It depends on the games tested - I play quite a lot of FO4 and the overclocked SKL/KL CPUs are by far the fastest for the game,even compared to Haswell CPUs were there are some decent gains. Especially in its modded form it can really push some cores quite a bit and seems to be massively bottlenecked by memory bandwidth,even though it does show some limited scaling to more cores. Its sadly the consequence of Bethesda using the Creation engine which is off shoot of the Gamebryo engine released in the early 1990s(!).
Usually it isn't an issue for a normal playthrough as the engine is capped to 60FPS,which means even an older CPU like an SB/IB Core i5 would be fine,but once you start modding the game and/or start building large settlements with the DLC packs it can start to show how poorly optimised an engine it is. Even AdoredTV kind of noticed it as one of the worse games on Ryzen - I suspect Bethesda could extract some extra performance if they cared,but the same thing happened with Skyrim when it took the community themselves to optimise it to run better especially on AMD CPUs.
OTH,something like BF1 MP or even the Witcher 3 ,or any of the games based on newer engines Ryzen performs very strongly in and this why the Ryzen 5 1600 is one of the best value gaming CPUs in the last few years.
