Best approach for very low-lit scenes?

Pretty simple question (I think)...

 

Lately I've been doing some fairly dark scenes and noticing a lot of ugly noise/blotches/shadows. See example:

 

008.jpg

(might want to click on this and choose 'view image' from the r-click menu to see full quality)

 

This is on just about the highest settings (IRR high, 3000 LC, noise 0.005, DMC 2/8) and shadow samples around 24. There's one direct light coming in through the window, a fill light pointing down from the roof (vray plane light and fairly dim just to take the edge off the darkness) and that test light on the left to see how torch light will look but just ignore that for now.

 

I'm guessing that it's just so dark that there isn't enough info in the picture to give me anything but ugly noise in the corners? And I'll have to brighten up the scene and darken it in post?

 

Also, AO isn't turned on in case you thought it was that.

I have to do a fair bit of casino projects so i get to do a lot of images with dark corners. I find that simply increasing the Hsph. subdivs and interp. samples in the IR map section works, i'll double them both to start and that is normally enough to keep the dark style but without the splotches.
