I have a dual monitor setup on my mac pro. I didn't like having my second monitor on when I was running games, so I installed SwitchResX, which allows me to deactivate my second monitor. Does anyone know if this frees up video memory for the game? I emailed the creator of the program, and asked him if he knew if this would free up video ram for my other programs, but he did not know. He said that this would release the frame buffer, but wasn't sure if this meant that all of the card's video ram was released to handle the one monitor. I am skeptical that it does, because the system profiler still sees the second monitor, and says that it is online.
