Hi,
Here are my results using Olaf's benchmark patch:
Pd 0.37.0, Pentium 4-Mobile 2GHz, winXP, with RME Multiface using ASIO
drivers at 70ms of latency.
Pd.exe priority set to real-time in task manager. Wish83.exe priority left
at normal.
I got 745 instances of osc~ before I could barely use the GUI. No audio
dropouts.
At 750 instances the computer froze, but still without any audio drop-outs.
The audio performance improvement using real-time priority for Pd.exe was
quite impressive. While using Pd at normal priority I was getting
occassional audio dropouts when using the GUI at about 330 instances of
osc~.
