The Framerate Judder/Frame Pacing (or call it what you will) is unreal...

Hello and good evening once again, dear and esteemed members of the OBS Community, the first post of this thread is going to be (probably) somewhat a long one and some hints of frustration might be present in it, forgive me if I describe something with improper terms or seem inconsistent with my explanations in general...

*SIGN* Alright, where to begin with and what questions to ask in proper sequence?

I should probably start by saying that I have made a similar thread on these very same forums a few years ago, (for a different game however) and there was a good deal of information provided to me by koala. I have also read similar threads and managed to glean bits of useful information written by BK-Morpheus and occasional posts written by other folks on different websites. The situation is basically as follows. I am making video footage for a popular game called Escape From Tarkov (I have attached one of the countless logs that i generated from all the tests) and even though there is no lag or dropped frames, the game footage is choppy and jittery to the point of really being noticable (I can link a video that I uploaded but do not know if this is permitted by the forum rules as an advertisement of some sort, so i will refrain myself from doing so). What really irks me is that (at-least in my understanding) EVERY possible step has been taken by me to optimize the game and the settings (and all the possible variables) that I could think of to have a smooth result as famous YouTube channels have, but to no avail...

EFT (As i am certain some of you might know) can be notoriously unstable sometimes, and occasional frame drops or stutters are fine, but in my situation it is different. I have tried solutions like capping the game to 120 frames, V-Sync being off and on, turning on G-Sync on the Monitor, etc etc, you name it, I've probably tried it. I even managed to learn from one post that "Limit Capture Framerate" in the Game Capture Properties can help and was really relying on that, but it actually made the footage worse.

What I simply absolutely fail to see is how people manage to upload such smooth frame transitions for this game with (in certain cases) more limited hardware than what I am utilizing now? One user on Reddit speculated that it could be post-processing. I guess that this is (in a way) my first question: Can choppy video be post-processed to look some smooth in some kind of software? I use Sony Vegas and have very basic skills when it comes to it, and have never heard of anything like this...

One other explanation on the internet that got my attention was referring to the use of different mouse sensitivity (DPI). Now, I'm not a professional gamer that has lowered DPI where the mouse feels like a dumbell and therefore when i look around the screen, it is especially jittery... Moving simply with the keyboard seems to have less frame pacing in the OBS footage that I have. This is my second question: Can the mouse DPI really affect footage like that in a such negative way? Now I am sorry for some of these questions but with all honesty I am kind of stumped here to say the least...

I was comparing more YT content and one famous gamer had his frames completely uncapped in the footage (with the FPS count shown) and the video was still extremely good, no jitter or anything like that.... I was told that if you want smooth frame transition, you need to record at even frame rates (i.e, a 120 framerate recorded to 60 FPS will look better than 165 or what have you, especially when the frames are fluctuating +/- 20 frames from time to time). This got me extremely confused... Maybe it's because these YouTuber folk have a dual set-up and that somehow affects everything? Maybe it's because they stream first and only then upload that material from Twitch to YouTube? It sounds maybe silly but I don't know what to think anymore quite frankly.

Also one question that I could never clarify (and somebody might misunderstand what i mean but here goes) is this: If you try out different monitor Refresh Rate options while recording, or NVidia G-Sync Enabled, does that incorporate (for a lack of a better word) and goes into the OBS recording? So if you have a monitor running and recording at 120 Hz during one footage and then at 144 Hz during the other one, will that affect the recording for all people that view it? From what I understand no it won't, but i just want to clarify this because im kind of confused at this moment.

I'm trying to think of any other additional information that I could give to get better advice but this is probably about it. I've tried all kinds of OBS Settings, Simple Mode and have then since switched to Advanced Mode (you can see in the log file) - there's honestly no discernible difference... I use a Portable Samsung T5 as the storage for the recordings... It doesn't seem to throttle or anything because there's no dropped frames in the log. What else to add? The game is basically "Choppy" for me during gameplay and in the video it's even snappier because of 60 frames vs 120 that i capped the game to. That's about all iCcan add currently and I would love to hear any advice, at this point it would be indescribably welcome! I'm just stunned to see that people of different calibers (starting from youtubers, streamers and pros and ending with guys that made just one video and that's all they will ever upload) don't have this issue whereas I do and nothing seems to help.

On a sidenote, the memory leakage at the end of the log was related to some questionable yet cool video camera effects and is not relevant to my main questions since I had all of these issues prior to having the video camera effects enabled. So basically, can anybody share their two cents in regards to the questions that I asked? Can post processing improve raw footage recorded in obs? Does monitor refresh rate affect the actual obs recordings, can mouse sensitivity cause footage to look bad by causing snappy frame transitions? Sorry for the bump but this is important to me, thank you

To answer your question about post-processing video the answer is yes. I follow a drone thread where the main complaint about video footage is that the video camera produces VFR (variable frame rate video). This shows up when the drone is yawing as a video stutter, one of the thread members produced a short program to convert VFR video to CFR (constant frame rate) video. Interesting aside but probably not related to your problem at all.

Thank you for your reply. This does sound interesting. Probably you are right, it's not quite comparable to my issue since at the end of the day, my OBS recordings are in 60FPS, but obviously a game cannot in any way maintain such stable frames, regardless of the graphical settings, frames will fluctuate (not below 60 FPS, but that's irrelevant, frames can drop from 120 to 100-110, etc)
