Just made that diagonal track placed not in same tick. Look like it help with "choppiness" but the slowdown exists.
Hope this smoth rail laying. So will wait some feedback.

Also have to say that item collector from DyTech can also create "choppiness" if a few of them placed near belt.
Modified version is here zip.
As it download from github it need exctract and copy "rail-layer" folder to mods folder.
ssilk, as soon someone confirmed that this helps I made pull request to github repository.
I already have change in my fork in this commit.
P.S.: finally figure out how hide url in link =)
