in one scene you trying to hook into 2 different sources on a single scene this can cause trouble
- 18:10:47: Trying to hook process: LolClient.exe
- 18:10:47: Trying to hook process: League of Legends.exe
also your bitrate is pretty high.
consider downscaling your resolution if you want to stream with 60fps (1280x720 should be the best)
make sure that you try to use game capture only you might also consider disabling aero if you are not using window capture for anything fancy.
as for testing i would delete ALL scenes creat 2 scenes 1 can be a simple monitor capture (with aero disabled) to capture your lol launcher .... lol launcher has changed there have been quite different ways maybe you can game capture it by now.
as the 2nd scene you creat all you use there as source is the game capture of the game itself and then see how the performances varies
also make sure to restart your obs after doing those changes so the log has a clear end and not 1000000000 changes in one log :)
