High DPC latency after new drivers

Hi everyone, recently upgraded drivers for

-Intel USB 3.0
-Intel LAN
-Realtek Audio




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.

Windows 7 x64 N (retail key, not OEM) with latest update + hide windows 10 telemetry

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