Generally, the intention is for the defaults to be safest, and changing
them incurs a certain risk.

The default may be too small for demanding 3D applications with the r300
Mesa driver.

It can cause problems on some hardware setups.

The purpose is to save power by automatically disabling the clocks of
idle GPU blocks. This can't increase performance but may decrease it
slightly in some situations.

I wouldn't use this on your machine, it's mainly for powerpc machines
where legacy VGA access just doesn't work.

As of X.org 7.3, compiz should be faster with EXA than with XAA with the
r300 Mesa driver.
