I have been experiencing lots of crashes while using OBS to stream games like Apex, Division 2, and even BF4. Not sure if my setting are messed up or what but I can play all these games at very high settings. Thanks to anyone that can provide any help.
If you are using the CPU to do the streaming (x264 encoder) then get into your bios and set all the setting manually to safe normal settings because your mobo might be overclocking your system and might not be a stable as it should.
As @rgd1101 suggested, you should check the CPU/GPU temp. Also, in case if this due to issue on software side (OBS/GPU driver/Windows OS etc), you can check application events. Search for event ID 1000 for app crash and check which module is crashing.
