Well, i'll chime in.
I believe it starts by knowing the system being used, and devices Put into it...from Bios settings, to windows and drivers....it all helps to know what you want to do with the machine, and what is not necessary for that , that may be installed as a device, with driver, or bloat ware preinstalled...hard drives, efficient power supply and surge protection.
And software that may interfere with the Process of X3 Studio... Like problematic software, virus programs, firewalls (if causing issues), and or networking devices, internet/ or any "conflicting devices, or if having issues with other audio devices being used in Sonar" and physical IRQ sharing be checked out, and reduced...etc, with audio devices...Yes even ATI video cards can cause issues, with the HD audio being used, if so, with other audio onboard the MB, or other add on audio cards...So dependant on what and how you setup your system, can be the be all or end all.....
So, lots to think about....Not much in the description as to what you are using as a audio device, or hard drives, or add ons in your posting , so excuse my vague widely scoped replies that apply to the base of all systems.
The more Memory you have the more reliable I find PC systems to be..I would definitely go 16gb ram.
The cpu seems to be the work horse in doing the record and playback , use of Plugins, and utilizing the devices, and running services for the OS...ect with sonar.., and running the engine of that.
So a wise choice is being over looked, or over ruled....By not updating the system cpu...things will slow down when bogged down with work loads...but it should work ok if all things are made easier for that to be done, without interruption by other tasks or services running in the background.
Knowledge of IRQ usage.
Some say it is not important anymore to worry about this IRQ usage, as Windows has virtual ones....But the physical truth is there are only so many of them on the motherboard , that page the cpu to be used...too many shared IRQs will cause hick ups in the processing of..X Y Z....and use of devices, as they get interference from this sort of paging, and calling services to use those devices or run them in background.
If something is asked to do a task, does not get done in time,...or is held until free use can be made of the cpu...it could cause glitches in the work load being asked to perform...if it does not cause too much issue, it could result in a glitch in audio.
Or too much could cause the system to hang...and become none responsive...and or crash, if a conflicting event occurs.
So that would be a start to understand.
Tweaking the services, like automatic updates...Using: "msconfig" and hiding all MS services first, and turning off third party auto updates, and sorting what gets loaded on boot up...could help stop unwanted actions being done by third party apps running on the OS, behind the sonar software.
And yes I turn off windows updates, and do it manually .
Turning off redundant devices in control panel/ "system"/ "devices manager"....before using Sonar.
One can go a step beyond by defeating some things (devices not being or going to be used) in Bios.
So knowing the system you have is most important, and what you want to do with it.
And find the best setup to do that with....that system.
Write down your changes....Keep a log.
That is where I would start.
Oh yah, the usual, turn off the power saving features in control panel/power options,keep hard drive always on, and screen savers, and such off,...and any high performance tweaks for video " Best performance settings?"...might help to make it plain jane with no acceleration or just a few...could help gain a more robust and pleasant system performance with Sonar....but you have to test that out one step at a time....
Best of luck.
I tried this guy's tweaks out on win 98/xp/win7...:
http://www.blackviper.com/service-configurations/black-vipers-windows-8-1-service-configurations/ But a lot of knowledge as to what you want to do...and when making tweaks always write them down, so you can restore things before updating the os.
other wise you will get page errors and corrupt updates.
