Kodi 17 playback choppy sometimes

Hello,

after upgrading to kodi version 17 and 17.1 sometimes when I an playing video from hard disk (not using streaming often) the video is choppy. The problem does not appear on version 16 or lower. After searching around I believe the problem is that version 17 is much heavier than previous versions of Kodi but I am not sure. My hardware/software is the following:

CPU: Intel i3 2100T
RAM: 4GB (2 x 2GB)
HDD:128 GB SSD drive
GPU: ATI Radeon™ HD 5450 Graphics
OS: Windows 7 64-bit

Can someone confirm/deny whether my hardware is enough to run Kodi 17?

Also can someone provide support to fix my problem if my hard is enough?

Thanks

Phanos
