Unworkable latency/CPU problems after upgrading to a BETTER laptop?!

Sorry for the repost, nobody really answered last time, trying to work out how to get some images up so people can help better?


I'm running a Lenovo gaming laptop with i7 quad core, 12gb dd3 ram, 1tb with 600gb free.


I'm having two problems, using asio4all v2.12 with a Alesis io2 express interface, even down at 64 sample buffer size I'm getting latency that renders recording impossible. It claims I have 5.44ms Input latency, and 3.46ms output latency, thats not the case, get closer to about a quarter of a seconds delay no matter what settings I use, changing the buffer size changes Ableton's readings for Input/Output latency, but makes no actual change to the audio coming in through my interface. Last time somebody suggested using the driver for my interface, but its an Io2 express, meant to work without drivers and just through asio4all.


My other problem is that Ableton keeps running out of CPU. I wanted to upload a screenshot showing Ableton running at 92% with only a few midi tracks with abletons sampler and a few audio files, but Task Manager is open and says the computers CPU is only 13% in use, and only 3/4gb of the 12 available of RAM are being used. It seems Ableton isn't making full use of the resources available to it. I've enabled multi-core processor support in settings aswell. 


My copy of Ableton 9 ran ten times smoother on my old macbook which had half the power. I know the latency isn't a problem with my actual interface as it still works perfectly fine on my housemates mac.

    Remove all unneeded processes, like Anti-virus, Adobe Updater, Lenovo Bloatware, etc... anything that is not critical, remove it. Check system tray or taskmgr.exe.

    Then increase your swap file size to 24GB  

    Computer Props>Advanced>Performance>Swap File>Custom Size.

    Also set in the same area, set computer to performance mode.

    Set your Defrag to run, I do mine daily. Also  you can use a utility like ccleaner to clean the registry and hijackthis to remove startup hooks.

    I had a USB M-Audio M-Track and it had bad latency. I replaced it with a UA Apollo Quad and added a Texas Instruments Fireware 800 PCI-Express card to my PC. No more problems.

    Hi there, 

    The performance hog in this case might actually be the interface. Your computer is more than powerful enough for Live, but the audio interface might not be able to run Live in such low latency settings. 

    The further you decrease the buffer size, the more CPU resources will be needed by Live, which could also explain the CPU spikes you are seeing. 

    There are a few articles which can help finding the right latency / performance settings for your machine, we recommend going through them step by step. 



    Just on a side note, the CPU meter in Live is not always accurate, the following article explains why this is: 


    Hope this helps,

    FIRST THINGS FIRST! The DPC latency and drivers.

    Check your DPC latency,  if you have a new powerful laptop and you are having performance issue, it may well be that a bad driver in your system is eating all the resources.


    Download a DPC latency checker tool (http://www.thesycon.de/deu/latency_check.shtml)

    in a working system your latencies should be below 100uSec, if you have bad driver the DPC latency times can be as high as 500-1000uSec.


    If you are having high DPC latencies, download this tool: http://www.resplendence.com/latencymon


    It is a bit more advanced but still rather straightforward to use. Let the Latency Monitor run for a while and check the list which driver reserve most CPU time (usually WiFi or bad GPU driver). For example it you have a network adapter driver uses a lot of CPU time, you can try to disable it from the computer management and see if it helps the audio performance. If it does help, you should start looking for a new updated/alternative driver for that device (or leave it disabled if you don't need it)
