i don't know if it's helping or not, but i already have nitrous installed, and another tweak (don't remember name) for speeding up animation. animation is definitely faster, but i didn't have issue with slow animation before anyway. my problem is
animation stutter where the animation for going home after using an app for awhile stutters badly. after i've sped up the animation, it seems like now the stutter is worse, because the duration of animation for going home is shorter, there doesn't seem like any animation when this stutter occurs. it just looks really bad. not all apps cause this. the apps that cause this stutter when going home most often are Safari, Youtube, FB, G+, Aliexpress HD, and more. after extensively using these for an hour or more, the animation for going to home screen stutters on iPad 3 with iOS 7.1.
Also, I saw someone with iPod touch 5th gen started a thread on apple communities and he/she was having the same problem on iPod touch.
If you guys read this thread

from start to end (only 2 pages), you'll see other iPad 3 users also have this problem. Some don't because they don't use their iPad 3 extensively.
So is there maybe another tweak that can smoothen out all the animations in the system or something, and prevent stutter, maybe by optimizing the code better for iPad 3?
