Particle Density
 

Has anyone increased this past 100 to achieve better graphics.
I have put mine to 200 but haven't noticed anything.
I guess it wouldn't do anything if the 100 is a percentage number but it dos not say.
Changing the resolution txt in the same file didn't work in the past so don't know if it could improve things if I do it correctly, maybe I'm not doing it right?

I can't answer your question, Maky...but...were are you doing this??

I'm running windows 7 so your location may be different under a different OS.
Open it with notepad.
