I just bought Rhino 5 + V-ray 1.5, installed a 64-bit versions. I have difficulties with opening an older scene, made in previous versions (R4 + Vray1), it takes ages to process. Once open, any simplest command like select or zoom takes incredibly long time to process. Meanwhile in the top left corner there is written “program is not responding”, it is completely frozen. It is just impossible to work with this, I usually have to end the program via task manager, because closing normally is impossible as well.
I think the problem might be the video card. I have Nvidia Quadro 600.
Today i managed to open another older scenes, which were not so hard to move in, yet the zooming was not smooth enough. So I can tell some files are stucked totally, some more and some less, depending on how much object there are. I reinstalled everything and when I had only Rhino (without V-ray), zooming and processing was difficult and slow, when I added V-ray, it got worse.
