Hello, I am running Rhino5 64 Bit.
I have a 137mb .3dm file that is very laggy in the viewport when certain layers are on. Obviously, these layers are the ones with the most data in them, but there aren’t any complex surfaces, just basic planes, and some curved surfaces.
I would understand that a computer with low specs could lag because it doesn’t have the required performance to handle the file. My gripe with Rhino is that, even though I have a very good system (that my firm paid a lot of money for), it doesn’t seem to make a difference in the viewport performance. In fact, I opened the same file on another, lower-spec computer, and got pretty much the same results (similar FPS). What’s even weirder is that, if I increase the OpenGL appearance settings, there is still barely any difference, because my graphics card can handle the 8x anti-aliasing with ease. But there is not much difference in FPS.
This leads me to believe this is a software problem. If you watch my video, you can see that my RAM and GPU is barely being used, even though I have a lot of excess resources available. I am OK with Rhino using more RAM and increasing GPU usage, even up to %100, if it means I can get better FPS in the viewport. But it doesn’t seem to want to do it. I don’t know if I’m doing something wrong, or if I’m correct in my assumption that this has to do with Rhino itself.
I would appreciate any comments on the matter.
