Ok so the update (at least on Series X) has improved graphics a lot (IMO) certainly has a nice smooth look to the graphics both in looks and movement, however as for the claimed 60fps I will caveat this by saying it’s most but not all off the time , effectively it’s not a locked 60fps.
It’s great that you can now race in glorious sunlight without the framerate tanking , albeit it does show hints of slow down still, some circuits are better than others. I used to find B/Hatch took a major hit but now it’s more than playable however Oulton Park is worse, even resorting to only 22 cars (21 + me) and running on a cloudy day it still exhibits slowdown to the extent I can’t play it.
However chasing down cars around Donington with the sun glinting off the cars is quite spectacular now and overall it feels like the car response is smoother input wise.
So it’s got some way to go still, I hope they can utilise the FSR element of the S/X chip in version 1.8 so we get the same performance increase that the pc version received albeit something tells me we may not, either way some extra optimisation is needed at present, not tried any online yet but I understand there’s issues there still also.
