 ultrafast is the fastest.

Thanks for the advice, I would love to give it a try, but it seems that
after recent clean-up there are no longer such presets available in tree.
Rather there are new preset format now in the "preset" tree.

So is it safe to use "old" presets, or anything new can be suggested?

Thanks again.
