TouchWiz gallery scroll lag demo
So Optimus UI had not have THAT kind of lag in their 4.1.2 ROM on OG Pro. What had changed?
Now, what I've come to conclusion is that these lags and stutters are caused by bad CPU governor used, like "ondemand" instead of "interactive". And second reason is too short polling interval, CPU drops frequency too fast and lowered CPU frequency while scrolling causes stutters and hickups. Somebody posted in some topic that when he increased polling interval to 45000 (ticks or somthng) the smoothness raised and G3 stopped lagging at all
And third reason is too bad design of CPU cooling made by LG. Here is the demonstration. CPU does not have proper thermal pad, so it spikes frequency and get too hot very fast, so it immediately lowers frequency down, and that is reason of stutters. HTC M8, Xperia Z2 and Galaxy S5 all have proper thermal cooling around SD801 so antutu doesn't suffer so much on them
