Those of you who are suffering stuttering, and have the updated microcode for spectre, I'd be interested to see how you fare if you roll back your BIOS. Intel have reported instability with the new microcode and I have reason to believe that it is effecting our frametimes. https://newsroom.intel.com/wp-content/uploads/sites/11/2018/01/microcode-update-guidance.pdf If you are able to test with and without the microcode update, and present frametime graphs of comparable situations, I'd really like to see it. The power monitoring issue still remains even with the old microcode, though.... So leave that disabled.
