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!

Re: 3d View suddenly impossibly slow
I'm a new user and have designed a multi-level home on the desktop version of Sweet Home 3D, all the while with a huge delay whenever I used the 3D Aerial View or Virtual Visitor, so much so that I rarely used the 3D features. I am running Windows 10 on a Dell Inspiron 7000 Laptop running an Intel Core i7 processor with 16GB RAM. To my knowledge, I don't have Java on this computer. Then one day, the 3D started running instantaneously! I would make a change in the plan and it would show up instantly on the 3D model. In aerial mode, I could change the view any way around with the mouse and the image changed instantly as I moved the mouse. It was a real pleasure using the program. Then I think I closed the program and the next time I started it up and reopened the same file, back to unworkable slow. I have no idea what happened or why the 3D vastly improved for a day! Would appreciate any tips. Thanks
I had similar issues on my Laptop with an on-board Intel HD graphics card as well as an on-board Nvidia GeForce. 3D view in SH3D was terribly slow, it took abot 20 secs to render a single image.
At the same time, I noticed in my NVIDIA monitor application that the graphics card was not used at all. So all 3D calculations had to be done by the not-so-fast Intel HD card!
I opened the NVIDIA system settings, there "3D settings" and there was an option "preferred grahics processor" which was set to "automatic. I changed this to "NVIDIA high performance graphics processor".
There was also an option "OpenGL rendereing processor" which was also set to "automatic". I also changed this to "GeForce".
After that, the 3D view in SH3D was lightning fast. I also noticed in the NVIDIA monitor application that there was now a java process using the graphics card.
This means that the "automatic" settings that were set before didn't automatically choose the fast GeForce but the slow Intel HD card to do the rendering!
So always make sure your graphics card is actually used for rendering the 3d view in SH3d and change your grapphics card settings accordingly!
Hi to all My laptop has 2 GPU: intel 4000 & Nvidia 960m So I set up to run sweethome3D with nvidia and 3d view works with this GPU (as I could see in task manager) While 3d section in split view in the main window all works smooth and fast. No glitches etc. But when I open 3d view in separate window (Ctrl+Alt+Y) then rotating, moving virtual visitor become slower with noticeable glitches sometimes. Look like separate window isn't optimized... Is there some truth in my hypothesis?
