SVP/MadVR acting weird while using Potplayer

As you can ses the red cirled line is my framerate which should be on 71.928, but its jumping to 70, 69, 75 everywhere, and won't stand on 72Hz alone, which reason could this be?
As for the blue circled line, it goes slowly up, like you can see on the picture as of this time of the video, its already on 100frames, even if I pause the video it still goes up, its already on 230. What the heck?

Does anyone have a solution to this? if so I would greatly appreciate it, if you'd shared it with me! ^^
Thanks
