Could u be a little bit more specific at what 'features' you're talking about?

Chronon:
EQ.  Peakmeters (in the WPS) have caused problems.  Crossfeed, probably.  Basically you want to disable as much DSP as possible to see if the codec will play in real time by itself.

JamFreak,

A good way to figure out how much CPU load each codec is reponsible for at a variety or bitrates on your aprticular platform you could perform the tests described in this page:

If you do these tests please contribute some Codec Performance numbers to the wiki page as it would be of great help. So far I'm the only one that has bothered with this.

Eventually we will have a better test involving a decoder plugin which will spit out a detailed logfile, but until then this is the only information we have.
