Sorry if this is redundant, but I've searched the forum and read other posts and can't resolve.
 
I'm experiencing excessive delay trying to record electric guitar.  I've cranked the ASIO buffer down to "2 ms" using my driver interface (Scarlett MixControl); in Cakewalk this reports a roundtrip latency of 6.2 ms.  I'm fine with just the guitar, no audible latency - but then I only hear the raw guitar signal with no effects, which makes it hard for me to have a good take with feeling in it.  If I turn on the Input Echo button so I get the Fx, there's a huge delay.  (I use Guitar Rig, but even with GR off and no Fx, it's still a huge delay with Input Echo.)  And I have no other Synths, no other Fx right now -I'm at the start of a new project with everything clean.  If I use the "Zero-Latency" on my Interface, that's also just the dry guitar signal with no Fx.
 
Is there a way around this, so I can actually hear some Fx on the performance to get the feel?  Or is it just my computer is inadequate?  (You can see my equipment in the signature.  I've removed all other audio drivers.)

Zero latency monitoring is something you can get with an interface like the UR44 which offers some decent amp sims. Before I got the UR44 it would involve monitoring either a direct out from the amp or a Boss All-in-One pedal running through a mixer.

I would reinstall asio drivers! to begin with....remove, restart, install.....

Try bypassing all FX by pressing E.

Bypassing Fx doesn't really solve my problem - I am actually wanting to have some degree of Fx to get a feel of the sound while playing.  Plus it doesn't change the delay with Input Echo.  I'm actually OK with just the dry signal, since I can get zero latency with direct monitoring through my interface or with the dry signal through Sonar.
 
I can stick with a direct output from my a guitar amp (having the dry guitar signal to run through Guitar Rig, but getting an overall feel audibly from the amp), I was just hoping for a way to do it all internally in Sonar.

Bypass FX that are on the Main outs.  Make sure you don't have any active high latency plugins like Slate Virtual Tape Machine in your guitar path.

Use an amp?

Anyone still doing that these days ???? ;-)

Save your guitar rig tone as a preset and try to play it through the standalone version of guitar rig ...
 

• if you have noticable latency there in GR5 that distracts you, you need to adjust the preset (change some FX in the chain) ...

• if you don't have noticable latency, then some other FX (or several) inside Sonar cause the latency ... disable all and just use the most important ones (switch them on one by one to see which is causing it)

You should be getting very little discernable latency if guitar rig is the only fx enabled.
If there are other fx or midi instruments try freezing them/bouncing them to track.
You can also try clicking the 'pdc' button which will disable plugin delay compensation whilst you record your part
