Unfortunately you'll be doing quite a bit more waiting with this filter, it's abominably slow.
I actually made this filter a long time ago, before almost every other filter I've submitted, back with Filter Forge v1, the reason I've never submitted before is it was too slow to render all the presets, I've only been able to submit it now because I've upgraded from a Core2 Duo at 2.0Ghz to an AMD FX8310 overclocked at 4Ghz, still takes over 6 mins to render the default image.
The internals are a huge complicated mess, I've tried tweaking but I can't find anything that can be done to speed it up without losing the metallic effect, so just enjoy it in all it's super slow glory.
Release the Mongoose!
