I have the same problem ...http://sketchucation.com/forums/viewtopic.php?f=322&t=53929

One problem (as shown in 2.jpg) have eliminated by changing Material - Reflection - Glossiness - Treat glossy as GI of Allways the GI rays only and increasing subdivs as written reymond and dkendig.

The problem (as shown in 1.jpg) is likely to eliminate possible options Material - Reflection - Glossiness - Hilight and Reflect.

Still unfortunately undulating reflections appear (shown in 3.jpg) and do not know how to get rid of them. They appear most often on the walls next to the items that reflect.

I'm sorry, I'm a beginner. How to set it up?

None of this I do not understand ... I put it anywhere else light source?

I understand that after I finished render save the file as a .png or .tif? Unfortunately, on the same ....

No, because the render also it shows

My model weighs too much. I threw VRay settings - during the day and at night.
