Question / Help Is my computer just too bad? Recorded gameplay file drops to single digit framerates at somepoint during the game

https://obsproject.com/logs/56Ts-qgDt3WQa5w6 This is the log file, I've just downloaded OBS Studio and am trying to record, not stream for the moment. I've dropped the output scaled resolution to 960 x 540 and the scene is just the lenovo integrated webcam in the bottom right with League of Legends being the main window (and the cliend being displayed behind it).

My laptop has a Intel i5-6200U processor (2.4GHz, 2 cores), 8 gig ram, NVidia Geforce 940MX GPU

Running League of Legends, OBS, a couple of tabs of chrome, and task manager doesn't seem to be maxing out my ram, cpu or gpu (though i'm using software encoding so I don't think the gpu usage is relevant).

The encoded file is always fine to start with but at some point which could be anywhere from 8 to 20 minutes, this massive framerate drop occurs and the file becomes basically unwatchable.
 
The log analyzer doesn't show the "insufficient hardware" message for me on your log, so it's not so old that it is at or below the minimum requirements.

It still might be not up to the task you're asking of it; for that, you'd need to look at a log with a recording session in it.

Sorry, i thought i had, this one has a recording though https://obsproject.com/logs/_N7ommLn2hoICWty

34.9% lagged frames, better than usual but still...
 
Okay..

You're trying to use NVENC on a GPU that does not support it. Even if it did work, it would not be good at 1500 kbps CBR.

Your GPU is overloaded:

16:51:48.716: Output 'simple_file_output': Number of lagged frames due to rendering lag/stalls: 17927 (34.9%)

There's nothing really to do for this except to lower canvas resolution and cap framerate, as well as probably reduce visual effects in the game. 35% is a pretty unwatchable level of rendering lag. In fact, your CPU encoding lag is minor compared to the GPU overload. Keep in mind that particular threads on the GPU that do certain things can overload even if the GPU itself overrall is not overloaded.

Ah, so rendering lag just equates to gpu failings. Could it be from overheating too? why does it take up to 15 minutes sometimes for the rendering lag to affect the output? Also, although i haven't checked it out myself yet, a friend said that when i streamed it to twitch it was smooth the whole way through, does streaming render differently from rendering for recording?
 
Without the log from that particular session it's impossible to say. You can have different settings for streaming and recording, so it's possible that you've induced lag with one but not the other.

34% of frames lagging isn't marginal, though, and much lower levels are quite noticeable.
