Some pictures from pCARS which I think is not close to what GT5 already is and what possible GT6 could be IF it is on PS4.
Still this is all MAXED out...there is no more than what I put in the settings, photorealistic HDR, SMAA X2, all effects possible, at 1080p...etc. (My PC almost died, lol)
Do you really still think that the footage is in-game?
I think lighting and other stuff such as shaders and so on are way better in GT5 than pCARS. Textures are way exaggerated, and overall effects (in pCARS)... and as you can see you can tell the difference between something real (GT 15th anniversary footage) and the game. Also the models are not as accurate as it can be.
PD are Gods to make graphics we all know that but that footage is real. All the things that people think that are "effects", are just because of the HD cameras and sun reflections, lens effects (focus) and such.
The only CG there are the ghost cars.
Colours, the level of saturation and tons of realistic details are way too hard to reproduce on a 3D and real time image in motion.
Go and look at GT5 again...check SPA which is the best circuit in the game and compare it to that. (Of Course Nürburgring too)
Textures and minor details are more noticeable when something is not real.
