Irradiance map precalc at "High", but then render on "Low" for render.

What effect would it have if I precalculate an animation on the “High” preset, but then when I actually render, set it to “low”?

Would it:
A) Be the same as precalcing at low and rendering at low?
B) Still render at “High” even though you set it to low?
C) Render low but with good quality and speed since the precalc was High?
D) None of the above?

Anybody know for sure what it will do?

mm if youve precalculated the map at high, changing the settings after wont make any difference. except perhaps the interpolation parameter, which im not sure is adjusted by the presets.
