Unfortunately while that contains the start of a recording session, it doesn't have the end (where the diagnostic data about lagged/skipped frames would be, along with the timing tree). If you ended the recording and closed OBS, you can go to %appdata%\obs-studio\logs and grab the same filename, upload it again, and it should have that information.
While you're running OBS as Admin, the GPU workaround doesn't always work... Apex Legends is pretty well-known for being GPU-hoggy. I'd need the logfile to confirm it, but the fix may be to turn down the in-game settings, use a frame limiter and/or vsync to mitigate the game load on the GPU. Again, just speculating on most-common causes, will need the log to confirm or find other causes. :)
You are using the Max Quality and Psychovisual Tuning options, which can cause encoding overload even in situations where it should not. Use the Quality preset instead, and turn Lookahead+Psychovisual Tuning OFF. These all use CUDA cores, and tend to cause random encoding overloads for no good reason.
You're also recording using CBR, which you should not do, and recording to MP4 directly, which you should NEVER do
for any reason.
Record to MKV and remux to MP4 if you need it for editing using the OBS File menu, Remux Recordings.
Record using CQP/CRF. These are quality-target based encoder methods that will use as much or as little bitrate as is needed to maintain a given image quality level; no wasting bitrate on slow-motion simple scenes, no bitrate-choking on fast motion/complex scenes. CQP 22 is a good starting point. CQP 16 is effectively visually lossless. CQP 12 should only be used if you plan to edit the video, to minimize re-encoding artifacts. Below 12 should not be used unless you have a VERY specific reason. The lower the CQP number, the better the image quality (CQP is how far the encode can deviate from perfect, uncompressed frames) but the file sizes get
huge, FAST.
The CoreAudio AAC encoder would not cause this. It's purely an audio quality improvement over the built-in OBS AAC encoder. If you'd like to install CA, it's quite easy. Here's a guide:
First of all, if you have iTunes or QuickTime installed, chances are you are already using the CoreAudio AAC encoder in OBS-Studio. But if you normally do not use or install any of those, there is another way to enable it. All we need is the...
