No, filesize and ram usage aren't related at all (you know it :p ), but half
the times I've seen rendering issues spawning from a simple change in file
formats or file locations it was because of a slow network.
moving from JPG (smallest filesize of the formats you could use from XSI) to
MAP (possibly the largest) would make a consistant difference if you were
broadcasting the texture or accessing the same storage from all the boxes
thru a mapped drive or aliasing.

Does filesize on disk really correlate with how much ram MR uses, isn't
map the sort of format MR keeps the images as in ram anyway?
