Most of these have probably been noticed before but just a small list of quick visual glitches:
GT6 never seems to like loading distant parts of the track, Brands hatch this happens a lot, Streets of Willow the Distant part of the track disappears, but Sarthe is the worst offender with you being able to see the track dissapear behind you on the main straight!
A small shadow shading issue with the Infiniti FX45
Night shading is just odd on certain cars, especially white cars.
Nissan Z31, the wheels don't have any reflectivity or texture at night.
That gradient banding!
Please tell me this wasn't meant to be a final texture, it is dire.
No self shading on most car's wheels and no shading on chrome like surfaces.
Good to see the suspension model working in photomode.
A few minor ones here, but it can still ruin a picture.
So they use volumetric lighting but can't use volumetric shadowing in photomode, that would fix most of the issue here.
Oh, and the Diablo GT2's side panels light up at night along with the lights.
