Only during gaming does the DPC latency appear significantly.
Only during gaming does the DPC latency appear significantly.
Approximately three days ago I experienced significant DPC latency issues. No major changes were made to the computer, just a sudden onset of problems. Monitoring tools like LatencyMon and certain drivers revealed affected processes: NDIS.sys, ACPI.sys, TCPIP.sys, CLASSPNP.sys, HDAudBus.sys, Wdf01000.sys, Dxgkrnl.sys. I've already tried reinstalling drivers (network, audio, GPU), performing a clean Windows install, and updating the BIOS. Despite these efforts, the latency spikes sharply after about an hour of use, causing noticeable noise and making playback impossible. All components appear up-to-date. If anyone has insights, please assist me.
