Question / Help Understanding FPS/Hz relationship. Video looks choppy on recording.

Hello;

I am just getting into recording some games locally with OBS. No matter what I do, the videos always look... choppy, like the are dropping frames, even thought the log says that no frames (or <1%) were dropped.

PC Specs:
CPU.- Ryzen 3900X
GPU.- 1080 Ti (a little overclocked, with an Arctic Cooler Accelero Xtreme IV)
RAM.- 32GB DDR4 @ 3000
SSD.- Intel 750 1.2TB NVMe (this is not my OS drive, just the record-to drive)

My display is an ASUS PG348Q, which is 100 Hz and has a G-SYNC module. Oh, and it is ultrawide, doing 3440x1440. I followed some of EposVox advice when configuring OBS. Nevertheless, I set my canvas and output to 2560x1440 at 60 fps.

So far, my theory is that the "choppyness" is a result of recording at 60 fps while, say, Borderlands 3, is doing 80+ fps. If I cap the game at 60 fps, the "choppyness" improves, but doesn't disappear completely. Same thing happens in Doom Eternal.

I have options, I guess. And I wonder how you guys do it. Do you cap the game's fps using Nvidia's control panel to 60? Or set the display to 60 Hz since G-SYNC will "cap" it? All of the above?

Another question I have has to do with G-SYNC. I usually just turn it on on the control panel; but I see some people mention that I should set V-Sync on in the control panel (and off in game). Is that correct?

I attached the last two log files that have been created.

Thanks for your guidance.

Even with no frame drops there will be noticeable stutter from pulling down from a high frame rate source to a lower one if you don't use even multiples.

So from 100hz you can drop to 50, but dropping to 60 or 30 will have some (minimal) stutter. 60 or 120 would be better.
