Been encountering an odd issue on a few games lately with using the rescale output functions for livestreams. I play and record in 4K and would typically stream in 1440. I'm on YouTube so 4K or 1440 streams are a thing and they usually look quite crispy.
Was having some issues with Dying Light 2 and For Honor in particular though and decided to mess with some settings and discovered that while playing in 4K, if I was streaming in 4K I had no lag. If I rescaled things down to 1080, also had no lag, but if I rescaled to 1440 we're suddenly taking trips to frame city.
This shouldn't be a hardware issue (3950x, EVGA 3080, 64gb memory) because otherwise Playing/Streaming in 4K simultaneously wouldn't be smooth. It's also not a bitrate issue as I'm on fiber and did the following bitrate tests using numbers pulled from YTs live encoding recommendations:
1080 @ 9000 bitrate = Smooth
1080 @ 18000 bitrate = Smooth
1440 @ 9000 bitrate = Laggy
1440 @ 18000 bitrate = Laggy
4k @ 30,000 bitrate = Smooth
The obvious solution is to just not stream those 2 titles at 1440 but I've never encountered an issue like this before and I'm curious for any thoughts. 2 logs from recent streams with the issue and one from this morning when I was doing the testing attached.
Streaming encoding is typically done with NVENC New, CBR, low-latency quality, high, look-ahead, psycho visual tuning, 4 max bframes.
