3.0.1.1120: crossfading uses more than 50% process [F4203]

Hello guys, i just noticed that this evening while i was writing on msn:
When MM passes by from one song to the next one on the playlist (cross fading system), it leads to make slower my pc, during one or 2 seconds.
When the new song is played, no problem anymore, until the next song's crossfading, where the problem appears again.
I observed the phenomenon with the task manager processus, and i saw it used until 56% process during thoses 2 seconds.
It never happenned with the previous builts of MM.
Did someone else notice that?
Thank you!

Pastis,
Can you re-verify that earlier builds (e.g. RC2/RC3) don't experience this problem on your machine. Also, can you see whether disabling hardware acceleration, OR switching to waveout output plugin solves the problem?
Note: I do see a crossfading-related spike, but that's related to filling the buffer.

Hello, Rusty. Happy Christmas + thanks for MM + I hope you get to put your feet up soon. I've got the same problem. Didn't report it bcos I thought it was my computer's fault. I haven't got crossfading ticked in the play menu btw.
I changed to wave output but the behaviour is still the same. It spikes on change and then stays spiked for a second or two when the new song has started too.
I think this is a very new thing - maybe RC4/5; sorry, I can't be sure. I don't know what hardware acceleration is, so I'll leave that to someone else till I find out!
Good luck.

Proper answer (forget previous post):
I get a spike up to c. 60% in CPU usage when MM changes to the next song.
It happens with and without crossfade, with and without hardware acceleration and also with the waveout output plugin. I also tried it with all the boxes at the bottom unchecked too.
You cannot click on anything else for the three seconds or so this process takes - the program 'seizes up' if you do (but usually comes out of that state when you wait).
CPU spike

Will be fixed in RC6.
Thx.

Indeed loool sorry
But what wrong idea people could have reading "testes"? Because the word "teste" doesn't exist in english. I didn't find it in dictionnaries...
EDIT:
OK i understood
