.stutter

Hey guys, i have the following problem: if i start OBS everything is fine (framerates in LoL are 120- 144Hz) all good. if i start the stream however the frames go all over the place. I googled a lot the last copuple of days and searched for the reason of this issue... the log told me then that...

Look at my logs here https://hastebin.com/qobomifugi When i try to record my game's fps are really bad and csgo starts to stutter and skip frames. Any ideas?
