Not the case with VR. Especially Fallout 4 and Skyrim as I've encountered.
I'm into VR just now and run a 1950x. No problems or low framerate to report.
It's different now because in the past AMD's best would struggle to get the framerates to give a smooth experience even compared with Intels I3 CPUs.
The misconception for me is that you need that extra oomf for the games when in reality by the time you need it the games will probably be on 8+ cores anyway.
Now it's more like Bugatti Veyron vs Lamborghini Aventador. Sure Bugatti is faster but the Lambo is no slouch either.
My theory.
