I do see a decent improvement with the latest version. However, I find some glitches in the output video when using certain LUTs. Attached is an example of a cube LUT that works, and a .dat LUT that produces colorful glitches in certain areas of the frame.
I am using a sample clip from ftp://ALEXA@ftp-footage.arri.de/01_DNxHD_16-9_1920x1080/23.976fps/J001C001_140110_R6MS.mxf
FTP password is samplefootage.

Dat LUT: https://dl.dropboxusercontent.com/u/33335399/Arri_LogCto709.dat
