[solved] fullscreen problem

Hiya, i got a problem with the fullscreen mode.

When I set to a fixed frame (of 16ticks or more == 60 fps or less) on fullscreen it seems bugged the render of it. the lines of the scenario distort a lot when i walk with the camera

and when i don't set the tick and use the default, the lines don't distort but it is a slow fps

here is how my settings are set:

<?xml version="1.0" encoding="utf-8" standalone="yes" ?>
<TorqueEngineSettings>
  <SimulateFences>false</SimulateFences>
	<UseFixedTimeStep>true</UseFixedTimeStep>
  <TickMS>16</TickMS>
	<UseInterpolation>false</UseInterpolation>
	<EnableAudio>true</EnableAudio>
	<GraphicsClearSettings>
		<ClearColor valueOf="Microsoft.Xna.Framework.Graphics.Color.Black"/>
	</GraphicsClearSettings>
	<WindowsGraphicsManagerSettings>
    <IsFullScreen>true</IsFullScreen>
		<PreferMultiSampling>false</PreferMultiSampling>
		<PreferredBackBufferHeight>900</PreferredBackBufferHeight>
		<PreferredBackBufferWidth>1440</PreferredBackBufferWidth>
	</WindowsGraphicsManagerSettings>
	<XboxGraphicsManagerSettings>
		<PreferMultiSampling>false</PreferMultiSampling>
		<UseDisplaySizeForBackbuffer>false</UseDisplaySizeForBackbuffer>
	</XboxGraphicsManagerSettings>
</TorqueEngineSettings>

i dunno how can i fix this problem, any idea?

thanks in advance


EDIT
Solved using interpolatetick instead of processtick
