And yet it mostly launched with games that I could play on my 5-year old $200 GPU that I probably couldn't even sell for scrap at this point. People really overestimate how much of a GPU you need to play a lot of these games. Sure, if you have a 4k monitor and you want to play at 144hz then sure, but at that point you've spent $2000 on the monitor, so what's $500 on the CPU.
And if you're willing to take upscaled resolutions like Stadia offers then you can typically go below the minimum specs (which are themselves far below recommended). Direct X versions are more likely to be a blocker than simply not being able to maintain a framerate.
And in my mind, those are enthusiast games, because only enthusiasts are spending $500 on a graphics card.
