I have disable the directx 11 in the options of the game and it works at 40 - 45 fps constant, i have try clean install of nvidia drivers to see if it can work the directx 11 but no luck.
This problem is of the Directx 11 because in directx 9 it works perfect.
Just wanted to know and try solutions for directx 11 because the game works more fluid and at better fps o 55 constant, if not solution then no problem.
