Use the PerformanceGoal option.
Manipulate[
ContourPlot[
a x^2 + 2 b x y + c y^2 + 2 d x + 2 f y + g == 0 /. {a -> 1, c -> 3,
d -> 0, f -> 0, g -> -1} // Evaluate, {x, -5, 5}, {y, -5, 5},
PerformanceGoal -> "Quality",
PlotPoints -> 10],
{{b, 0}, -5, 5}]

Dear all,
The following produces a smooth function. But when I hold and move the
slider the function appears jagged and is only fully drawn when I
release the slider.
I know this is done to show an initial result very fast. Is there a
method to influence this behavior?
Manipulate[
ContourPlot[
a x^2 + 2 b x y + c y^2 + 2 d x + 2 f y + g == 0 /. {a -> 1,
c -> 3, d -> 0, f -> 0, g -> -1} // Evaluate, {x, -5,
5}, {y, -5, 5}, PlotPoints -> 10], {{b, 0}, -5, 5}]
Thanks for your help,
Maarten
