JamesTaylor Posted October 16, 2007 Share Posted October 16, 2007 So how many of you out there have made the change to 64bit computing, most specifically, but not exculsively, with max / viz and vray?? How did you find the switch over? What problems have you encountered along the way? How much RAM are you now running for use with your renderings and how are you finding the having the additional resource available when considering the volume of information your putting in scenes?? Have you noticed any speed increases... or decreases for that matter! Do you believe it is yet safe to take the plunge and move from 32 to 64 bit systems or are there still too many issues to be ironed out currently?? your views please!!

andreg Posted October 16, 2007 Share Posted October 16, 2007 I have been working with a mixture of 64 and 32 bits... depending on the situation. 64bit bascially just allows for more complex scene with millions of polys and tons of ies lights without crashing. The only anoying thing is the damn v-ray spawners, you can't have them both (32 and 64 bits) running at once on the same machine (64bit machines). But my final advice is, 64bit is the way to go for enormous scenes. If you don't need the extra RAM then stick with 32. Speedwise... it's about the same Link to comment Share on other sites More sharing options...
visual3d Posted October 16, 2007 Share Posted October 16, 2007 Well ive been using it ever since it was out. we had some minor setback because most of the drivers for previous hardware before 64 came was unavailable. But after using it for almost a few years now...its great especially on new systems where drivers are design to work with 64.. You will notice about 30% speed increase if youre using an all 64 system...which means you use xp 64, a 64bit 3d software and plugins that is also 64bit coded. How ever you can still run about 90% of application out there under 32 bit enviorement. Most people dont understand that a software must be design to work with 64 and multiple cpu cores. most softwares and games are still running single core which makes the system slower than 32 bit but with higer clock...cause most dual or quad core have slower clock timing than single core..

JamesTaylor Posted October 18, 2007 Author Share Posted October 18, 2007 thanks for the replys guys, i think we'll be going 64 bit sooner rather than later so just trying to get the heads up. Have to say i'm looking forward to possibilty of scene sizes on 64 bit i like to throw as much at the renderer as possible and on 32 bit it usually starts flake at some point!! a 30% speed increase would be an awesome benefit to boot! Andre are you using a mixture of 32 and 64 bit stuff all thro a 64bit platform or are you still reverting to 32 bit system aswell? i think i read a while back that 32bit apps would run better on 64bit due to the fact that 64bit systems would have enough RAM available to assign the maximum applicable to each 32 bit app??

JamesTaylor Posted October 18, 2007 Author Share Posted October 18, 2007 Also, what operating system are you using? is it Vista 64bit or the 64Bit XP version?? Our IT guys still won't recommend Vista for office use yet even tho its been out the best part of a year....?? Link to comment Share on other sites More sharing options...
andreg Posted October 18, 2007 Share Posted October 18, 2007 I run xp pro64, I don't trust vista yet;) Like I mentionned before, I use the 64bit systems for extreme cases since we have 4 64bit machines and 2 32bit machines. So in order to use all the ressources available, I use 32bit to have all 6 computers working at once when RAM doesn't become an issue. When my scenes are crashing on the 32bit systems, I switch to 64 and use only 4 computers. Soon enough we'll replace the 32bit machines for 64bit to use exclusively 64bit Link to comment Share on other sites More sharing options...
Crazy Homeless Guy Posted October 18, 2007 Share Posted October 18, 2007 i use a 64 bit system running XP64, however, i do run a 32 bit version of Max. i still see an advantage of doing it this way because i can access all of my ram. ...like everyone is saying, don't go Vista until at least service pack 1. i am running Vista at home succefully, but nVidia still has a lot of work to do on their drivers.

Raffaello.S. Posted November 19, 2007 Share Posted November 19, 2007 is it possible to have a 64bit workstation and 32bit render slaves?.. Link to comment Share on other sites More sharing options...
WAcky Posted November 20, 2007 Share Posted November 20, 2007 I have to disagree with the recommendations against Vista. Vista handles memory much better than XP does. You just have to make sure you don't let vista waste it all on its over-the-top default display settings. I just purchased a Q6600 quad with 4gb of ram. I decided to go with Vista ultimate 64. Set the display settings to look like win98 and its a dream. after startup i forget im using vista. I have had zero problems so far. Totally stable so far. Im 100% satisfied with my 64bit machine.

dagor Posted November 20, 2007 Share Posted November 20, 2007 i agree with James there was similar situation when we move from win2k to XP. all said xp waste memory and it realy heavy for resources. but it`s inevitable, we going to vista anyway. hardwaere become more productive and efficient so vista will be ok very very soon.

JamesTaylor Posted November 20, 2007 Author Share Posted November 20, 2007 does anyone know if there will be a 64bit version of Viz compiled or is only going to be Max that goes 64bit? Link to comment Share on other sites More sharing options...
mesht Posted November 22, 2007 Share Posted November 22, 2007 i've actually asked that question to my local vendors, they told me viz would not be going 64bit, even the viz2008 does not recognise all four cores on my dual-core machine. so i'm forced to upgrade to max 9 in the end, to fully utilized my processors.

Iain Denby Posted November 22, 2007 Share Posted November 22, 2007 yeah, I'm doing the same. I'm going from Viz 6 to Max 2008. Link to comment Share on other sites More sharing options...

mesht Posted November 23, 2007 Share Posted November 23, 2007 viz2007 still support multicores, but not 2008, that's what i'm told. i did few tests and it shows only two threads, even with the "multi-threading" option is ticked. checked with some viz08 users, they too claimed viz08 does not utilized all cores.

JamesTaylor Posted November 23, 2007 Author Share Posted November 23, 2007 well that sucks! were waiting for sp1 to come out before upgrading, that plan may have to be shelved now! time to do some further research Link to comment Share on other sites More sharing options...
