Kodi 17 on aced revo 3610

Hi all,
I recently upgraded my kodibuntu from 15 to 17 on my acer 3610 which has a SSD and 4 gb of ram. It connects over a wired connection. On the previous version of Kodi it worked fine.
But now when I play videos, they buffer. I’ve tried enabling hardware acceleration, but it still buffers.
Does anyone have any suggestions I can use to remove the buffering? Or is the box just to old?

Thanks
