Seems some people are misunderstanding what I'm saying here. I'm not here to debate the fact that there is a greater draw distance or high res or the fact that PD took more time to develop GT sport or anything like that. I'm here saying no Forza does not beat GTS in car models and textures. Perhaps an image will better explain what I mean. For example look at the front of the McLaren 650S
Real car:
Notice how bad the Forza model texture is? The top of the grill is just completely wrong and going all over the place because they have slapped a generic texture on it and said 'f*** it that's good enough'. look at the bottom where the texture meets the spoiler too. They are like this with their shaders too. High res Fresnel but no actual effort put into modeling details of the materials
So while I completely understand that a game might get things afforded to it by Ultra PC settings etc no amount of horse power will fix the disparity in detail between the games. No amount of 4K Ultra PC settings will fix that grill.
A crap 4k 10mb texture is still a crap texture. Using a bad high LoD car model is still a bad car model. What I said was high res/high poly does not a good model/texture make. They are still sloppy.
