Question / Help Recordings are laggy and look like the frames are rubberbanding

Hey,

I'm genuinely sorry if this is some obvious easy to fix problem but I ran out of options to try.
I spent the past week trying to isolate the cause of this issue but it seems to be impossible for me to fix on my own without help.

What I tried so far:
  • running OBS as Admin / not as Admin
  • turning Windows game mode on / off
  • HDD / SSD
  • install older Nvidia drivers (after running DDU)
  • install just the graphic drivers without the other crap like telemetry etc. (thanks to NVSlimmer)
  • record with OBS Studio, Streamelements OBS, Slobs
  • old and new NVENC
  • CBR, VBR, QCP
  • with and without Psycho Visual Tuning
  • limit ingame frames to 64 via Nvidia control panel
  • turn Vsync on / off via Nvidia control panel
My GPU is at ~70% load (monitored with Afterburner because the Task Manager seems to be buggy) while running GTA5 & recording with QCP set to 14

Simple output mode. Indistinguishable quality. Large file size.

Afterburner is on the known conflicts list.

"Simple output mode. Indistinguishable quality. Large file size."

I will try that tomorrow and Afterburner wasn't running the whole time, I actually only installed it after getting suspicious about the ~20% GPU load the Task Manager was showing.

So a problem comes to me again, the game was running smoothly at 50 fps (i recorded at 50 fps too) and the audio is fine but the video just freezes every few seconds, I searched, people say I should lower the quality. Thanks for the information.

If you have a problem please make your own post and include a logfile.

Not seeing any significant frame drop in those logs. The most I see is this:

16:36:30.395: Video stopped, number of skipped frames due to encoding lag: 13/3601 (0.4%)

Are you playing back your local recordings, or only looking at YouTube? Because YT re-encodes everything.

I do see some judder... what refresh rate(s) are your monitors running at?

I have two Asus VG248QE 144Hz screens and usually run them both at max refreshrate but because of these problems I've also tested to run them at 120Hz & 85Hz without improvement.

The judder is actually even (a bit) worse or at least more noticeable in the raw video before rendering and uploading to youtube.

It drives me crazy.. I got rid of every software that could cause this and tried every Nvidia driver since early November (441.12).

It is not possible to avoid judder downsampling 144hz to 60 because it does not go evenly. There will be an uneven skipping of frames to get down to the target frame rate, and this will cause constant and noticeable effects.

There is also currently an issue in Windows itself running two displays at different refresh rates.

85 would not be an improvement, as it does also not divide evenly down to 60.

120 for both should show improvement because at least that pulls down to 60hz evenly (just drop every other frame), but best would be both the same, both 60hz. Even if you ran one display at 120 or 60, Windows can have a problem if you're running another display at a different frame rate, even if that display is running at an even multiple like 120.

This can be exacerbated if OBS is running its preview screen on a display with a high refresh rate or one that does not evenly divide down to 60.

I have limited the ingame frames to 60, 62 and 64 frames I don't let GTA run unlimeted. I still have some videos from early December without the judder. I was in a hospital in the meantime and all of a sudden without any changes in my system or installing new software this stuttering happens no matter which game even in simple 8bit pixel games.

I run my screens always at the same refresh rates that's the sole reason why I got the second 144Hz screen back in last August because I noticed theses problems with my old 60Hz second screen.

Edit: also tested it without the preview but it makes no difference.

Nothing in the hotfix versions should have changed that. Did you change the install path?

No, the same as usual.
But I just remembered that I can't be 100% sure that OBS 24.0.3 was at fault because I installed the latest optional windows update (KB4532695) prior to testing 24.0.0

I'll test it again tomorrow with all versions from 24.0.0 up to 0.3 because I want to know if it was some problem with windows.

First off I wanna say that I was wrong and that 24.0.0 wasn't the solution, the one recording I took with it on monday was just a bit less laggy.

I took the time and effort to test literally anything I could imagine to fix this over the past week and I just wanna give up now...
Tested all the way back to OBS 20.0 (also all the rc versions) each version with each Nvidia driver dating back to 431.36 from last July.

I tried all kinds of recording settings and got rid of every unnecessary piece of software, running my screens at 60, 85, 120 & 144Hz, limiting ingame frames to 60, running the game with VSync on / off, game mode on / off, turning the preview off but nothing makes a difference the problem still persists! -_-
Btw it's every game not just GTA I even recorded some low end graphic 8 Bit games with lots of motions and even there it's noticeable.

But now comes the funny thing I installed Geforce Experience today to test shadowplay and even the shadowplay recordings are laggy like wtf!? Is something fundamentally flawed with my system?

Its not just you. I been trying to fix this for the past 2 weeks nows. Don't know what to do any more.
Everytime i think i fixed it starts to stutter like crazy few hours later.

With the rendered & compressed video on youtube it's not as obvious as with the raw recording but at ~40 sec. to 46 sec. it's pretty noticeable focussing on the buildings left & right also at 1:52 - 2:00. I can send you the raw files if you want.

I tried VLC, KMPlayer and Media Player Classic but it makes no difference.

I guess nobody knows a solution.. I just don't get it because all my recordings from early to mid december before my hospital stay were buttery smooth and nothing about my system has changed, this is so damn frustrating.
