This is cool for a few reasons. Firstly, it was produced by an enterprising member of the CVG community. Secondly, we were going to do this anyway so someone has saved us a lot of work. Thirdly, the video comparison itself is pretty neat if you're into that sort of thing.
According to CVG regular only_777 (real name Simon): "I thought it might be fun to make a video that shows the difference between GT5 and GT6. I've used the same track and put both videos side by side so everyone can see both games running next to each other.
"This video shows the difference between GT5 and GT6 in terms of graphics by using the Big Valley East reverse stage as a yard stick."
Nice one Simon!
