Question / Help OBS no longer hold 60fps during preivew only

[Shawty KING]

Hey there,
My OBS no longer holds 60fps PERIOD. Whether the app is just open or if I stream or record. My last stream was a month ago and at that time I had no issues with a solid 720p60 stream. This is a dedicated streaming pc btw so I don't know what changed. I havent touched the system since that last stream and I especially think its odd that the preview won't hold 60 while doing nothing but showing a preview. Thanks for any insight!

turn on Vsync in game

its not the game unfourtunately. dual pc setup. Anything being fed to the hd60pro is not holding 60fps on the streaming pc. My consoles show the same issue. OBS itself shows a fps from 35-45 even if I just have the preview up no stream/recording. Thanks though.

I just looked at your log again, and I noticed your Graphics card is a NVIDIA GeForce GT 730. And you are using the NVENC codec.

Look at these lines from from your log.

21:06:05.697: Output 'adv_file_output': Number of skipped frames due to encoding lag: 11 (0.1%)
21:06:05.697: Output 'adv_file_output': Number of lagged frames due to rendering lag/stalls: 4238 (45.5%)

Frames are either dropped to 'encoding lag' or 'rendering lag'

Encoding lag means your CPU is dropping frames
Rendering lag means your GPU is dropping frames

As you can see your GPU is causing you to drop frames. Which makes sense because the GT 730 is a very weak card. As it does support NVENC, it is too slow to encode to video very well.

If you are doing local recordings, you can record at very high quality with very little frame drop on the same PC. Encoding video doesn't use a lot of processing power, compressing video is what uses a lot of processing video. Compressing decreases file size while keeping quality good, which is great for streaming, but not ideal for local recordings since they are generally edited and re-encoded anyway.

If you are going to record on your second PC anyway, you would have to use x264 or Quicksync. Try using quicksync and the rest of your settings the same.

If you are still getting this issue upload another log using Quicksync and I'll take a look.
