if it works fine in MPC-BE then it must be someting in DS, although i've had similar issues myself int he past. 

 Thanks but none of that worked :/ My GPU is 970 but my CPU decodes the video for me(4690k).

It's really strange how DSPlayer was working fine for months, I even watched a 4K remux just last week without a single stutter.

But now all of a sudden they playback in slow-mo.
