Maybe it can help someone somewhere about performance.
For a long time on some table (the one i got it most prominently was "24" ) when using VPX i had some bizarre "visual lag" when the ball was hitting some bumper.
When it happened, the video seemed to freeze for half a second but the ball was apparently still moving even if not showed as once the freeze disappeared the ball was where it should have been without the freeze.
Was very annoying to me as even when lowering every option it still happened. So i thought it was one of those VBS issue with window 10 own defender.
I also noticed that while i was halving the resolution of every textures files used, that visual lag was lowered.
I finally found out what was the source of the problem : "Texture Compression" , as in games that featured this option it was always a good one to improve performance, i had this enabled all the time when using VPX.
For some reason after testing with it disabled, no more "visual lag", even when playing the version of the table that had its texture at full size.
So in case you run into similar problem, check if you have "Texture Compression" enabled, if so disable it.
Interestingly i had a similar problem with "Texture Compression" enabled with Future Pinball , though unlike VPX it was not a visual lag, but some noticable slowdown on some busy tables.
