Hmm I dont see how a replay ss with high brightness/contrast and mb covering all detail except the car will invalidate the ingame ss. And talking about the new car game the ss posted is ingame play but got some mb.
He posted undoctored ingame play screenshots. Give or take brightness/contrast setting for different HDTV setups. For example teh replay ss by Dantruon looksto have way to high brightness/contrast to give more life like lighting but looks overdone. PErhaps it is a photo offscreen becouse thoose tend to have more brightness/contrast (mostly to much) due how the camera captures the surrouding light (and if flash is used).
Still I think the cars in GT5 has a bit more detail ingame. <-- Scratch that, after watching the video I got to give it to GRID.
Thats not GT5 Prologue.
