I went and tried the settings suggested. My PC runs with an Intel i5 12600KF, 32 GB of DDR4 memory and an RTX 4070 Super. For driving solo, I'm getting between 100-120 fps at 1440p resolution, and from 90-110 fps when racing with say, 15 other AI cars. Visuals look good, no stutters or extreme frame drops that I can see.
But I turned DLAA on and the aliasing is so much better, and races now average 130 fps, and the replays average between 100-120 fps and look great. I don't think the veil type is mentioned in the article, but I've been using the cinematic one, which gives it a "GT" type look.
