LiveStream LAG with High End - PC

[tensor097]

Good afternoon.

I've always streamed on my old computer.
However, today my new computer arrived, and I installed OBS again.
It turns out that when I start streaming, the whole stream jams, I'm playing perfectly, but the whole stream is jammed.
The PC is very good, I don't see any reason why this should happen.

The log shows a little bit of skipped frames due to rendering lag (a sign of gpu overload) and a little bit of skipped frames due to encoding lag (a sign of encoder overload).
Since you have one of the most powerful gpu and cpu available, this is not usual behavior.
There are no apparent network issues, so it is something with your hardware or with something except obs fully consuming every cpu/gpu resource. Make sure the thing you capture (probably a game) isn't running without fps limit. Not limiting the game means it can steal every gpu resource and OBS is starving for resources.

Since your computer is brand new and didn't yet prove it's working properly, I recommend you run local benchmark tests and ensure the hardware is working properly. Make sure the GPU card is sitting in the proper pci-e slot, especially if it's a custom built PC and not some stock PC. Usually, the gpu must be placed into the slot nearest to the CPU. There is no choice, there is only one slot possible. Consult the motherboard manual. Run a test app like gpu-z and make sure the pci-e speed of that GPU is actually x16 under load.
Check for overheating.
Check CPU and GPU performance and see if results match expected performance.
Make sure the Intel Chipset driver is installed.
Make sure the proper audio driver released by the motherboard vendor for your motherboard is installed.
The proper Nvidia driver is installed according to your log, so this is probably not the issue.
It may help to check the motherboard vendor website and check for bios updates. The newest 13th and 14th generation Intel i9 CPUs got some bios updates lately.

Tools I used for checking my PC (no particular order):

cpu-z
gpu-z
Intel Processor Diagnostic Tool
Furmark
CoreTemp
hwinfo64

For checking the GPU, run a Furmark stress test in windowed mode and while it's running inspect gpu power consumption and gpu temperature with gpu-z or hwinfo64. The GPU is running properly if it's reaching the specified GPU's power limit and temperature limit and staying there while the test is running. Not higher, but also not lower. This is also a good test of the power supply.

I've done all these tests, which is strange.
Memory tests passed,
the cpu doesn't go above 60celcius and the graphics doesn't go above 65celcius.
É realmente algo estranho.

Disable HDR, monitor 1

Monitors 2 & 3 should be running @ 60HZ, not 75. Going to cause stuttering.

Fix your Scenes. There should only be (1) Display, Game or Window capture per.

- You should give OBS administrator run
- Enable HAGS. On the RTX 40 series it is needed to generate DLSS 3.0 frames
- Enable Maximum Power Performance Modes in Windows and NVIDIA Control Panel
- Disable Game DVR and similar recording options
- Disable dynamic bitrate. You don't need this.
- I recommend using a wired Internet connection! Avoid streaming over Wi-Fi
- The problem may also be caused by your media sources. Try turning them off.
- Minimize the number of processes in Windows, close unnecessary programs. Basically, all you need is just the game and OBS.
- You have powerful hardware, but avoid loading the CPU/GPU to 100%, this can lead to overload of the encoder.
- Psycho Visual Tuning should be turned on. It reduces blocking in dynamic fragments by redistributing the bitrate.

As previously noted, your monitor supports HDR10. It is recommended to disable. It is also recommended to make the monitors refresh rate a multiple of 60 or an even number.(60/120/240).
