I've been trying to find a reason of why my new pc got issues with latency and one of the culprit drivers was ACPI.sys
Apparently whenever AIDA64 started worked ACPI.sys would have the second highest DPC/ISR timings as well as execution time over 1ms
Switching off kernel driver in settings fixed the issue after restarting AIDA but unfortunately it would also make me lose GPU temps and loads.
I've been wondering whether this is a normal behavior or whether it can be somehow avoided?
Also i've been wondering whether AIDA64 uses driver called wdf01000.sys which is causing delays over 500ms as well as huge lag spikes and sound stuttering when used in combination with LCDHost and G19s keyboard?
When Aida64 is running with sensor panel in the background, there is random audio drops when I play any youtube video. It does not seems to affect the video, only the audio break up for a split second. Once the I exit aida64 in the notification area, the intermittent audio drop stop occurring. There is a particular order that it happens, Aida64 MUST start first and load youtube video next will cause it to happen but not vice versa. Sometimes playing xbox music in the background could trigger this audio drop, but it occur more often in youtube.

The motherboard support DTS output, and the optical cable is connected to a AV receiver. The receiver decodes DTS and the logo disappears whenever the audio dropout happens, so it is very annoying and obvious. This has never happen before, even when I play intensive games, the audio has never drop out. I kind of suspect it is due to the polling of the sensors and it is affecting the latency or DPC that could cause this.
