<r>Just checking... I downloaded the windows 6.2 installer and selected 64 bit in the installation dialog. Has that now installed 64 bit version and will it load 64 bit java?<br/>
<br/>
I seem to recall with an earlier version it wasn't so simple as that but maybe the world has moved on while I wasn ...

<t>I guess using the GPU is not going to happen, I can see why. Unless of course someone else writes a photo renderer you can use which does that - seems to me in my limited understanding that modern graphics cards are more or less a dedicated additional computer whose only task is graphics ...

as for sending the file it's a bit big... about 31MB.

<t>Well... win 7 x64 installed, so now it uses all the memory, and java x64 plus your sweethome .jar, and now (finally) task manager reports java using something near 1.5gb rather than 650mb. The scene it's rendering is still not *fast* exactly, but there is visible progress, which is more than it ...

Everything so far has exactly the same result, none at all, that is. Task manager still reports the java process using the same amount of ram and the rendering process is so slow as to be more or less unusable I guess I'll just have to not make such large projects.

<t>ah ok. I'll put it back and see what happens. Been looking into things like PAE but although the CPU supports it and it's supposedly enabled, don't seem to make any difference. I really don't, at this point, want to install win7 x64, I suspect I'll have too many compatibility issues. I imagine ...

I also found this http://www.wikihow.com/Increase-Java-Me ... -Windows-7 while searching for info, which I will try.

yeah I saw that typo just now... Just went off getting latest java, in case it was an old one. I'll see what happens next. There is of course the thing where 32 bit windows will only use about 3.3GB memory, however, task manager shows only about 1.96GB used.

<r>Does the .ini file just contain that -Xmx1024m (or other amount), nothing else? After being infuriated by windows' safeguards that won't let me save in the program files directory, I saved the file (text file) in another directory and copied it into program files/SweetHome3D which is the location ...
