I having Dell G5 with I5 8300G,16GB RAM and GTX 1060 max q overclocked to 1800mhz. The problem is that even with the latest BIOS update the DPC latency on latcncymon is showing red bars. Does this affect gaming FPS performance?

high dpc is driver related
anyway, see task manager, if u see high cpu usage on system interrupts, if its high, then it can affect your ingame fps

The cause of DPC latency is from ACPI.sys. but i cannot exactly figure out how much CPU usage is increased but one thing is that when every the wifi card usage goes up the CPU usage also goes up and the DPC latency is increased.

Here is execution stats

Index Group, # Interrupt cycle time (s) ISR count DPC count Highest ISR execution (ms) Highest DPC execution (ms) Driver with highest execution

high dpc from acpi.sys isnt anything unusual on notebooks
compare intel chipset drivers vs OEM provided drivers, if u get any better result
see your power profile, try high performance mode
try windows clean boot (without preinstalled bloatware/monitoring tools provided by your OEM)
https://support.microsoft.com/en-us/help/929135/how-to-perform-a-clean-boot-in-windows
which Intel driver should i try instead of OEM drive, apart from BIOS and Audio i did not download anything from Dell, its windows updates which automatically installs the drivers. The driver you are talking about seems to be intel dynamic platform and thermal management framework
