Question / Help 20% to 25% CPU Usage on NVENC as well as some dropped frames.

[Krank_Pupp]

Not really much else to say here is the log for you guys. Also I dont really understand too much of the lingo so if someone could walk me through it would be AMAZING. If your reading this in the future and have the same issue will say what worked for me at the bottom ;).

You're overloading your encoder.

I would suggest turning these two expensive features off.

Otherwise you may need to downgrade to either 1080p30 or 720p60. 1080p60 in a single PC setup with a 1070 can be challenging, especially with high motion content.

 

[Krank_Pupp]

Hey I turned off those 2 things and downgraded to 720p60 im still seeing the same high cpu usage with little to no improvement. Whats next boss?

 

[Krank_Pupp]

OK so I figured something out. My webcam increases cpu usage by 10% to 15% ALONE. I have a Logitech C922x Pro Stream Webcam at 720p60 and have also tried it at 730p30 doesnt seem to change much.

 

[Narcogen]

I would remove the driver for that and reinstall it then because that's probably not normal.
