What hardware ?

Your going to need 64bit for those file sizes.... 32bit can only handle
under 4gb or is it just over 2gb..

How many verts/tris ? I imagine a quite lot with a 70mb file

thats one heck of a lot of data to load and would take some time, you would
probably best of converting to a PFB file as that would sped loading up

Your going to have to suck it and see I would guess, it’s the only way you
will see if it works

Best Regards

Subject: [info-performer] Large CADx file laoding

Hello All,

We are exploring the possibility of  using Performer to do visualization of
very large CAx models.  The probable PFB file size can be  70 GB.   We
need to load the whole file into the memory and achieve 25 Frames/Sec.

I guess that some of the issues could be loading time for such large file,
I/O bandwidth of hardware , RAM size ( RAM allocation in Performer), use of
multi graphics pipes.   

Is there any limitation on the file size that can be loaded into Performer?
 

What could be other technical challenges?

I appreciate if any body can share their experiences with handling such
large file sizes in Performer.    

Thanks
mandava
