Gameplay videos are laggy

Hey guys,

First of all: I'm German (so sorry if my English is not the best sometimes).

I have a problem with the recording of gameplay videos with OBS. It doesn't matter which settings I set, the recorded video is always looking bad and it lags as hell.
I don't know what to do.

I added one Scene with two sources in OBS: Game recording and my Webcam. So the Gameplay from e.g. GTA 5 should be recorded and myself while gaming.
GTA 5 is running under 144 FPS at maximum (but sometimes crashes under 100 FPS .. didn't fixed this as well, but this is another problem).

My OBS settings are as followed:

Type: Standard
Recording Format: MPEG-4 (.mp4)
Video Encoder: NVIDIA NVENC H.264

Ecoder Settings:
Rate Control: CBR
Bitrate: 10000 Kbps
Keyframe: 2s
Preset: Slow
Tuning: High Quality
Look-ahead: Not set
Psycho Visual Tuning: Set
GPU: 0
Max B-frames: 2

Video Settings are as followed:
Base (Canvas) Resolution: 1920x1080
Output (Scaled) Resolution: 1920x1080
Common FPS Values: 60

I tried changing the Encoder settings but nothing worked and I don't understand it.
My computer is good enough to handle all this stuff:

Windows 10 22H2
AMD Ryzen 7 5800X 8-Core Processor 3.80 GHz
32 GB RAM
Graphic card: ASUS GeForce RTX 4070 Ti Super (with 16 GB VRAM)


Can someone help me?
If something is neccessary please tell me and i will deliver it.

Thanks in advance :)

Please, make test recording and attach OBS log-file to see what kind of lag you have (rendering or encoding).

Thanks for your answer.

I tried something else while waiting. I set my refresh rate (in GTA 5 ingame) from 144 to 60 FPS).
Now recording is much smoother (but now it looks a bit blurred).

Here's the logfile:

Before changing i had a refresh rate of 144 ingame .. but OBS was set to 60 FPS.
Is this the problem?

I read the discussion and it took a bit of time to understand the problem with the motherboard and the NVME.
As I understand the problem was that his GPU was limited because of the NVME, because they're sharing the bandwith and his card was running with x8 instead of x16.

I checked the manual of my Board (ASUS ROG Crosshair Formular VIII) and I couldn't find anything about shared bandwith.
Tried to find something on Google but could'nt find anything.
The only thing I found was the advice to plug in the graphics card in the first PCI port (i already did this).

It would be interesting to test if my graphic card is using full speed on PCI but I have absolutely no idea what to check or what informations are helpful in GPU-Z or CPU-Z or which other tool.


I am a little bit frustrated at the moment.. I really wanna start recording gameplays, because it was my dream for years.
And now I have a really good computer and nothing works as I expected :(

Maybe guides for OBS will help you more:

Guides (OBS Studio)

Some are about high quality recordings, some about high fps recordings, some about capture cards.

CBR rate controls during encoding is good for streaming. For local recordings users usually use CRF, CQP methods to control rate (bigger file size but better control over quality).
