EA Sports has released a new blog that focuses on positive reaction to the graphical improvements in NCAA Football 11 that came with the release of the first screenshot. They have also included two new screens (which can be found in the gallery) along with a comparison to NCAA 10 which really shows off the difference well. You can check it out in its entirety here.
Without getting too much into the art/technical details, we wanted to talk about a couple of graphic improvements; the first  being linear lighting. This lighting technique allows us to more accurately control the material properties of everything that makes up the player. To put it in basic terms, we now have control over how bright or dark things get without losing detail. It also helps us get the authentic color on the uniforms.
So far, although there have only been a few screens and their focus has been completely different, I think the NCAA 11 shots have represented better than those out for Madden 11. I don’t believe there will be a big discrepancy in graphics between the two games but the NCAA side has put out the more impressive ones so far. Make sure to leave your thoughts on the blog and screenshots in the comments!
