Videos turn out real laggy with my RTX 2070 Super

I've been trying to use OBS for a couple of months now and I just can't get it to work. Even on simple games like terraira, after about 20 minutes I get the overload message and the video turns out really laggy. Ive tried to many different things and i just cant get it to work at 1080p 60fps.

Heres a list of things I've done:

-tried using encoder x264 and NIVIDIA NVEMC H.
-Changed the bitrate
-Changed the rate control
-turned on and off look ahead and psycho visual turning
-tried messing with the downscale filter
-Turned off windows game mode
-uninstalled and reinstalled obs and completely getting rid of the left over files when i installed it

Another note:

I have 2 monitors. ones 144hz and the other is 75hz. I've seen a lot of people say the smaller Hz monitor could mess up the recording. I have tried unplugging the 75 Hz monitor from the PC and it made no difference in my problem.

Here are my computer specs

-Intel i7 9700f
-RTX 2070 SUPER (8GB)
-16gb of ram (2 sticks of DDR4)
-445GB SSD (OBS is installed on the SSD)
-1 TB hard drive
- B360 motherboard
- 650 watt PSU

I will have a log file that is from a recording of DOOM Eternal linked to this


Thank you for the Help!
 
The refresh rates of your monitors are going to cause stuttering. Either run them at 120Hz & 60Hz or you can try updating to Windows 2004 to see if it helps. I can't tell you if the fix in 2004 works as I'm still running Windows 1903 & I just deferred updates for another month this morning.

As far as your dropped frames. Switch your Preset to Quality & turn off Psycho Visual Tuning.

I also would record using CQP & start with CQ @ 18. If you want higher quality lower the CQ & if you want smaller files raise the CQ. Right now, you're just wasting disc space....

A few more suggestions:

Set all your sampling rates so they match
16:38:47.887: OBS 25.0.8 (64-bit, windows)
16:38:47.887: ---------------------------------
16:38:47.902: ---------------------------------
16:38:47.902: audio settings reset:
16:38:47.902: samples per sec: 44100
16:38:47.902: speakers: 2
16:38:48.628: WASAPI: Device 'Speakers (7.1 Surround Sound)' [48000 Hz] initialized
16:38:48.628: [Loaded global audio device]: 'Desktop Audio'
16:38:48.657: WASAPI: Device 'VoiceMeeter Output (VB-Audio VoiceMeeter VAIO)' [44100 Hz] initialized
16:38:48.657: [Loaded global audio device]: 'Mic/Aux'

Change the Color Space setting to 709
16:38:48.341: YUV mode: 601/Partial

Create another Scene & move either your Game or Monitor Capture to it
16:38:49.309: Loaded scenes:
16:38:49.309: - scene 'Scene':
16:38:49.309: - source: 'Display Capture' (monitor_capture)
16:38:49.309: - source: 'Game Capture' (game_capture)
16:38:49.309: - source: 'Image' (image_source)
 
Take a look at your recording settings, the Rescale Output box is checked. Uncheck it & then record again but make sure you're using the exact settings I posted above.

17:32:17.188: [jim-nvenc: 'recording_h264'] scaling enabled, falling back to ffmpeg

Here's something else you can check too

How can I see how many NVENC sessions are in use?
How can I see live encoding stats?

Open a command prompt and paste/type:
nvidia-smi.exe encodersessions
 
Open it & compare it to the RTX2080 picture on the download page. See any major differences?

I have a 6700k/GTX-1660 Super running the same driver as you. I'm recording NVENC Max Quality CQP18 with Look Ahead/Psycho on. Your GPU should be doing the same & it's clearly not. This is NVENC sessions/stats info.

Looks good but that just means more troubleshooting....

Has OBS ever run correctly on this PC? Are there any cooling issues?

I would create a completely new Profile in OBS, delete everything (scene/souces) & just add one scene/source & give it a shot. Keep on eye on Task Manager, GPU encode should be roughly 20%. Run the sessions/stats command too.
 
How full is your HD? I still have my recording running & I started dropping frames. My SSD was almost full, deleted 20GB's frame drop stopped. I assume you're saving to your SSD, it's not that large....
 
Run OBS as admin, and change your CQP value off of 2. The encoding lag you're seeing is most likely a result of the encoder producing such a large output that it's not being written to your storage device fast enough. Use CQP of 20 for testing right now.
 
I think it worked for a little while when I first got it a few months ago. also my sad has 45.5 GB of free space and my HHD has 143 gb of free space. when encoding, my gpu seemed to stay at 14% but spiked twice which resulted in the recording lagging, and the sound effects in doom eternal to stop playing

also thank you carlmmii ill try that
 
UPDATE:

I took both of your advices and I'm still having problems... the encoder showed it had spike issues. some rather small but still resulting in lag issues, and twice resulted in a spike that went from 0-60% shown right below. (also it usually say around 13-14%)

You turned Psychovisual tuning back on. This is a CUDA-accelerated function, which can cause issues, especially with a demanding game like Doom Eternal.
