Hevc jerky in windows but totally fine in openelec

Hi,
I wanted to move from openelec that i used for a long time to windows 10, i have a low end NUC with intel n2810 and 2gb ram.
So same hardware same video file same everything, in openelec 720p hevc plays perfectly fine, but in windows 10 its unsmooth video and audio is unsync with video. I tried to change advancedsettings.xml cache, it might helpd a little but still when the scene is fast the audio is comletly out of sync with video, tried with/without passthro, didnt notice a change.
In openelec i had kodi 15.2 and in windows kodi 17, so tried 15.2 in winsows – was exacly the same.

I also played the same video file in my old i3 laptop with windows 10 and there it was smooth and nice.

So how can i (try to) fix the playback in windows 10 in the nuc?

Thanks
