Realtek new driver in MultiBeast 6.3.1 RTL8111 v1.2.0 : what's new and how to install over RTL81xx v

[MilesTEG]

Hello,
I have installed Mavericks with MultiBeast 6.2.1 with Realtek driver RealtekRTL81xx v0.0.90.
Since the new version of MultiBeast 6.3.1 released, I wonder about putting the new RealtekRTL8111 v1.2.0 driver.
But what give the new driver compared to the old one ?

Second question : I try to install the new one with the lasted MultiBeast, but it doesn't seems to be installed as I found only the RealtekRTL81xx.kext in /System/Library/Extensions/ .
How can I uninstall the old one in order to install the new one ?

Thank you very much

Miles

I am not sure of the difference but using the 1.2.0 drivers caused me to have random network drop outs when I tried to send a lot of data over the line at one time. I switched back to the 0.0.90 driver and the problems went away.

I had also some disconnection...
I try to install the 1.2.2-dev3 version (found on insanleymac), and it appears to be stable.
