Hi,
For some reason my OBS randomly freezes and I get encoding and rendering lag.
I'm running two computers with capture cards hooked up.
One Black Magic Intensity Pro 4k - Gameplay, and one Avermedia LGX - Facecam
My dedicated streaming computer got an GTX 1050 for nvenc only.
GPU usage is about 40% when streaming, CPU usage is about 30-40%
But I'm getting sudden spikes in performance where my 1050 GPU suddenly drops to 0% and then spikes up to 100% before stabilizing at 40% again.

Again, I'm using a dedicated streaming rig.

Running OBS 23. RC2

NVIDIA NVENC H.264 (new)
CBR 6000
Max Quality
High
Look-ahead: yes
Psycho Visual Tuning: Yes
Max B-frames 4

Log attached.
What can I do?

Also seems like OBS is having problems if I flick my mouse around as well.
Bitrate spikes to 9k+ even though "Enforce streaming service encoder settings" are checked.

Best Regards.
Daniel Lange
