With certain Visual Pinball 9.21 tables I notice a decrease in performance between running a table directly from VP, and running a table from PinballX. The ball doesn't run as smoothly. I'm using PinballX 1.87 with two monitors: one for the FS playfield and one for the backglass. In the menu I'm using a video preview for both. When I replace the backglass video with a backglass image and start up a VP table, there's no performance decrease. Has anybody else noticed this?
