Hi,

is POV-Ray's "Render Priority" the same setting as inside the Windows
Task Manager's process window its "Set Priority" setting for running
processes? I use Windows 7.

The Windows Task Manager offers
- Real Time
- High
- Above Normal
- Normal
- Below Normal
- Low

POV-Ray offers:
- High
- Normal
- Low
- Background

If both are about the same CPU feature, to which Task Window priority
option does each POV-Ray render priority option correspond to? Thanks.

Task Manager    POV-Ray
----------------------------
Real Time       -
High            -
Above Normal    High
Normal          Normal
Below Normal    -
Low             Low
-               Background

POV-Ray's "Background" mode does not only lower the CPU scheduling
priority, but also the resource scheduling priority.

In my case, the relations are as follow:
Pov	Task manager
High	High
Normal	Below normal
Low	Low
background	a bit above idle process

On a single core CPU.

Thanks both of you. The answers helped me: now I know, that I don't need
to change both of them, but only one. :-)
