I was having this issue with a pre 1.0 build and updated last night to the latest version of SR to find the issue is still there. I'm using Max 2012 x64 PU
My issue is that the 'medium' quality preset gives me reflections of my hdri domelight (with a vrayhdri tex) yet any preset above medium kills these reflections. I've tried various settings on and off but can't find a solution. I have no idea whether it's a glass material issue, or an issue with the HDRI. I think it could be the HDRI as the glass still seems to reflect the rest of the scene.
I have attached the two examples plus the solid rocks setup.
