Question / Help This just recently started happening

[greedmachine247]

Anyways things were going fine, and then one day I would get the stream output failed message, asking if my NVENC drivers were up to date, everything was and I can't seem to get this message to go away unless I change my encoder to software and that does not seem to work very well, Honestly I'm not even sure this is the correct format for posting a log, was seriously hoping I'd never be on here asking for help lol, I know this forum sees a lot of posts like this but I could not find a solution to my issue

Your nvidia drivers are NOT up to date.

Your 840M uses a GM108 chipset. This chipset does not have NVENC support.

I appreciate the quick response, what happened overnight that would cause this error though? I was streaming just fine one night, went to bed and went to stream the next day and I started getting this? No changes to anything, just waking the pc up and tried to get on, and nothing, any ideas for a possible workaround since something happened?

Switch to x264 as your output setting.

 

[greedmachine247]

I tried that the other day but I don't think the output was very good, like my processor can't keep up?

You have no other choice but to use software encoding on the computer you are running on.

- Your 840M is extremly slow, outdated.
Passmark rating (891):
https://www.videocardbenchmark.net/gpu.php?gpu=GeForce+840M

Compare it to the higher end GPUs today:

Your GPU is nowhere near what everybody is using to stream and play games.
A GTX 1050Ti (Passmark 5781), is 650% faster. That needs to be your baseline.

Your i7 5500U is a mobile CPU that only has 2 cores/4 threads. Mobile CPUs are good for light computing on the go.

Your laptop wasn't designed to stream and play games concurrently with the hardware it has in it.
