I am on Pd-0.39.2-extended-test7 on Mac/PowerPC and it seems smooth  
to me too.  I can see know difference whether I am holding down a key  
or not, or wether the DSP is on or not.

One thing, you are updating every 5 ms.  Your screen probably has a  
refresh rate of around 12.5ms (80Hz) or less, so that's 2.5 position  
updates per draw update.  That could make things less that smooth, I  
suppose.
