No. It seems everyone who plays overwatch is getting shafted. The IPC on the Ryzen cpus is right at skylake levels, so you are pretty much about 10% behind brand new CoffeeLake, that's it. With a decent OC and high speed ram, you can get @20% performance increase, which puts IPC either at or above stock CoffeeLake levels, so for all intents and purposes Ryzen and CoffeeLake makes no difference there.
As far as I can tell from reading all the other forums, from battlenet to reddit, here to Linus tech, it's a game issue, not a pc issue. If you ran Ashes of the Singularity, you'd be lucky to get 40-60fps even with an 8700k and 1080ti. Just like windows CE, the update funked things for everyone.
