Playing Smoothly but randomly after a bit it gets Choppy

[Blackcan]

Hey i got SNES9x 1.6 Today and set it up and Installed a SMW 1 Hack.
And usually it plays really smooth with almost no input lag, but sometimes it just feels like that there are missing frames or something since it doesn't look smoothly but my Framerate is still at 60.

There are my Settings:
Output: Direct3D
Integer Scaling
Reduce Input Lag
Automatic Skip at most: 0

No Tripple buffering and no V Synch

My System:

16gb DDR4 Ram
GTX 1060
AMD Ryzen 2700x

Thanks in Advance!

Try enabling the DWMSync setting within the emulators configuration file and then retest your games.
