    private void PreparingDeviceSettings(object sender, PreparingDeviceSettingsEventArgs e)
    {
        nativeScreenWidth = graphics.PreferredBackBufferWidth;
        nativeScreenHeight = graphics.PreferredBackBufferHeight;

        graphics.PreferMultiSampling = true;
        graphics.SynchronizeWithVerticalRetrace = true;
        graphics.GraphicsProfile = GraphicsProfile.HiDef;
        graphics.PreferredDepthStencilFormat = DepthFormat.Depth24Stencil8;
        e.GraphicsDeviceInformation.PresentationParameters.MultiSampleCount = 8;
    }
