Hi Farshid, I did all the testing on PreciptiationEffects on my dual GPU, dual core machine and it scales just fine.
When you same combining PreciptiionEffect and CameraNode how are you combining them? RTT effect? Multiple window/multiple graphics contexts? The draw time going through the roof would tend suggest the driver falling back to software path, or perhaps serious memory thrashing issues. The PrecipitationEffect is designed to scale well, much more than an CPU based particle effect code, with it reusing the same geometry over and over to avoid any issues with memory space or throughput. The fact it isn't suggest to me that its most probably falling back to software path. The only other thing I could guess is think of is that fill rate is a serious issue, but this would be something that would occur most of the time.
