Fifa 15 lagging and running slow

[bilal619]

Hello, i am using sandboxie to run fifa 15 on windows 8.1, everything runs normal after the error message but the game has slowed down and there is a lag in the graphics, i have catalyst control center and have set fifa15.exe to high performance but it does not seem to work, i think there needs to be a way to set high performance for fifa from the sandboxie. any help would be appreciated.




P.S my pc has all the required specs

What is the point o running games inside sandboxie? Why don't you just backup your game saves?
