I do have 2 gig, but looking at the screenshot of elemantal to be attached I
see that used and requested differ.

This shot doesn't really show how long the pauses are - they are really bad, it
takes about 2 minutes to render the first few frames with pauses of many
seconds after that.

It's so bad it's hard to tell whether the revert helps - probably not, I guess
it's something different. Have you tried Elemental?
