I tried the Chrome fix where I set Max Flags to 512MB, still stutters though.
UC Browser mini
Vertical scrolling is undoubtedly smoothest on Firefox (flawless), hands down. Second place would be Lightning Browser (very slight barely noticeable Microlags while scrolling during image rendering) and third is a tossup between Maxthon and Boat browser. I have to mention that Maxthon has a very inconsistent input lag for example if you scroll fast, stop the scroll and scroll again slow, it feels VERY unresponsive to me.
The Mini versions are very smooth but make scrolling through long lists (i.e Facebook newsfeed) annoying as I keep having to click on show more, and wait for the loading time every time I scroll to the bottom where as in the full versions it pre renders before I reach the bottom, making the loading time minimal.
Thanks for the help guys.
