Check the app.log to make sure the game is using the correct video card.
You may need to force the game to run on the NVidia GPU.
Q:I'm experiencing black screens, tearing and stuttering.
A:Bootleg is not compatible with Intel graphics cards. If you are using a laptop with a Radeon/NVidia card, you may also have an Intel card.
The game uses the default video card which may be the Intel card.
Check in the app.log to identify which card FF7 is using.
To force FF7 to run on the Radeon/NVidia card, go into the graphics settings and "add" the file/app, "FF7.exe," to run on the improved performance processor.
