The new update, to me, fixes the no longer use of the "increase contrast" to improve performance while gaming. Of course Reduce Motion is on, but before having increase contrast made it super choppy and I could play a single 3-D game with 7.0.3, but now, I have it turned off to bring back that blurred effect instead of that black dark it got switched out for, and it doesn't lag anymore. I think that was one of the improvements they've made in the new firmware.
I know ios 7 is for redesigned everything but what I am waiting for is an update to move every ios 6 designed apps, web, bar on the bottom screen (where 4 apps are organized on iphone), siri, and anything else from ios 6 to be moved to this version so everyone can switch between old and new looks to organize ios 7 how they want it either way!
