Personally, I wouldn't have any issues with it, but the fact that using a * instead of / probably loses a few ULPS and I'm not sure that is what we want for inside of the game engine. It is still faster than the standard method even using / , but by doing the - in a separate operation there is probably some ULPS loss there as well.
