Closing applications to increase FPS

[switchguy0]

Hey. First post here. I am wondering if while playing a game in fullscreen does the graphics card still need to generate the desktop and other application GUI's? I just figured if it does then disabling aero while playing Crysis would give an increase to FPS?

The CPU, RAM etc are better than the GPU so if there is a bottleneck then the graphics unit is it.

When in fullscreen your GPU is only working on the image you're seeing. This is why when you play something in windowed mode you often get much less FPS, even if you're running the game at a smaller res.

It's the CPU that benefits from closing applications in the background.
