Radeon host application makes games and windows video player run poorly when in fullscreen, but not windowed

Videos originally recorded at 60fps, when viewed on the windows video player seems to be 15-30fps. 
The game cities skylines runs poorly unless I end Radeon host task with task manager, but then it opens itself a second after and the frames go lower again. I can, however stop this problem by running the game windowed. same with windows video player. the performance is also normal if i press the windows button while watching a video or playing cities.

 

the thing is, I want to play fullscreen with normal performance and the only way is to not have radeon host service running, otherwise my fps is super low. (this shouldn't happen anyways, with a ryzen 5 3600, and rx 5700 xt.)

 

here is a video of cities skylines running poorly in fullscreen but smooth when windowed or after pressing windows button https://imgur.com/AlOWku4
