He is saying that due to the device fragmentation, users have the option to change their graphics settings, just like on a PC and that is a GREAT thing. The only reason users can do so is due to device fragmentation. With that said, thanks to device fragmentation for giving us the ability to adjust our graphical settings on our phones.
I wish all games on phones would allow us to change the graphical settings. We should be able to ensure that our games run the best on the hardware that we have. Nothing is worse than having a powerful device and a game that has been coded to display low resolution textures and low polygon models because the developer did not code the game to scale to the performance of your phone's GPU and RAM configuration.
Beach Buggy Racing allows us to change many graphical effects such as resolution, Lens splash fx, boost blur, color correction, water reflection, water normal map, hi-res water mesh, v-sync 60hz, hi-res models, hi-res textures, scene complexity and more. Now THAT is how you add graphical settings to a mobile game! They can take my money!
