It's indeed written in EXA man pages that it's the default, and as you've written it shouldn't make any difference....it shouldn't but it DOES.
Actually, without the ExaNoComposite option, the driver registered the composite operation (render acceleration), but once you use that option, you can read in the xorg log file: "EXA: Disabling Composite operation (RENDER acceleration)". Moreover it doesn't matter whether you use "false" or "true", they both disable the composite operation...looks like a bug to me...
Sorry for the digression :-)
