I need help understanding and hopefully improving the performance of my DAW PC. While mixing, I experience more or less constant dropouts though the dropouts aren't so bad as to prevent me from mixing and making adjustments. At no point do, either the Cakewalk Performance Monitor or the Windows Resource Monitor show any CPU thread exceeding 25%. Why isn't my CPU working harder? What can I do to improve performance.
I've run through Sweetwater's DPC Latency recommendations and results look good. (See 4 attached results screenshots)
I've run through Sweetwater's DAW PC Optimazation recommendations and provided more details about my DAW PC in the attached PDF summary.
I have Use Multiprocessor Engine and Plug-in Load Balancing ticked. (See attached Audio Driver Settings screenshot)
My Focusrite 8i18 (original USB 2.0 version) audio interface adjust the Mixing Latency Buffer Size based on a user selected latency in ms. It's usually set to between 15 ms and the maximum of 20 ms for mixing. A setting of 20 ms sets the Mixing Latency Buffer Size to 883 samples. (See Audio Driver Settings screenshot attached. Also note ASIO reported latency values which far exceed the 883 samples.
During playback, all threads hover around the bottom on the Performance module. No threads ever goes above 25% but there's a lot of audible popping and cracking and I don't know why. I've only recently started using the iZotope Production Suite which I really like and I suspect that products represent a significant CPU load, but the CPU doesn't seem to notice them. Any ideas why this is happening or what I can do about it?
Mixing projects I'm working on now tend to have 8-12 audio tracks, 8-10 aux tracks and 3 buses. Sample rate is 44.1 or 48 kbps and recording bit depth is 24 bits.
I usually record no more that 12 audio tracks at a time with no processing and don't incur any problems.
