While not related to the updated features, this was the winpov64 I used.
Using a newer computer and going though some older scenes.


With no included Work_Threads, or commented out, Work_Threads

Render Time:
   Photon Time:      No photons
   Radiosity Time:   No radiosity
   Trace Time:       0 hours 22 minutes  9 seconds (1329.351 seconds)
               using 3 thread(s) with 3988.077 CPU-seconds total

Render averaged 2433.55 PPS (811.35 PPS CPU time) over 3240000 pixels.

Adding:
Work_Threads = 32
To my .INI file gave me the following outputs.

Is there a default some where?

WinPov editor:
Render/Thread Count is set to 32
