Hello
I would like to choose best performance and kick off unnecessary apps and perform tweaks
to have best available DPC latency on my computer in order to make music production.
I have applied BootSpeed tweaks, also affinity for my NVidia GPU, uninstall unneeded apps, disable my intel speedstep, choose power plan to make high performance (disable sleeping for devices), I have updated win11, I disabled unused features such as bluetooth, fax and unneeded devices, disabled HPET etc., hw connected as possible - ports verified, more in detail, sfc and dism- processed, ok results, I provide also those steps and my configuration for your opinion on this in order to recommend me additional steps, or what to do more for best possible result in my configuration
I understand, that its a lot of information at once, I just spent time to get this information and collect and I can send my current configuration in order too.

In general, I have question related to DPC latency once I am able to go around 100 microsecs., but not less - the way is, that I have 20-50 microsecs and after some time I go to around 100 (highest dpc exec.time)
I also monitored performance and got ntoskrnl and dxgkrnl/nvlddmkm and ndis with a bit higher numbers caused this.
Focused on drivers, updated and measured, not sure, how to process with better configuration still - I have disabled sleep modes and disable ipv6 etc.
I use 128/256 samples with 24bit/48000Hz for my audio configuration, the same in audio card, same in my Cubase projects and I disabled internal audio card onboarded.

Any your suggestions, where to focus, those are very appreciated to get best performance possibilities for my music production mode.

Thank you in advance
Kind Regards,
Miroslav
