From the article I noticed they were using Nvidia’s FCAT VR benchmarking thing. I had another look at it, and was going to write something up on using it in a series of posts I like to call either ‘How to Not Play Flight Sims in VR using Other Pointless Tools’ or ‘@smokinhole’s I Don’t Understand The Question, And I Won’t Respond To It VR Tech Series’ (kidding man, I love you!). 
Unfortunately it looks like FCAT hasn’t been updated since 2017 and while it provides some good underlying metrics through some event hooks in Oculus and OpenVR, it’s not as good for a quick settings benchmark comparisons as CapFrameX - CapFrameX - Driver Comparison 457.30 vs 466.11 for DCS 2.7 & MSFS VR
