Premiere Pro doesnt show my effects, Masks, adjustment layers when its not rendered

Okay so I have a Smooth playback when I'm in premiere pro and a graphic card that handles all of the normal playback problems pretty well but I have this problem where premiere pro doesn't show my effects when it is not pre-rendered. I've searched the whole internet for this and couldn't find a solution. It's Almost Impossible to work like this because I have to pre-render everything after I applied an effect, just to see if it looks good. Please help me, thanks! Best regards Moritz
