Unstable framerate in the D3D application

[ASD]

Unstable framerate of the D3D application.
It's going horizontal scrolling with V-Sync enabled by command line.
And this application launched by launcher application with Standard runtime application (with change resolution).

What's the workaround of this problem?

I had two question.

1, Does not work the /VSYNC command?
2, Application will be slow when run application with V-Sync was enabled(by propery of MMF2) and changed resolution to 640x480 by other program or EXE property.
