Lighting not showing in viewport

[eliaschamba]

Please help.I am using Vray 3.0 for rendering 3dsmax 2015.When i change settings for scene lights,It does not show in the viewport despite switching to realistic mode.However ,when i render the image,the differences show in the rendered image.

 

Even if i change the intensity multplier value it doesnt show in the viewport but it shows in the rendered image.Thank you in advance for your help.

I've never used the Viewport to determine lighting as I am sure it is not a very accurate solution, but if that 's what you want to do then this should be how to do it:

 

Hit Alt+B and switch to "Scene Lights": in the viewport. Also make sue that "Viewport Shading" is enabled in the lights parameters.

Thank you but i had already done this when i posted about the problem without any success.I am using a 4gb ram dual core lenovo g50...could the computer specs be the cause?
