hi everyone, I 'm having trouble with latency, i have attached 2 things from a test i did. i have no idea what any of this means. what I've done so far is all the optimizing that i know how to do. i have a song that is not very complicated, . however, even when i disable the plugins i'm still out of time. can anyone make sense with this please./>" />

Most important info is what interface are you using and what driver mode and buffer settings. Buffer setting are where you adjust for latency, your system should be able to go with lower settings but that also depends on the brand of interface.

^^^^ info on the above would be helpful. Additionally, plugins with look ahead also introduce latency. For playback only, these will not be problematic, but if tracking they will be noticeable. If you hit "E" (global FX bypass) does the latency go away? If so, it is a plugin.

You don't really mention what your latency problem is. Are you unable to get the latency down where you want it without pop's and crackles?  What audio interface are you using?  from the LatencyMon picture it looks like you have the on-board sound card enabled. Is this what you are using as your audio interface?
 
You can try to disable Wi-fi, virus scanners, and windows indexing services (used for searching your hard drive) and see if they make any difference.

Try going into Device Manager and disabling any HDMI audio things that show there. Often gpu drivers come with them and they get loaded by Windows even is the monitor attached to the gpu hasn't any speakers and isn't being used for audio. Unless you need to use them for a specific reason of course. Craig Anderton posted a while back that he'd found this fixed a latency issue he had and latencymon appears to be pointing the finger at the HDMI audio subsystem.

Don't uninstall them though, just disable. If uninstalled Windows will simply re-install the drovers the next time it boots.

Your DPC latency actually doesn't look that bad. The longest is 1 millisecond. That's not particularly great, but it's not bad, either, and shouldn't be a problem.
 
Could you elaborate on what you mean, exactly, by "problem with latency"? Are you playing virtual instruments in real time and are unable to lower your buffers enough for that? Do you perhaps have some high-latency plugins that shouldn't be in there while you're still in the tracking phase?

I see LP-64 Multiband in one of the FX bins. That's going to induce significant Plugin Delay Compensation in the project. You can enable 'PDC' [override] button the Mix module in the Control Bar to override PDC on input-monitored tracks if the PDC-inducing plugin isn't on the track being monitored.
 
Ideally you want to avoid using Linear Phase and other 'Mastering' type plugins that require PDC until you're done tracking.
 
Deferred Procedure Call (DPC) latency (what LatencyMon measures) is not to be confused with Plugin Delay Compensation (PDC) or other sources of audio latency. DPC latency is a measure of how quickly the PC can respond to a request to render and pass a buffer of audio to the interface. Audio latency (including PDC) determines how much time elapses between a real-time action like picking a guitar string, hitting a key on a MIDI keyboard or changing a control setting in the DAW, and hearing the result.
 
DPC latency limits how low your audio buffer latency can be set, but if it's too high for a given buffer size, the symptoms will be pops/crackles/dropouts due to dropped buffers, not increased audio latency.

thanks so much to you all, I 'm going to try and answer your questions from the top down and will attach screenshots.
1.CACTUS MUSIC, look at screenshot, these settings i changed last night from the default settings and i don't know yet if it worked.
2.mettelu, yes, i realize that, however, there are not many plugins and/or tracks.
3.reginaldStjo the problem is, when i record a new track i'm a little behind, sounds like a quick delay.  not using the crappy soundcard that's in the computer, however, i see sometimes if i try and use ASIO4ALL i can't turn off the internal soundcard. but i really like using the quad-capture, i only have ASIO4ALL in there for something else.
4.reginaldStjo i don't know what HDMI is.
5. bitflipper i'm not quite clear on your answer. however, when I 'm recording/tracking i'm coming out of my amp into quad-capture.
6.brundlefly. again, i'm not sure what you mean. however, i do (i think) understand that some plugins will need more power than others so they should be used only after tracking.

again, thanks so much for taking the time with this. i am most grateful.

Hi. My advise would be to uninstall ASIO4ALL (it causes issues in some situations), reboot and install the ASIO drivers that comes with your Quad Capture. 
When recording, press "E" to bypass all plugins. It will help with latency.
The LP-64 MB is a mastering plugin that induces latency, and is best used when mixing / mastering, when latency is of no concern.
All the best.
