Can I suggest a script which runs all the standard examples, saves as plmeta files, then re-renders using the psc driver. It would be illuminating to compare with the direct psc driver and should also highlight any missing API elements in the buffering.
I'll see if I can knock something together. Andrew Note Maurice's comments about not completely reproducing the original device, but again it would be good to quantify that.
