Meh cant please em all.UI lag? How about getting all the functions of the phone stable first? Turn off animations in spare parts or set them to fast. LG has screwy adds to the AOSP coding to deal with..i.e. MMS. Even G2X (Cyanogen himself) /2X devs have had fun fixing the LG screw ups. aosp (OV dev) is only 1 guy...and unfortunately has a life
So patience will have to be a virtue until he fixes or LG drops source for GB/updated libs
If your experiencing UI lag I highly suggest backing up and wiping everything and reinstalling.
Then One by one reinstall each app and play with the phone a bit between each install.
I would almost be willing to bet you have a app that is taking over the phone.
Initially I had horrible experience with asop and some functions.
Then I realized it was a app I had installed. Dont remember which one now.
But it only gave me problems with the asop rom. Zefie's rom was fine.
