My takeaway is that most games look playable even on lower settings. Also, now I want a whole thread dedicated to "guess the graphics preset", if only to distract me from the wonderful

I was going to challenge your claim about how long it's taking for each leap in hardware. I recently compiled a list of
my last 25 years of graphics cards and I was surprised at how consistently my upgrades gained +200% performance for roughly +50% power consumption. But I looked up release dates of the cards and, sure enough, I'm waiting longer each time. 2.5 years between upgrades through the 2000's, but then 5 years and 6 years between upgrades in the 2010's.
(OT: it was hard to find benchmarks for old products. Other than TPU, TomsHardware, and Anandtech, every other review site is linkrotted or entirely gone, and many performance graphs were not backed up by the Internet Archive.)
