Guest EricFoy Posted September 11, 2007 Share Posted September 11, 2007 Here's a picture of my task manager during rendering of a BIG picture. This machine seems always to have performed very poorly running IronCAD. I have installed 4GB of RAM. I think the fourth gigabyte is a waste, since Winblows seems to have no notion of its existence. Anyway, I have set the /3GB switch, and no matter what, the task manager NEVER reports that the machine is really using any RAM to speak of. This rendering is taking like 30 minutes! Way too slow in my experience. I think this machine just sort of bites, performance-wise, but I can't figure out how to light a fire under its butt. I've tried a dozen different pagefile settings, to no avail... Suggestions, anyone?

Cary OConnor Posted September 11, 2007 Share Posted September 11, 2007 First question would be what does the scene look like that you are rendering (what geometry is contained in the file). Second, I don't have much experience on Windows XP Media...You may need to bump up to XP Pro. Cary Quote Link to comment Share on other sites More sharing options...
Mike Twining Posted September 11, 2007 Share Posted September 11, 2007 (edited) All of your analysis is correct. 1) Your problem is XP Media Center... it being the Win98 of the newest releases: it won't benefit from the added memory because 2) the /3gb switch does nothing to this version of windows. You need XP (Pro). You are basically driving a Ferari there, but is has an Fiat engine in it. Spring for the extra $200 and get your V12 back! EDIT: Well, upon further research, it appears as if Microsoft is inconsistent in determining which OS's will accept (succesfully) the /3GB switch. Some of their pages imply XP Pro only (for the XP family anyway) and some say all versions of XP (whcih would include Media Center). Personally, I am still inclined to believe that it is XP Pro only....but I am no longer as sure.

Jonas@Solidmakarna Posted September 11, 2007 Share Posted September 11, 2007 This page maybe can sort things out? http://msdn2.microsoft.com/en-us/library/ms791558.aspx Quote Link to comment Share on other sites More sharing options...
IronKevin Posted September 11, 2007 Share Posted September 11, 2007 If you are doing Realistic Rendering the CPU will be pegged but RAM is not as involved and it's usage most likely will remain at a fixed level. Quote Link to comment Share on other sites More sharing options...
