I do get frametime spikes as frequently as I experience microstutter though, although to be quite truthful here I am ignorant to how high a frametime spike needs to be so that its perceived as microstutter while gaming.
Are you overclocking your card?
I have found that my 1080 will fluctuate between 1600mhz and as high as 1850mhz at stock speeds, which in some games can create rather large frame spikes.
I have been using EVGA precision OC tool in manual mode to control the speed curve. I have found that leaving everything at stock, and then setting you desired overclock at about 1.00v in a flat line both gives you good performance, levels out the boost clock to a flat line eliminating frame rate variance, and for myself has made it much easier to test my graphics card for stability.
This will only smooth things out if you are playing at or below your montors refresh rate.
