Like I said , wdf01000.sys only had high dpc when I had BOTH- ESET and MBAM (MalwareBytes Antispyware protection) I don't have wdf01000.sys dpc at all now. I only have DPC jump when I open Chrome or using chrome when the GPU Clock changes, just happens straight away with chrome. but if I disable Eset RealTime protection and HIPS I don't have this jump either. it just LOW DPC All the time . If you have 980 Ti then it could be different story for you.... this issue is 10xx specific series . So what ever happens to you would be different for me. I didn't have any issue with 970 for example..
