Just upgraded my RAM from 2 GB to 4 GB. Is there anyone here who can tell me in plain English how to activate "4-gigabyte tuning" for XP Pro? All the information I can find is tech-speak meant strictly for programmers and developers...of which I am neither.

Ok. I found out how to set the /3GB Switch here:

http://softimage.wiki.avid.com/index.php/How_To:Set_the/3GB_Switch

The question I now have is, "Can Vue 6Inf take advantage of the extra gig of memory that I've just freed up, or do I have to do something more?"

Well, evidently it can, because I just loaded Vue and found an 18% increase in current system resources just by setting the switch. 

I'm happy now.

:)

Actually Vue does NOT support more than 2 Gb ram.  With the /3Gb switch your system will allocate 1 Gb for the OS and the other 3 Gb is reserved for those programs which are "aware" (ie photoshop).  For more information:

You're probably seeing an increase in your system resources because Vue is now utilizing 2 Gb. 

So which are you saying? You CAN use the "LARGEADDRESSAWARE" hack to make Vue see 3 gigs or you can't?

Ok. I hate to contradict you, but I now have the computer set up with a dual boot. One boot with the /3bg switch on, and one with it off.

When I boot with the switch off and load Vue, it gives me a resource level of 83%. When I boot with the switch on and load Vue, it gives me a resource level of 94%...an 11% increase just by booting with the switch on! So, there is a benefit, even if Vue is not actually seeing the 3rd gig.

Well, I don't know why the increase in resources from the 3 gb switch, but you're correct, Vue is NOT "LARGEADDRESSAWARE". I found that out by using a program called, LaaTiDo which was created to give end users a safe easy way to turn on "LARGEADDRESSAWARE" for just about any program. (and turn it off again if need be)

I turned the function on for both Vue 6 Infintie.exe and Vue 6 Infintie.eon without any problems, but I honestly don't know if that did the trick.

Correct.  Vue is not "LARGEADDRESSAWARE".  You can add LARGEADDRESSAWARE to the header in Vue 6.exe and Vue 6 eon using the free version of Microsoft's Visual Studio.  I've also applied it to Poser 7.  Like smallspace, I also have my system set for dual boot, one using the /3gb switch and one without.   Without using the "LARGEADDRESSAWARE" tag, when you boot up using the /3Gb switch, you have a full 2 Gb ram allocated to Vue.  If you boot up not using the switch there will be LESS than 2 Gb ram available for Vue (because more than 1 Gb is reserved for the OS), which is why you're noticing a difference in system resourses.  But if you add the LARGEADDRESSAWARE tag AND the /3Gb switch you'll have 3Gb available for Vue.  In all honesty there are very few instances when Vue will ever attempt to use more than 2Gb, but your system resourses will be higher as your system is using a smaller percentage of the Ram available to Vue.  I have not tried "LaaTiDo", but I'm certainly going to take a look at it. 

As a test, I booted up using the /3Gb switch after applying the "LARGEADDRESSAWARE"  tag to the headers and loaded up Vue with as many large objects, ecosystems, etc. as I could, watching peak memory useage in task manager, and I "finally" got Vue to use almost 2.5 Gb Ram and it was still stable.  Again, I don't know if, under normal circumstances, you'd ever need more than 2Gb, but it can be done.   

Smallspace:  Thanks for the link to LaaTiDo, it works flawlessly (and a heck of a lot easier than installing Microsoft Visual Studio to do the same thing :o).  Much appreciated.
