I was previously using NVENC encoding, but I wanted to actually utilize my Threadripper as I noticed OBS never went over 10% utilization on the CPU during stream and I was having some issues trying to push 2K at 144FPS in Apex. I wanted to offload the streaming encoding to the CPU so I can dedicate the GPU to the game. Therein lies the testing.
I found myself playing Heroes of the Storm last night and tried to stream with these new settings. Almost immediately I started experiencing crashes and the entire stream would just lock up and stop broadcasting. Looking at my CPU utilization it never went over 30% and Heroes of the Storm was doing something interesting that I hadn't seen the other games do. While I was monitoring my CPU, GPU, bitrate, network traffic, etc, HotS would use 4 cores + 1 random core further down.
When I would open HotS, the stream would start choking. As soon as I closed it, it would level out. Opening Overwatch, Apex Legends, and Deep Rock Galactic all did just find on the settings listed above. Therein, why is HotS the troublemaker? Is it becasue it's now a #dedgame? 😛
