Most games do not need 60FPS. Drive Club even proves that racing games don't require 60FPS. It may help with some racing games, but it is not a necessity.
Racing games don't need textures, or greater than about 192 x 144 resolution. They don't even need to use polygons. They don't even need colour.
What's with you comparing 60 fps as a necessity against things that are very definitely just "un-necessary" personal preferences?
If I had a PS4 Pro, I'd avoid any game that didn't allow me a 1080P and 30FPS option that had better graphics and not just downsampled from a higher resolution.
Then you'd be stuck with the none pro versions that looked worse at 1080p. Hooray! A winner is you!
