Rain shaders, AO and certain particle effects were never fixed to match the console version. Ya I’m referring to the stuttering when traversing the city.What visual aspects? Very difficult to tell as it's still 1080p on consoles so it's a flickering mess, but I don't see any rendering differences, other than the benefits the Nvidia extensions add, which can be substantial. On my 12400/3060 I will occasionally see a drop to 59fps when it's not GPU limited when driving and boosting, but that's about it.
A 1060 was giving ~80fps at 1080p with all Nvidia effects on, while the streaming issues at high framerates could still be an issue, at least the rendering prowess fell in line with the expected difference between a 1060 and the GCN GPU in the PS4. Here, we're looking at a 1060 needed to basically match the PS4 which is nuts.
Have you seen any reviews that actually benched a 1060? If so can you link.
