No output session in log. Open OBS, start recording or streaming, observe your issue, stop the output session, then upload the current log before quitting OBS.

Not seeing any issues in that log. No rendering or encoding lag in the log.

You may wish to turn that on if OBS operation is affecting your other apps' framerate. This feature was broken in earlier versions of Windows but is now fixed.

Could this be the problem?

I don't believe that affects your framerate, no. Running as admin is required to game capture applications that are also running as admin.

Your log shows that you were trying to game capture Internet Explorer fullscreen:

15:09:06.896: Switched to scene 'Games'
15:09:06.896: [game-capture: 'Game Capture'] attempting to hook fullscreen process: explorer.exe
15:09:06.896: [game-capture: 'Game Capture'] cannot capture explorer.exe due to being blacklisted

OBS does not allow some programs to be captured in game capture mode including:
  • Chrome
  • Internet Explorer
  • Firefox
  • Skype
  • Discord
  • UPlay
  • Steam
  • Task Manager
This is why you are getting a black screen in preview and the error message in the log.

You have to use display capture instead.

I read the second log. My response was from looking at it and seeing this:

15:20:41.972: Switched to scene 'Games'
15:20:41.972: [game-capture: 'Game Capture'] attempting to hook fullscreen process: explorer.exe
15:20:41.972: [game-capture: 'Game Capture'] cannot capture explorer.exe due to being blacklisted

That’s weird because that’s not what it should be... on my end it’s javaw.exe, which is what it’s supposed to be

Another thing you should consider changing.

You are trying to do 1440p recordings at 60FPS:

15:20:41.405: video settings reset:
15:20:41.405: base resolution: 2560x1440
15:20:41.405: output resolution: 2560x1440
15:20:41.405: downscale filter: Lanczos
15:20:41.405: fps: 60/1
15:20:41.405: format: NV12
15:20:41.405: YUV mode: 709/Partial

Your bitrate is 40000.

15:20:46.094: [NVENC encoder: 'recording_h264'] settings:
15:20:46.094: rate_control: CBR
15:20:46.094: bitrate: 40000
15:20:46.094: cqp: 0
15:20:46.094: keyint: 120
15:20:46.094: preset: hq
15:20:46.094: profile: high
15:20:46.094: width: 2560
15:20:46.094: height: 1440
15:20:46.094: 2-pass: true
15:20:46.094: b-frames: 2

Look at YouTube recommendations for SDR at 1440p for 60FPS as a guide:
https://support.google.com/youtube/answer/1722171?hl=en

They only want up to 24000 bitrate for 1440p@60FPS, so 40000 is too big. Change it to 24000 to reduce CPU/GPU usage and the amount of upload bandwidth if you plan on delivering to YouTube.

I could but i have always heard to set the bitrate higher when recording and render it at 24mbps after edits.

Everybody's response so far is based on looking at your log and giving you advice on what problems they see. Your log shows nothing in regards to encoding or rendering lag to prevent you from your 1440p@60FPS setting.

You got a Ryzen 3700X and RTX 2080 and there should be no reason why you can't record at 60FPS at 1080p.

What exactly does "I can't get 60FPS video" mean? Be more explicit. What exact steps are you doing to determine you are getting less than 60FPS? The logs don't say you aren't.

You should not be directly concerned with bitrate when recording locally and then post-processing. You should be concerned with quality, which is what CQP rate control does. Setting a bitrate, for any given rate, means bits wasted when the encoder doesn't need them, and no quality higher than the selected bitrate when the encoder needs more.

CQP sets a constant quality level, and uses more or less bits when necessary to keep that quality level.

I recorded at 144fps (the refresh rate of my monitor) and I fixed it. But what should I set my CQ level to?

Start with 15 and adjust if needed. Lower is higher quality, larger files. Higher is lower quality, smaller files.
