I don't know if this has been suggested before, I noticed in X-Plane11 I was receiving some random stutters, just every now and then.  I know there are a lot of souls out there with nothing better to do but to ping systems.  So finally I decided to block inbound Network Discovery, all the entries, as well as Remote Desktop Assistance.  X-Plane11's stutters went away, just like that, and it seems fps went up as well.

Might be a Placebo effect, but I thought I would post...

When you said you blocked all of them, how did you do that and do you know if it might affect something else?

Good question.  I've been testing for a few hours and so far nothing seems to be affected.  I'll turn it on again and compare.

Interesting, will have to give that a try.  

Are you behind a NAT gateway? (ie. does your IP address start with 192.168, 172.16-31, or 10)?

If so, then this didn't do what you think. Besides, a ping is around 60 bytes. If you're getting any noticeable CPU load handling tiny UDP traffic, your sim must be a slide show. :) If your sim slows back down when you turn it on, then I'd look inwards, to your own network.
