I own a Dell G5 featuring an Intel Core i5-8300G, 16GB of RAM, and a GTX 1060 graphics card that’s been overclocked to 1800MHz. However, despite utilizing the most recent BIOS update, the DPC latency in latcncymon is consistently displaying red indicators. Does this issue impact my gaming frame rates?

The issue is likely due to a problem with your graphics drivers. Check Task Manager; if you observe elevated CPU usage associated with system interrupts, this could negatively impact your in-game frame rate.

The root of DPC delays stems from ACPI.sys, though I haven't precisely determined the extent of additional CPU load. However, a correlation exists: whenever wireless card activity increases, so too does CPU usage and DPC latency rises.

Below are performance measurements:

Index Group, # Interrupt duration (s) ISR occurrences DPC occurrences Maximum ISR execution time (ms) Maximum DPC execution time (ms) Driver generating the most execution

Unexpected high DPI readings originating from acpi.sys are generally not problematic on laptops.

Evaluate the differences between Intel chipset drivers and those supplied by manufacturers when they are available – you may observe improved performance.

Examine your power settings and experiment with the “high performance” mode.

Attempt a clean boot configuration—remove any preinstalled software or monitoring utilities bundled by your computer’s original manufacturer.

Instead of the original driver provided by Dell, which is largely due to Windows updates, what Intel driver would you recommend? I haven’t installed anything beyond BIOS and audio – all my drivers have come through Windows updates. The driver you mentioned appears to be the Intel Dynamic Platform and Thermal Management Framework.
