Hi Daniel, The biggest benefit I know of is loading large databases. On a 32-bit processor you get up to 4GB of address space. On win32 you get 2GB max, or 3GB by hacking something in.
With a 64-bit build of osg, you can address up to 1000GB of address space. In conclusion, if you don't have more than 2GB of RAM, don't bother with 64-bit. If you want to avoid paging large databases, step up to 64-bit, and jam the ram into your system. If the databases you load up, are all less than 2GB in RAM, then don't worry about 64-bit. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Daniel Holz Sent: Thursday, November 29, 2007 10:38 AM To: OpenSceneGraph Users Subject: Re: [osg-users] 64-bit OSG hi, what are the benefits of using a 64bit build of osg. as far as i know at least the floating point precision is not higher than with 32bit, or am i wrong? cheers, daniel Robert Osfield wrote: > Hi Robert, > > The OSG support 64 bit builds on Irix, Solaris, Linux, and even > Windows..
