It's a perfectly valid point he made and one that most people tend to make, I rather have all the performance I can get when talking about the 30-60/70 fps range i.e. such as in control, cp2077, metro etc. than have more performance in the 120+ range i.e. as per hitman
Even in AMD sponsored titles, amd cards take a big hit in performance when RT gets turned on:

FSR is not in the same league as DLSS and is not really meant to be compared to dlss, if anything, it's better to compare nvidias NIS to FSR (amd have said this themselves). Once RDNA 3 comes out, we'll see amds real competitor to DLSS.
Also, not 100% confirmed but it seems like amd aren't even properly rendering ray tracing in games either, some guy pointed out the problems in this recent comparison and said he noticed the same as well as in watch dogs legion, would be interesting to see some more in depth analysis on this and if it is an issue with amds RT hardware or/and amd drivers or/and the games ray tracing implementation or if it is a system end issue....
But might be worth bearing in mind if you want better image "quality".
