I understand the need to "head off people reporting issues," and I'm sure that you're not referring to me in particular. Personally, I'm aware of how the weather radar functions. I've spend the past several months reading that section of the manual in preparation for the release. I'm far from an expert, but I have taken the time to educate myself. Networking ASN has its advantages, even if the performance impact is not huge, every little bit helps. I do get better performance when I run ASN on the second computer. In addition to the better performance, being able to control/analyze the weather from a second computer, without having to minimize or pause the sim is perhaps the biggest advantage. I can keep a eye on (change) the weather at my destination, my alternate, ect, all without having to pause and minimize the sim. Not only is this more realistic in terms of what would be happening in a real cockpit, but I've found that FSX really does not like it when you minimize it or use other programs while it is running. Also, I run PFPX on the second computer, PFPX can pull the weather from ASN directly which is an excellent feature. Yes, setting it all up to run on the second machine was not easy, but it was certainly worth it. I'd rather not have the weather radar feature, than move ASN back to the primary machine.
I can assure you that ASN is sending precip data to the sim, the rain is visible out the window, but not on the radar.
Has the weather radar worked successfully when ASN is networked? If the answer is no, life goes on. The improvements to the flight dynamics are the highlight of this update anyway. If you could point me in a direction to work in so I can solve this issue that would be great too.
