Hmmm ... my PIII comes up with this compositor warning:
"Your screen does not support OpenGL. Falling back to software engine"
It seems it doesn't like the Radeon Mobility M6 LY that this old laptop is
running. I don't recall having this problem before. I should try a later
snapshot to see if it persists.
I can see in top enlightenment runs between 3.4 - 5% of the CPU with bursts up
to 35.9 - 54% when I move between windows (a couple of aterms and a xterm).
Without composite enlightenment shows between 0.5 - 2.5% of the CPU with
bursts up to 7.9% when I move between windows.
So, yes it is usable, but if I am doing something heavy on this little box
like compiling, compressing files, etc, then it slows down noticeably and this
is why I would rather give up compositing effects for functionality.
Are there some settings in the composite configuration, which will minimise the
load?
