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.

Re: 3d View suddenly impossibly slow
Hi there! I have a some trubles with sweethome3d. if sweethome3d.sh is looked like this? I have a super slow 2d screen. All menus is working perfectI cat to see all itema and command.
cd $BASEPATH run_java com.eteks.sweethome3d.SweetHome3D -open "$@"
If I have used this version sweethome3d.sh I have not to see menu items, clear screen. #!/bin/sh # # BASEPATH=/usr/share/sweethome3d JAVA_ARGS="-Djava.library.path=/usr/lib/jni \ -Dcom.eteks.sweethome3d.applicationFolders=$HOME/.eteks/sweethome3d:/usr/share/sweethome3d \ -Dcom.eteks.sweethome3d.j3d.checkOffScreenSupport=false \ -Dsun.java2d.opengl=true"

Re: 3d View suddenly impossibly slow
This is now happening to me. I've been away from the program for a while, so I updated when prompted. Now it's so very slow. Same laptop, same specs as before. Use the Java Web Start fixes it, but then I can't use the 'copy as new furniture' plug-in.
Was it ever figured out how to fix this without the Java? I tried the cmd line mentioned and it didn't change anything.

Re: 3d View suddenly impossibly slow
I'm running into this slowness, and none of the posted suggestions have fixed it for me. 2 other computers (Windows 10 and Mac) in my house can run this program wonderfully, but on my Windows 10 desktop PC, the 3D views are awful. The "awfulness" seems proportional to the number of 3D objects being shown.
"awful" = There is a delay between panning camera w/ mouse and the 3d view showing it. Also extremely low FPS (about 5 FPS I'd guess).
My system specs: Windows 10, AMD 1100T processor (pretty fast back in 2011), AMD Radeon R9 200 GPU, 16 GB of ram
My initial installation: Running version 6.2 Java version 1.8.0_202 - 64 bit (bundled JRE it looks like) Java 3d version 1.6.1 3d view (virtual visit) is "awful".
I reinstalled with command line options for java 3d 1.5.2 and 32 bit. 3d view (virtual visit) is "awful". To experiment around a bit more with my cabin model (which displays fine on another Windows 10 system): Panning the aerial 3D view is "awful". Panning the aerial 3D view, but only displaying 1 floor of my cabin (mostly just walls, windows, stairs), is about 30 FPS. Panning the aerial 3D view, display all floors+furniture of my cabin is about 2 FPS. Deleting everything in my model and drawing a bare room with 4 walls, panning the aerial 3d view is 60 FPS smooth, no lag (hence my "proportional" comment at the top).
Update system java to java version "1.8.0_231". Run app via jar (java -jar SweetHome3D-6.2.jar)
Running via jar, hiding the 2D view speeds up the 3d view. Same behavior as "experiment around a bit more with my cabin model" above.
Does anyone have any other things I can try? My system can run 3D games just fine. The other Windows 10 system in my house is using the same versions as my "initial installation" above. Thanks!
