To be honest I haven't really got dirty on the command line yet, I was 
more interested in out-of-the-box functionality in-so-far as the 
distro's X capabilities were concerned.

As I said before, 3D acceleration is not available at this time, this is 
something I believe they imposed so that PS2 emulation is not possible. 
It's always possible that it will become available but I've not heard of 
anything yet.

Utilising the vram as swap effectively adds ram. So general performance 
is fine. It's when you do something gpu intensive that the cpus load up 
and the system slows down significantly. Openoffice and printing work 
fine though :)

So as for the specifics, I can't say much. I haven't looked at the 
available CPUs but gkrellm was only reporting 2 at the time. If I get a 
chance I might delve deeper and revisit this thread but no promises :)

I get the impression, though this is speculative, that YDL utilises more 
of the system. Or maybe it just does it better. Either way the 
experience is more polished.
