fireflies on grass

[super gnu]

im getting tiny bright hilites on my forestpack grass as ithe cam moves. i assume its reflections of the sun. i tried "clamp output", and turning max ray intensity down in increments to 1, but neither seem to make any difference at all. in fact the image is identical when overlaid in photoshop with original.

does this mean these settings dont work with gpu (in which case why were they added to interface?) how to fix?

Might want to post your material setup as well.

to be honest its just a forestpack grass preset. ive not touched the materials.. i know it has some reflection.

As I just upgraded my gear I'm also trying out gpu as it is soooo much quicker. Unfortunately I am also seeing immediate and non-solving fieflies on stuff that is really quite simple.
I have yet to test it thoroughly so it may be user error. My visual errors also involve Forest but they don't stop there.
