I just discovered this and i need to see if it's a known issue or how to fix.
After using PinballX to launch Visual Pinball X, i noticed that some tables had microstutters that there weren't there before. Like, subtle repeated frames ever 20 seconds or so. You may or may not notice this, it depends on how sensitive you are with this. But it's there, and here's the proof:
The first half of the graph is two tables played in Visual Pinball X, without the PinballX frontend in the background. You can see that the lines are perfectly flat.
The other half is the same tables but this time i launched them via PinballX. You can see the lines are not the same, Every about 20 seconds i lose a frame, which looks like a noticeable stutter.
This is very bad since i need PinballX to run a pincab. Is this known? Can it be fixed?
