"Disable Desktop Composition"- Helps FPS?

[Ransome]

Hey,
I just happened to disable desktop composition on the Ghost Recon FS exe. file, since it was suppose to help with crashes and bugs.

I recently read this, however:

I wonder how significant is this "performance bump", is it useful for gaming?
Can it truly increase FPS? or perhaps ensure better stability and less FPS dips?

I am talking about hardcore gaming rigs.

thx

And also, should I "disable visual theme" as well in the compatibility tab of all my games exe.files does it help?
