Latency Checker
Latency Checker doesn't work on anything past Windows 7, LatencyMon is recommended.
LatencyMon
This is a GTX 1080 @ load.
This is how it should look like:
For reference, here's a healthy 750Ti under max load with LatencyMon:
"Current measured interrupt to process latency" and "Highest Reported DPC Routine Execution Time" are the most important value with LatencyMon (LatencyMon is compatible with Windows 8/8.1/10)
"Current measured interrupt to process latency" is your current DPC latency in real time, "Highest Reported DPC Routine Execution Time" are your DPC spikes.
LatencyMon is intended to troubleshoot audio issues, such as crackling and dropping audio streams. Not GPU "stutter", but ideally your DPC readings should be as low as possible, under gaming loads anything below 50us is PERFECT, below 100us is AWESOME, below 200us is OK, above 200us is not OK, anything close and above 500us is a serious problem.
Your idle readings must stay below 20us at all times, ideally you should have less than 5us for "Current measured interrupt to process latency", you can basically ignore the Pagefault readings as these are just the amount of commands loading the RAM from your storage and OS drives.
Your load readingsmust stay below 50us at all times, ideally you should have less than 30us for "Current measured interrupt to process latency".
If your nvlddmkm.sys causes the high latency it means the Nvidia driver is the main source of DPC latency in your system, post in the Nvidia thread so they can find a solution, coming from a R9 290X to a GTX 1070 G1 I hope Nvidia fix this soon or I'll probably regret going green.

UPDATE 1:
A fix seems to be in the works.
Here's the knowledgeable user Cookieboyeli with great insight on what your target DPC latency should be and why.
Cookieboyeli's useful post.
UPDATE 2:
NVIDIA Display Driver Feedback is a survey born from this issue, I urge anyone with Pascal GPUs to check Cookieboyeli's post before using LatencyMon and then filling Nvidia's survey if you encounter any problems, it should help tremendously on the process of fixing this elusive bug which as many have said has been (to a lesser extent compared to Pascal) affecting several generations of Nvidia cards.
NVIDIA DISPLAY DRIVER FEEDBACK.
