Hi,
here are the log.txt and the PinballX.ini to check.
And here is a link to a short video of the start of the VPX-table (4 MB) "Rolling Stones".
Normal start 2 seconds from double-click, start in PinballX around 40 seconds.
I have the normal Win10-Codecs and install addtional the VLC. That's all
As media-types: png, jpg, f4v.
As I see in the log.txt, it takes 34 seconds between opening the vpx-table to start vpauto.exe!
