Rhino & V-ray work on 64 bit?

[Paraglobal]

Hi all

A customer of mine asked me about Rhino & V-ray working in 64 bit so that he can put more ram that 2 GB and maybe speed ut V-ray.

Can someone explain to me what is the situation status here and is it worth it? will rhino/V-ray work faster?

Thanks
Sergio

... and my question to the subject: make it sense to use more than 2GB RAM yet?

I believe Rhino is a 32 bit application only. But 64bit windows will run 32 bit apps natively. I'm not sure if that means the 32bit apps will have access to the expanded memory or not - maybe an operating system buff out there knows? If not I'll see if I can track down the answer to that.

We have machines that use the 3gig switch for XP and that does supply more memory - I'm not sure if that answers your question

Hi joeb

Could you elaborate on the 3gig switch bit? - Sounds useful!!

copy-pasted from the Vray forum:

In order to help our users, here is how the 3GB switch can be setup.
This has been discussed a lot in the forum, though there are still users finding problems with it.

First, an additional line has to be added in the < boot.ini > file.

The < boot.ini > file is actually a protected system file, which is
hidden from the Windows OS by default. To make it accessible:

• (*) Open the Explorer ;
  (*) Tools - Folder Option ;
  (*) View - Tab ;
  (*) Uncheck the < Hide protected operating system files > ;
  (*) Look for the < boot.ini > in the C:\ root folder ;
  (*) Open it using Notepad.exe (or any other editing application) ;
  (*) Copy the last line, which ends with "... /fastdetect" ;
  (*) Paste it in a new line and replace that with "... /3GB" ;
  (*) You may want to add some text between the brackets, to know which Windows is the one with the 3GB ;

Here is a typical < boot.ini > and how it looks like:

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINXP
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINXP="Microsoft Windows XP Professional" /fastdetect
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional 3GB" /3GB

Important:

There are some CPU and MB configurations, which also do not allow this extension to run properly.
If you have encountered this, please report the hardware specifications.
Thank you !

Was VRay compiled with support for the /3Gb switch ?
