To all ye Pyros - The Starburster
This preset is a modified version of the first preset I posted. If anyone out there loves looking at fire, I suggest this one to you. I'd really like to know what everyone thinks of it. Any hints, tips, or other help is also appreciated.
I mess around with AVS when I find time, which isn't that often, but I think I'm figuring it out alright. Most of the time I just end up typing in random expressions and see what happens. :)

you seriously need to optimize that!
for example:
you use an effect list with input=multiply as the first component inside an effect list with clear screen enabled.
multiply is not a very cheap filter, and you might as well activate clear screen on the inner effect list and set its input mode to Ignore.

here's some useless filters :)
the first parameter is always the current screen while the second parameter is the effect list content.
0 means that current screen is completely black.
These combinations can be substituted by "Replace" blending:
xor(0,something)=something
maximum(0,something)=something
subtractive2(0,something)=something
additive(0,something)=something

These combinations can be substituted by blend mode=ignore+ a clear screen:
subtractive1(0,something)=0
minimum(0,something)=0
multiply(0,something)=0

here's the "filter-optimized" version ;)
i also added a first frame only clear screen to light grey to make it less flickery in the first seconds

Thanks for the help, the fps has dramatically increased.:up:

I guess I didn't realize what I was doing with the multiply and xoring, way too extraneous, huh.
Anyway I messed with it a little so here is it now.

this one is too flickery imo...
flickery things are bad for the eyes, which is why most ppl dont like them

also, you used a convolution filter with a scaling of 15.
use scalings of 1 2 4 8 16 32 and so on for best performance

Ok, made this thing much better. I fixed the convo filter, using a scaling of 16 as TommyLobo mentioned. ;) I then cut down the flickering as much as possible, so as not to strain the eyes. Also, I added a superscope (pulsar) thanks to Elvis' 3D superscopes package.

That is a LOT better. It's actually rather nice now, like a particularly peppy sunflower.
