High DPC latency after new drivers

[AN94BALLER]

Hi everyone, recently upgraded drivers for

-Intel USB 3.0
-Intel LAN
-Realtek Audio

Download:Intel(R)_USB_3.0_eXtensible_Host_Controller_Driver_4.0.4.51.zip(idinf:317963)

Download:0005-Win7_Win8_Win81_Win10_R279.exe(idinf:286228)

DownloadROWinx64.exe(idinf:320484)


I have also matched the new driver setting with my old one, it's identical in terms of playback quality (44.1Khz, CD) and network setting is similar.

I would one at a time in between reboots to see which one causes it rollback them individually in device manger if you can.

It should only let you roll back to the last one in this screen. You could also try system restore.
