Try to enable/disable Vsync in ... driver's control application (I assume you
use proprietary drivers with Nvidia GTX-750ti)
And also same in window manager settings.
Try to set CPU and GPU to maximum performance (I think I observed some

These are Proxys in mpeg with the same characteristics as those I had
tested with DNxHD media.
