Hello everyone i watched all these videos of people running games like Phantom pain and arkham origins on game native no problem ,but i cant get past a black screen on Phantom pain running it from.custom games folder.

On the other hand i finished ground zeroes from.a custom games folder however
i noticed Ground zeroes gets stuck on Checking Save Data screen infinitely and cant load and the fps drops to 5 and stays there .

I tried over 20 configs on both Phantom pain and ground zeroes but cant get them to work properly especially phantom pain since it only gives a black screen.

Did anyone manage to run these games from a custom games folder ?and if yes please share your knowledge .
