I'm still really new to C4D and struggling with a project which has reflections, glass transparency and GI.
I rendered as a test at 720p which took 40 hours to render over the weekend but the HD 1080p version is taking almost an hour per frame...
I'm not sure if my render settings are correct for the project or if this kind of thing just takes this long and I need to sacrifice something.
I've attached my project file and a screenshot of the final render.

I did a few tests here. Frame 582 (because that's where the file you sent is sitting, it doesn't match your render example, not that that matters) takes:
- 4:01 to render 1920x1080 as is GI with GI Samples set to Med
- 1:09 to render with no GI (but looks significantly different)
- 2:42 to render with GI with GI Samples set to Low with no real difference to the look
- 2:10 to render with GI with GI Samples Low and Discrete Area Sampling and Discrete Sky Sampling turned off
all of those times without bitmapbw.jpg which it asks about every render but that's bump in the glass so the numbers should hold, so it looks like you can almost half your render times by changing your GI settings.
