I'm running OBS Studio 27.0.1 and obs-ndi 4.9.0 on Windows 10. I added an "NDI Source" to a scene and use "NDI HX Camera" on iPhone as a source.
"Allow hardware acceleration" is enabled, but seems to not be used after start of OBS Studio:
- "Allow hardware acceleration" is enabled
- Start OBS Studio, CPU usage is 14-17%
- Disable "Allow hardware acceleration" in the NDI Source and save
- CPU usage is unchanged at 14-17%
- Enable "Allow hardware acceleration" in the NDI Source and save
- CPU usage drops to 3-6% (and stays there)
- Restart OBS Studio
- CPU usage is back at 14-17%
Settings in NDI Source:
