give this drop FPS .
