Actually it may be the windows... If you have played with other version of windows like 7/8.1 then install it again and see if the game will work. Before one month i installed windows 10 and got 60 fps less... Thinking of going back to 8.1
I finally found the problem: from Control Panel opened Intel HD Graphics, there go to "3D" and switched both Anti-alias settings to "application" (maybe i did smthing else also). Now it works again. Anyway, got also nice FPS with that old Radeon 4850, so I continue to stick with that, even its power hungry
I fully understand that you were completely incapable of reading any of the above posts....

So, Try to read that, "I made a change in Win 10 and it worked again"
But, as you are a complete fwit clearly reading posts, or having any idea about IT, is completely beyond your comprehension.
