stuttering sync problems with new nvidia drivers.

[Bar_be_que]

So I should have done a log file when the problem happen however i was on driver 572.70 and i was getting this weird lag issue with preview in obs studio latestest build 31.0.3. I will upload file. I then starting rolling back driver by driver and am now on 551. 76. Hardware is intel i7 10700 k and a nvidia 1060 6gb graphics card. This can be replicated on my other rig as well. amd 7900x and 4070 ti super. but my streaming rig is the 10700k. Any thoughts? I uploaded current log when it was doing to the obs studio discord forums and log showed now errors. Figured i would post in case anyone is having issues it's much better on 551.76 and since obs says you may have to run atleast that version for obs i have tested lower. So putting this on the radar. Thanks all. Oh so can i upload a MKV file? Or how could i post a clip. so this test shows all grey letters when everything is in sync. You can try it all for your sell just google vertical sync test. but if i could do the video it would be easier to show. when it shows the colors its not in sync and changing to a older driver fixes the issues. I don't feel it obs related so much but the stutters are def messing with the encoder. So if anyone is having issues like this maybe revert back. Just though i would put in on the radar. Thanks all.

My guess is that most of us hide OBS from itself. Look for File > Settings > Hide OBS from Screen Capture; I unchecked that selection, which makes it run like the older OBS builds and my performance increased drastically. Most people will not do this and assume that it should be fine, but once I turned this setting back on it was a nightmare to record with.

With this off (by default), I can even run OBS under NVIDIA's Low Latency conditions now. There were some jitter, but not like it was when I hid OBS from itself. I attached my Profiler Results from two logs to compare.


This is a log with OBS Hiding from the Capture = True

There are some areas of interest. With the option set to enabled, the shader compliation is 43.194 ms, but with it turned off, its 433.494 ms.

If you look at the output frames and audio:

----------------------------------------------------------------------------------------------

OBS Hide from Capture Set to Enabled:

output_frame: min=0.042 ms, median=0.101 ms, max=18.854 ms, 99th percentile=0.264 ms

audio_thread(Audio): min=0.004 ms, median=0.012 ms, max=18.727 ms, 99th percentile=0.091 ms

------------------------------------------------------------------------------------------------

OBS Hide from Capture Set to Disabled:

output_frame: min=0.033 ms, median=0.099 ms, max=0.808 ms, 99th percentile=0.236 ms

audio_thread(Audio): min=0.004 ms, median=0.012 ms, max=0.406 ms, 99th percentile=0.076 ms

-------------------------------------------------------------------------------------------------
From this, and I'm sure that I could pick a clear winner for me (which is to keep the setting turned off), the shaders took less time to compile when it's enabled; Since its hiding from the capture and takes less time to load OBS. However, turning this setting off took more time to load the shaders (maybe there are more shaders being build by OBS and the NVIDIA driver) and it feels as though more functionality is loading.

The tradeoff is "I want to hide OBS from being captured because I don't want people to see it" or "it takes less time to load OBS, so this way is better" when in fact it's making recordings worse.

Just gave it a try and no difference on my end. I am thinking that the out of sync is from the nvidia drivers causing stutters and that is causing frame pacing to go crazy in obs. I'll try some older drivers but it's recommended you use driver for obs studio current release so if i go back further could cause other issues. Windows, nvidia, windows 11 sure are all really buggy right now with all sorts of different things. Just thought I would throw it out there in case anyone else trys vertical sync test and gets the same issues on a duel pc stream setup.

Update!!!!!



Okay guys i found the fix for my setup.

My pc specs are

amd 7900x
4070 ti super
windows 10
obs studio 31.0.2
monitor is a dell 2524h 240 hz
gysnc and free sync are off. Yes i get some screen tearing

I changed in the nvdia control panel left hand side. " adjust image settings with preview" i then choose use " use the advanced 3d image settings"

Next under manage 3d settings I leave everything to driver default except "power managment mode" I changed it to "Prefer maximum performance". This will make your gpu run full clock all the time! I then rebooted computer and ther vertical sync test was smooth as silk. Here is website i have been talking about. You want to see all grey. If any blue or red flashes there is something going on.

I now No longer have issues with the preview in obs studio picking up those stutters and throwing it out of sync. I no don't have any stutters now at all in any of my videos or streams.


Conclusion to this. I recently upgraded from a 3070 ti to my now 4070 ti super. The only think i can think of the cause is that when our graphics card are in optimal mode setting in the nvida control panel settings that the idle 210mhz on the 4070ti is lower then what it was on the 3070 ti causing out of sync issues for my hi refreshrate of 240hz. People may not notice this on lower refreshrate monitors like 180hz, 165hz 144hz as it's not a hard on the gpu to match this frame rate. I am not talking about game fps just the system overall refreshrate so don't get confused. It can be tough on a card to hit that refreshrate for graphics cards. I hope this help some people causing all the stutters.

If you were to do the math now that was talked about and set fracitonal fps so forth your encoding it should be perfect a perfect copy! I just do common fps 60 though cause 240 goes into 60 so I don't have any issues. Thanks all hope this helps!
