Help Help Help !!!!!!!

Can anyone help, recently bought a Q android box as my old MXQ box couldn’t take Kodi 17. Never had any problems with Jarvis, but now I can’t seem to play anything without picture stutter/frame drop. I’ve tried just about everything, acceleration on and off, sync playback on and off, refresh on, off and stop start, fps set to 24 in box settings, nothing seems to work. Can any body recommend the optimum settings for smooth playbackConfusedConfused

Thanks in advance
