Easy way to workout Frame Rate FramePerSec

The simplest way to set a certain framerate would be to use a timer, for example

Graphics3D 1024,768,16,1
Setbuffer BackBuffer()

Timer_Frame = CreateTimer(30)

Camera = CreateCamera()

While Not Keyhit(1)

WaitTimer(Timer_Frame)

UpdateWorld
RenderWorld

Flip

Wend
End

I think this is the simplest way but there are much better ways of achieving a set framerate and I wouldnt recommend using this in a game.
