VERY slow video rendering
I made the first part of a "simple" house in SH3D with a bigger library than it is used to be in the free version.
I just created a living room(File Size: 15 MB) with around 80 things. It has 13 lights in it and I just used a plant, so there should be any problem.

Photo rendering in FHD(1920 x 1080) in best quality mode takes around a minute on my pc(for specs see below), and then I wanted to make a short video.

First of all, it took around one hour to compute, that the rendering
would take...180 days. shock
I don't wanted to wait so long for a 30-second-video in FHD. So I went on Google and found the hint about the SweetHome3D.lvj.ini file with -Xmx1024m. I tried it with 1G, 2G and 4G, but nothing changed on the rendering time of a picture.
I tried the video with 4G, it just still says 175 days. sad In photo rendering mode, it doesn't uses all the time(also without the file) more than 1,5G RAM. My CPU is all used up, while rendering, but that's in Blender too.

Also I tried to use the Advanced Rendering Plugin(is someone developing it anymore or did I miss something?), but it doesn't installs(I open it with SH3D and it shows the dialogue, which says, that it's installed, but there aren't any changes in the Photo Render Dialogue, even after a restart).

Also I changed SH3D to highest priority in Task Manager, but that doesn't speeds up rendering time.

PC Specs:
CPU: 4th Gen i5(4 x 3.20 GHz, overclocked to max 3.50 GHz)
RAM: 8 GB(Windows uses around 3 GB)
GPU: nVidia GeForce GTX 750 Ti(2 GB GRAM)

How can I speed up rendering without loosing quality(lower resolution, worse quality, fewer lights)?
