I've similar problem. Many years I used MC with madvr (d3d 11 playback without lots of postpocessing and scaling) on i5-8400 with GTX 1080. Everything was super smooth on my FullHD Sony projector on 24fps. Now I've changed card to RTX 3080, install latest drivers. Rest of components or settings in programs stay the same. Games, stress test - everything is fine. But there is strange playback issue in movies. Like dropped or freezing frames in every second. But Ctrl+J info says there is no dropped or delayed frames. I think on PJ it's more present than on 4k monitor. GPU load is 15-20% max so it's not a problem.
But changing renderer to JRVR makes playback supersmooth. I think in terms of quality it's little worse from madvr but for now it's only solution to my problem.
PPMPPM:
I forget to add that playing in another program like MPC-HC with madvr produce that same effect - jerky playback. So problem is not inside MC.

This sounds like what I had when I initially got the C1.
I had a piece of software monitoring my GPU, something called Telegraf that I use with InfluxDB for time-series monitoring across all of my hardware. Every time it would poll Nvidia SMI for the GPU stats, there was this tiny video hitch, like visually but nothing in MadVR to indicate it.
I only even thought about it because I realized that the 'interval' for these hitches happened to be the exact interval that the monitoring software uses. I wouldn't be surprised if this was long since fixed, or unique to me BUT, it's something to consider. Try seeing if you have monitoring software running.
EDIT for clarity: When this happened, the issue with Nvidia-smi, it wasn't happening on a 23/24/60hz 1080p display, only the C1 at 4K 120hz, further adding to the confusion. Seriously, it was incredibly unlikely that I was able to trace this problem to a specific piece of software, so you may have your work cut out for you and finding what's causing your problem.
