Check out this simple example of a perlin noise being blurred with a mere radius of 1 and then plugged into a scale component. At 100% scale, the result time is as expected. But the more you scale it down, the slower it gets.

According to my calculations, a rendering at 1/8 scale (or 12.5%) takes ~50 times longer to render!!!! smile:evil:

What is the reason for this, and what is the workaround I can use to prevent this from affecting my filters?

Blur to Scale (small) = SLOW.ffxml

This is because the Scale causes the internal bitmap of the blur component to be much larger (so it does not loose detail precision if you zoom in again). Put the Scale before the Blur and you'll see no difference in processing time.

when the value of Scale approaches zero, Filter Forge will consume all available RAM and crash.

If wishes were horses... there'd be a whole lot of horse crap to clean up!

I loaded your filter, adjusted some settings, hit Next Variant a couple of times — and got no tadaaa. What are the steps to reproduce your issue?

Dear Sir
Next variant may not help.

This filter was meant to have a greater control over blur so that we can blur things with greater control.
This reply was posted with my understanding that the person asking question (Indigo Ray) asked for how to get a greater control on blur and therefore he first scaled up ,blurred image and then scaled down (Somewhat like that). I am not yet confirmed that was the real question!
