Hey all, as the title says, a very quick/rough comparison of HD vs normal. The video is here: http://youtu.be/6uX9MnG-pgA (4k res still processing at the time of posting) and you can see the comparison screen about half way down this page (look for the yellow cars): http://www.hardwareheaven.com/2014/06/grid-autosport-video-review-and-4k-gallery/ Summary: Yes the camera angle is a little different but the HD textures do improve the cars. How noticeable will it be at 100MPH? Probably not that noticeable... but improvements are improvements...
