Im trying to Stream Lineage II / Pubg in 1080px60fps. Usually runs kinda smooth until i turn my camera angel and it seems like scaling/frames are being lost or something.

Video where it shows exactly what i mean: https://www.twitch.tv/videos/200642708

What ive tested

  • Changing bitrate everywhere from 2500 to 16000 (many diffrent stages)
  • seeing the diffrence between 720/1080, still same loss
  • Preset : HQ
  • Profile : High
  • Tested Rate control CBR / VBR, Vbr seems to be a tad better.
  • Gpu 0
  • B frames 2
  • Nvench H 264
  • Tried all scaling filters, not huge diffrence between them but bilinear seems to be best
  • tried 30/60 fps, both still not satisfactory.

Show us more log files, a log file that have streaming or recording information in it, which shows more information about what encoder settings is used as well as showing possible performance problem.

Looking at this log, it shows as using 720p 60fps NVENC 4500 Kbps with no frame drops. The problem might be that that quality of NVENC at low bit rates isn't as good as other encoders, like x264.

Can you try a different encoder like QuickSync or x264?
Quicksync for your CPU (i7 7700) might have better quality then NVENC.
x264 should work fine for 720p60, but 1080p60 may excessively drop frames from limited CPU cores and speed. SuperFast might work, at a cost of less quality.

Very fast motion have less quality due to constant bitrate as required for live stream. More bitrate may help, but Twitch's max bitrate for 1920x1080 60fps says 6000 at the time of looking at this. https://stream.twitch.tv/encoding/
