Process Lasso made a substantial difference on Win 10 @ 64 samples

1

In case this helps someone else…
I finally got around to installing Lasso on my Primary and Backup rigs. Even though I’d fully optimized using Brad’s and other guides when I got new gear about a year os so ago, there were still a couple things that had reverted. I used Claude AI for all the Lasso settings and it definitely runs smoother, faster state changes, no crashes even when doing extensive editing (which i would get on heavy songs). I also made some tweaks to:

  • PCI Express → Link State Power Management → Off (don’t know why that was on)
  • I found a couple network adaptors that still had “allow computer to turn off power” checked… again odd, thought I’d had that set.
  • Uncheck PCIe ASPM Support in BIOS.

I’m not a computer expert like many here are, but my guess is that some of the Windows updates changed some settings. And my “non-lasso” tweaks may not be making a difference, I don’t know… but all I know is it’s running better than it has in a while, and I have some fairly heavy cpu songs. Thanks to all who pointed out Lasso!

Hi,

When Windows does a major update, it can sometimes revert power settings on PCI and UB, so always worth checking periodically.

I have used Process Lasso for quite while, and find it really useful. I am curious about how you have used Claude AI to define the settings? Can you explain?

I just queried best settings for Lasso using Cantabile and gave it my PC specs, CPU, Win 10, etc. I switched from Chat GPT to Claude recently, Claude seems much better, few mistakes.

What might those Process Lasso settings be? I remember all I did was install Process Lasso and 1) Change Cantabile Process Priority to HIGH, and 2) Change Power Profile to “Bitsum Highest Performance.”

Those are the most important ones but here’s the whole list, which has a few that aren’t Lasso-specific… most are also in typical Optimization guides, but I don’t recall the BIOS ASPM Support part. OTOH I don’t know if that was really important or not… only that I’m running a lot cleaner now, even though I’d Optimized or checked it 2-3 times per year.

My limited understanding of the CPU sets is that’s pretty important too, since it directs the processing to the physical cores.

Process Lasso

  1. Install Process Lasso, let it run as a service
  2. Right-click Cantabile.exe → Performance Mode → Always
  3. When prompted about Efficiency Mode → click Yes to create the OFF rule
  4. Right-click Cantabile → CPU Sets → Always → check 0–7 only, uncheck 8–15
  5. Right-click Cantabile → Priority Class → High → Always
  6. Right-click Cantabile → Exclude from ProBalance
  7. Leave I/O Priority, GPU Priority, and Memory Priority all at Normal

Here are the Windows-level tweaks, step by step:

Power Plan

Win + R → powercfg.cpl → Enter → Change plan settings → Change advanced power settings

  • PCI Express → Link State Power Management → Off (both)
  • USB Settings → USB Selective Suspend → Off
  • Wireless Adapter Settings → Power Saving Mode → Maximum Performance (both)

Click Apply → OK

Device Manager

Win + X → Device Manager

  • Network Adapters → right-click each one → Properties → Power Management → uncheck “Allow the computer to turn this device off to save power”
  • System Devices → find Intel Thunderbolt Controller → Properties → Power Management → uncheck same option
  • If you disable WiFi during gigs: right-click the WiFi adapter → Disable

BIOS – just do first one here:

  • Bios> “Power, performance and cooling tab>Secondary power: Uncheck PCIe ASPM Support (PCIe ASPM → Disabled**)**
  • Thunderbolt Security → No Security or Always Authorized- (I didn’t have this option in my BIOS)
  • **If still getting buffer spikes at 64 samples: disable CPU C-states as last resort (I didn’t have this issue).
    Hope that helps,

Thanks! I’ll follow this checklist and see what happens.

BTW The CPU sets to be checked or unchecked related to my specific processor… You might want to double check on your CPU and physical cores count

Process Lasso was setup as listed. Note that my Cantabile Laptop is Win10 and Efficiency Mode appears to have been introduced in Win11 (Menu is grayed out). CPU is i7-8750H which shows 12 cores in Process Lasso. Kept 0-7 checked for affinity and see what happens. We’ll see…
