Can you upload a logfile after you have attempted a stream session please.
What is your in-game fps when streaming?
Also, what is your video card?

Remove scenecut=0 from your custom x264 settings.

You are still usin OpenGL
14:45:05.209: Warning: The OpenGL renderer is currently in use. On windows, the OpenGL renderer can decrease capture performance due to the lack of specific features used to maximize capture performance. The Direct3D 11 renderer is recommended instead.
Advanced settings, change renderer to Direct3D 11

In your scene
18:07:10.433: - source: 'cs:go' (game_capture)
18:07:10.433: - source: 'H1Z1' (game_capture)
18:07:10.433: - source: 'infestation' (game_capture)
18:07:10.433: - source: 'OVERWATCH' (game_capture)
18:07:10.433: - source: 'dead by' (game_capture)
General advise is having only one game capture per scene collection.
So, unless your game captures are each one specific for each game, havign more than one gaem capture can produce problems
For instance, with H1Z1 there are several attempts to hook it.
Same with overwatch
So, try using only one game capture.
Also, don´t use 2 pass encoding for streaming.
