Pfheonix

Found a link to relate the two technologies, but it's a year old. Updates are scarce, it doesn't seem that Razer Chroma works with Aura Sync.

I have, yes. I did go ahead and reset to defaults and then re-enable XMP, which I already had enabled. The reset returned it to a more normal frame timing, but I'm still wondering exactly what happened here, especially since undervolting reduced temperatures by about 10 degrees centigrade, and I definitely found that performance to feel identical until this issue cropped up.

I have recently built a Zen 2 based gaming system with an RTX 2080, a Ryzen R7 3800X, Gigabyte Aorus Elite Mobo, G.Skill 2x16GB 3800CL19 RAM, and various odds and ends in the storage department from various vendors. Referring to the attached screenshots, you will see, in the bottom left hand corner, the frame time graph. I realize it's annoying to read, GeForce Experience is currently experiencing issues in DX12 with screenshot colors being incorrect, this is not how it looks in game. The frame times appear to be CPU bound, but the regularity of the frame time jumps suggests something odd going on with either the clocks of my processor at a level that monitoring tools do not poll quickly enough to discover, or some other bottleneck that occurs with a high enough frequency to cause this sort of microstutter. Anyone know any potential causes? I have it undervolted for heat management, but performance has stayed relatively consistent until I turned on PBO, which I have since returned to the Auto setting it originally was set to, and moved my negative voltage offset from 152mv to 102mv. I am aware the undervolt past 100mV loses quite a bit of performance across a well-spread workload like CineBench, losing roughly 800-1000 points off of my prior score, but it was definitely capable of sustaining sub 9ms frametimes with little stutter. I don't understand why changing that back up to 100mV would cause this style of stutter, and so regularly. If you need any other information, feel free to let me know.
