The images are rather small.

Do you need the depth of field and motion blur on the cameras? That might slow things up. The DMC image sampler max subs I usually leave at 4. In the Color Mapping turning on the Sub-pixel mapping might help. The Irradiance map HSph. subdivs should probably be left at default 50, 20 seems low. The Catmull Rom sharpening filter might make noise more apparent also.

I believe checking "sub-pixel mapping" and "Clamp output" under ColorMapping should fix the spots.

i follow dlparisi !

checking "sub-pixel mapping" ON can solve your problem.

And what are the pros an cons by using clamp out and sub pixel mapping ? when i use it I always recevie a warning in the vray dialog so I always prefer not to use it.

Thx
