DPC Latency problems

Please check my guide on how you can run Cubase with permanent CPU affinity on only P-Cores: You dont need to disable E-cores in BIOS.

Some plugins use cpu differently than others, like ex. Acustica Audio. Audio performanace 90%. but cpu cores about 30% sometimes its normal. Check your DPC latency.
