Hi OBS Community,
I have been experiencing this issue on my home built desktop PC for some time now, and after periodically attempting to research, troubleshoot and resolve over the past few months, I am turning to the community for any help or suggestions. Essentially, every time I boot up OBS and begin streaming to Twitch (has not occurred with local recordings, but TBH I have not thoroughly tested them to rule it out)--without fail--my entire PC will lock up after some period of time. It could be anywhere from 2 minutes to 50 minutes, but eventually the input and output will completely freeze forcing me to reboot the machine.
As mentioned in the title, please see one such example log:
They all typically end with those last couple of rows immediately preceding a lockup. Unfortunately, I cannot tell if the "stall" is a cause or if it is merely a symptom of the fact the the PC froze =\
Some background:
I have looked through the suggested settings and read a few guides, and I have tried a variety of different settings either aimed to optimize or increase performance at the sake of decreasing quality (e.g. FPS, bitrates, x264 presets, resolution downscale, different games, etc). The above settings have given the highest average time before a crash, but it is still not acceptable. Before I am asked: yes, I read the analyzer's suggestions--they were both minor items, but I have tried using the default x264 CPU presets, and the "ultrafast" setting seems to increase the average time before the PC freezes. Also, I have tried using a LAN cable vs wireless--seems to have little/no impact. My speedtests today were averaging around 15 down / 3 up.
I have recently upgraded to the graphics card listed in the log, and it works great while not streaming (i.e. no crashes when playing--and yes, the drivers are up to date). The CPU is older, but it should not be causing the PC to freeze with the scaled down OBS settings. Any constructive suggestions/help is greatly appreciated =]
