It's 2xMSAA in-game and 4xMSAA in replays. The bright light reflections ramping up edge contrasts, and specular aliasing make it seem worse. Also it looks like the road surface gets a healthy dose of AF but nothing on the road sides.
I wasn't on the roads much, maybe that was the problem. The side bumpy pavement had really bad mip lines, if that is the term. I also didn't notice any IQ improvement in the replay, but I'll look again.
What happened to "free" 4x AA using tiling, this is a 1st party game and 16 months after launch.
