Differing outcomes from the same settings

[arkham]

I've been trying to use OBS to record my gameplay for a little while now, and recently I finally got all my settings to where the video looked smooth, was at the resolution I wanted, and didn't take up to much space after a lot of trial and error. However, the next day after I got the perfect recording, I recorded another gameplay with the same settings and the video looked very choppy, like it was at 20 or 30 fps even though it was set to 60. Everything else was the same, but since then I have not been able to figure out why it changed like that, or how to fix it.
(also I would include the log file, but I'm not sure how to upload a log file that was made prior to me making like 4 more)

For previous log files, go to Help->Log Files->Show Log Files, and that should open up the folder with your log files. Just attach whatever files look like viable candidates for the problem appearing.

ok, the first one (2021-03-16 23-35-39) is from the day it was working as intended, and the second (2021-03-17 23-20-00) is from the next day, in which I'm fairly certain that the settings were the same

Your main issue is from rendering lag. Run OBS as admin -- this will add OBS to the GPU priority list so it can compete with your game taking up all your GPU usage.

Also, in Settings->Output, turn off "Rescale output". This is forcing the encoder to fall back on the previous method of Nvenc. Switch off from low-latency as well... just leave quality at "Quality".

Turn on your stats window, and keep an eye on your frames lost due to rendering lag while you're recording. If you notice that you still have frames lost, you may need to limit your game's GPU usage (limit framerate, drop settings) so that you aren't sitting at 100% usage. Rendering lag is usually an indication that OBS doesn't have the resources available to grab frames within the 60fps timing window, which is usually caused by the game not letting OBS have what it needs to run.

Sorry this is so late, but it doesn't seem to have worked. I think ill just wait until I get a better CPU and graphics card. After all, I was just messing around with recording and wasn't super serious or anything. Thanks for the help though.
