Recognition data should be the default mode. To double check and make sure that is the case, go to wacom property and double click on the tablet icon.
I read a post from CGTalk somewhere that standard mode has 100khz, and Recognition Data has 200 Khz. And with lower khz, the wacom picks up a lot less handshakes, thus gives out a smoother result. I gave it a try and switched to standard mode, and it does seem to have improved a bit. But the brushes become very unstable, and it is very frustrating.
