It wasn't there during the last session. My setting for the 2i2  is 3 ms.

Have you applied any VSTs to any of your tracks since the last session at all?
 
The other day I'd done a mix I was happy with overall, but I wanted to have another attempt at doing the vocals.  I found a hideous amount of latency which went away when I got rid of the VSTs off the tracks.
 
A bit of an irritation, but there you go.

Does that mean all of the tones will be clean?

If you remove the VSTs, yes it will simply be the clean audio tracks with no effects applied to them.  Each VST you apply increases the load on the CPU a little, and this in turn effects the latency.  At least, that is what I found with my (admittedly a bit crappy) laptop.

You just need to watch out for specific plugins that use a lookahead buffer that adds to latency and triggers Plugin Delay Compensation which delays everything else, including live inputs, to match the latency of the track/bus with the plugin. Common offenders are convolution reverbs. You can either disable/remove the plugin, or enable PDC Override in the Mix module which will let you hear input monitored tracks without latency, so long as the latency-inducing plugin isn't on that track or on a bus to which it's routed. It's best just to avoid PDC-inducing plugins during tracking.

Hey, Kevin. Welcome to the forum. and good on you for pointing the OP in roughly the right direction.  But see my previous post for clarification.  Most plugins do not add latency, and just adding CPU load won't increase latency, either. It's only plugins that use an internal lookahead buffer that have this effect.

And any roundtrip latency is likely to be microseconds for each plug-in unless you have a PC from the 90's.

Fair enough.  I just based the post on the my own experience when I found having a good number of VSTs loaded when trying to record an audio track induced latency, but disabling them all removed it.  I didn't realise there may be one specific plugin causing the problem, especially as there were no VSTs active on the track I was trying to record to.
 
And as I said, my computer isn't fantastic.  :)

That did it. I turned off Nectar 2 and all is well. It seems I really don't need S-Gear. FX chains are my friends. Thanks a bunch.
