If anyone could provide me some insight on this issue, it'd be greatly appreciated. I've been searching for the past two weeks and have still yet to come up with an answer. T_T

System Model: MS-7693 (MSI 970A-G45)
Processor: AMD FX6300 6-core Processor Black Edition
Memory: 8GB RAM
DirectX Version: DirectX 11
GPU: HIS iPower IceQ X² Turbo Radeon R7 260X 1GB
Display Driver: AMD Radeon R7 200 Series

I've been having audio stutter and extremely high latency recently and I used DPC Latency to narrow it down to the AMD display driver. I've reinstalled every display driver from the current one down to 14.1 from the AMD website and used DDU to uninstall the drivers. No matter what I did, the high latency would not go away. However, if I disable the display driver, then my computer will run with no latency issues, but then I won't have access to games and so on.

I used LatencyMon afterwards and it seems that ATAport.sys, dxgkrnl.sys and USBPORT.sys are the culprits. I called AMD and Microsoft to see if they knew anything about it, and they were completely clueless.

Anyone have any input on this?

Thanks in advance
