Particle System: Size of Particles Limited?

Hi there!
Currently I'm playing around with Unity's particle system. One major limitation I have come across is the size limit for particles. It seems that the "Initial Size" setting only works until a value of 6.0. After that the particles just won't get any bigger.

Is this a bug or a feature? ;-)
Is there any way I can make my particles bigger?

PS: I also tried increasing the resolution of my sprite's texture. That did not help.

 

Check the renderer section of Particle System to see if it's limiting max screen size in there, it could be 0.5, which means a particle isn't allowed to get bigger than half the screen size.

This is a fill rate saving measure you can edit.

 

That totally solved it. Now my particles can get as big as I want them to be
Thanks!
