Hi,

I can not figure out why :
ParametricPlot[{Cos[t], Sin[t]}, {t, 0, 2000}, AspectRatio -> Automatic];
is far from plotting a circle.

For sure it is precision problem in sin.cos evaluation but I can find a way to force ParametricPlot to perform the computations with the needed precision.

For instance,
ListPlot[Table[{Cos[t/100], Sin[t/100]}, {t, 0, 200000}], AspectRatio -> Automatic]
works well but I would like to find a solution using ParametricPlot.
