I'm trying to play the game but I can't. When I choose the character and start the game it appear "Error, out of video memory trying to allocate a rendering resource, Make sure your video card has the minimum required memory, try lowering the resolution and/or closing another applications that are running. Exiting..." and the game shut down. How can I fix that to play the game? there's any option to lower the graphic of the game? When I played the demo, it was working normally.
