I use to use OBS to stream and sometimes record, now i use shadowplay, obs can be great for recording however, it does take a lot of your CPU, and can cause you to lose frames. get an NVIDIA graphics card for Shadowplay, i find it way better
You need to restart PC, try it, if it doesnt work, sometimes mine bugs, and i have to open task manager, end any task relative to NVIDIA, and then re-open it, then have to turn shadow play back on
You were not close enough for them to hear a word you said, and if the chance they did hear you, it would be a very faint sound where its like a whisper. Therefor its basically RDM. Next time send a text or get closer. They shot because you shot.
