Yes, I've been following this too. There are people reporting sudden framerate drops from 30+ to single digits who aren't even using SkyMaxx Pro at all, so I'm starting to wonder if SMP's being falsely accused in many cases.
Still, if you're not using FSGRW, updating to SkyMaxx Pro 3.3.1 is still a good idea. It fixes any situations I can find within SMP that might cause performance to suddenly tank for no apparent reason.
I automatically accept all Windows 10 updates and am not seeing this myself though, so whatever's really going on would seem to be complicated.
