Hi All, afraid I need some technical help.
I (unfortunately) just bought a dell laptop (Lattitude 5480) for use with cakewalk. On paper, this thing is a beast : i7-7820HQ processor, 16 Gb Ram, Pcie(4x) SSD. It's a great laptop, very fast and capable, but turns out it's completely unusable with any audio program due to DPC latency
LatencyMon shows the culprit as ACPI.sys - I'm getting latency readings of over 2500uS, which results in lots of audible clicks and pops with reasonable ASIO buffers (256)
I've done all the usual: disabled c states, turned off speed-step and turbo-boost in Bios; Set all power plan settings to max performance; Disabled network, on board audio, camera, microphone array etc in device manager - but nothing works. The only thing I can think of now is to try and set processor affinity so cakewalk only runs on cores 2,3 & 4 - the DPC spikes seem only to occur on core 1. Is this possible, and does anyone have any experience or knowledge of doing this? I did attempt creating a shortcut that set the processor affinity using this article :https://www.eightforums.com/threads/cpu-affinity-shortcut-for-a-program-create-in-windows.40339/ but without much success.
Is it possible to restrict Cakewalk to only use certain cores, and is it a viable technique to get around DPC Latency issues?
Any advice gratefully received, as this is starting to look like an expensive mistake...
