Btw this doesn't seem to be universal problem with FF ProQ2 and Sonar because the combination works fine for me.

Your video shows very high disk I/O. That could be a factor. Try freezing the source track (but not the fx bin) to reduce disk activity, and see if that changes anything.

yeah its disk space, its in red, ill free some space... i dont think its the problem tho but should help.
sanderxpander, PDC is off, i didnt know about that one. is it good?
i think the main problem is, i have too many plugins, somes make the audio laggy. like u saw on the video, when i press play, its long to start, and on the ffQ2 we also see it.

Give us some idea of what you're dealing with here.
 
System spec would be useful, as well as your hard disc setup - how many drives, size, application etc.

dunno if it work, i just tried to add it like u in my "signature". not sure if it work, i see "signature" and "comment".
Sonar Platinum 21.13 x64
I5 2320, 8Go ram, Win7 pro 64, 5 x 1Tb Internal Sata HDD 7200rpm mbr, internal m-audio delta audiophile 2496

test, doesnt work....
 
edit: oh yeahh! 

my disk load is 18% max only. no big deal

PDC bypasses plugin latency compensation for any track that has input echo on. It's mainly useful if you're recording in a project that already has a bunch of high latency plugins. It can make tracks of recorded material sound out of sync if you forget that it's on and you enable echo. If that doesn't solve your issue just leave it off and forget about it.

While it is true that all plugins add "some" latency, for many/most plugins this is completely negligible and you would never notice. Specific types of plugins add significant latency, it would be worth figuring out if any of these are making things go out of sync:
Limiters or transient designers (since they tend to use "look-ahead" techniques)
Linear phase anything (e.g. ProQ2 in linear phase mode, or ProMB in linear phase mode).
Convolution based reverbs like Perfect Space, IR-1 or Altiverb.
Specific other plugins with look-ahead, like possibly some noise canceling plugs.

You could delete these from your project as a test and see if the situation improves. To be honest though, I'd be surprised. Plugin latency compensation shouldn't have issues like this. I've never noticed any with ProQ2 although I don't always need to automate it. Is it at all possible that it's doing it at the right time in the audio but the image just doesn't line up? That could be a result of latency compensation.
