Re: 3d View suddenly impossibly slow
Detecting the machine specs is too complicated: it depends on the version of the system and of the graphics drivers, and before all, I don't have the means to test all the possible combinations. Anyway, from version 6.0, selecting the 32 bit architecture option in the installer just installs Sweet Home 3D with the same command line options you cited, and this choice is the default selected one under Windows 10 64 bit.

Re: 3d View suddenly impossibly slow
Same problem here, although i'm using Win 7, 32 bit. Always worked like a charm. Just started using the program again after a long time. Updated to the latest version and the program becomes jumpy and then soon impossibly slow. I thought the problem is with my modest hardware, and somewhat complex model (using the editor to make custom "brick" units cobbled together into see through wall portions). But it seems more people have experienced the same lately.

Re: 3d View suddenly impossibly slow
Try an older version like 4.6 which used another version of Java and Java 3D. If you see no difference, it's probably not an issue in Sweet Home 3D.

Re: 3d View suddenly impossibly slow
I tried it. Works a little better, but still much slower than i remember. All the more complex elements were blacked out though, on account of missing functionality between the versions i suppose. The newer version is just bearable with all that "fluff "made invisible. It seems there's a very fine margin between somewhat slow and impossible slow, at my end. I tried some for the solutions mentioned through the topic, but so far no luck. Perhaps it's a sign i need a newer PC, but seeing other people suffering the same is intriguing.

Re: 3d View suddenly impossibly slow
I had this issue in Windows 10 64 bit and two things seemed to improve it. I switched to the app store version of the program and performance improved slightly. I increased my computer memory (DRAM) from 8gb to 32gb and that vastly improved things. I noticed the issue was more pronounced with textures (specifically floor, and likely ceiling and wall although my file doesn't have those). Disabling textures improved performance. I think increasing DRAM must have helped load the textures.

Re: 3d View suddenly impossibly slow
Hello,
The issue has been fixed on my side by installing the plugins "AdvancedSettings_PhotoRendering-1.3.1.sh3p" and "PhotoVideoRendering-1.8.zip". You can find them here: "http://www.sweethome3d.com/plugins.jsp".

Re: 3d View suddenly impossibly slow
Vij974, I’m happy you like this plugin but it doesn’t act on the 3D view, just on the rendering process. Could there have been an update in your system that speeds up Sweet Home 3D?

Re: 3d View suddenly impossibly slow
Emmanuel, I did not made any update on my computer. In fact the 2D object rendering and also the 3D rendering where very slow since a while. I discovered then the plugins so I wanted to test them (not to resolve the issue but just to test the plugin), so without any other change but after installing them the rendering gone well by miracle. I don't know what really happened but that's what I experienced and that's why I put this comment. I understand that there is maybe no link between the plugin and the 3D view but that what resolved the issue on my side. Good luck to everyone.
