Actually there are plenty of gamers that do have an interest in graphical improvements & or comparisons because those gamers want to make sure their getting the very best graphics from their games that can produced from the hardware specs so everyone of their games they purchased is worth every last dollar spent on each.
I do agree. but there is not much footage of GT6 at the moment and any slight gameplay video is a plus in my book. I'm a huge GT fan. and seriously, if anybody can't see the graphical improvement even via camera/off-screen, then they need to get their eyes checked. I mean it looks wayyy smoother than GT 5 even though GT 5 is running in 1080. There are no jaggies off in the distance that create that weird choppiness.
From this video I can only assume that GT6 will be a decent improvement over GT5.
