If you have source with low frame rate (24-30 fps) then SVP must work and give you desired framerate at output. Output frame rate must be equal to display refresh rate.
But if you have source with high framerate (50-60 fps) then you need to encrease value of setting frc.tarfet.max in all settings window (Application settings - Additional options - All settings...)
The default value is 47. Change it to 61 or more.
