Re: Poor performance on desktop application 3D View compared to HTML5 viewer.
OK, let's keep in mind that the program was running perfectly for months until, suddenly, it doesn't. That's not a graphic card problem but something in the interaction btw win10, java and sh3d has changed. Or course, this change may have caused sh3d to be 10 times more demanding on the graphics card, but that's sill a software problem.

Re: Poor performance on desktop application 3D View compared to HTML5 viewer.
Hi, same problem since few week. I reinstal old version of SH3D, no way. I think it appears with Java update. Waiting for solution. Thanks ! Win 10, 64 bits.

Re: Poor performance on desktop application 3D View compared to HTML5 viewer.
I tried again the installer version (coming with Java 8u51) and the Java Web Start version (with Java 8u131) in 32 and 64 bit under Windows 10 Creators Update on two different computers (an Asus T100 and another one running under Parallels Desktop), and didn't notice any slowdown in the 3D view. Let's wait for the the release of the first updates of the new Windows 10 version before concluding it's Java or Sweet Home 3D fault. By the way, I would be very astonished that the suggestion to install Java 3D 1.4 made by vinylspeed could make the program run better, because Sweet Home 3D always tries to use the Java 3D version provided with it. Running the program with Java 3D 1.4 can't be made without changing running options in an IDE, and it's not what he seems to have attempted (but still thanks for trying)!

Re: Poor performance on desktop application 3D View compared to HTML5 viewer.
Emmanuel, It feels like this is another poor graphics driver update bundled with windows 10. I wonder if you could ask everyone who's had this issue to try with webstart, as that uses a different exe from normal java http://www.sweethome3d.com/SweetHome3D.jnlp If that goes ok, then that tells us it's probably driver related.
The last major issue relating to drivers was the generic 1.2 driver which normally stopped everything from working, so I presume this is not that exact same issue.
Possibly checking the old d3d driver performance might help, but it's not easy, if someone with the issue could run this: open powershell on windows cd to a "Program Files (x86)" version of Java (which for me was) C:\Program Files (x86)\Java\jre1.8.0_131\bin> then run sweethome3d from there with the following command:
Notes: you have to use ./ or the normal java runs you have to use all the string quotes or powershell doesn't understand you have to use the -client version and all the other options mentioned or it will not load the java3d1.5.2 d3d drivers
If anyone with the issue could run that, and confirm the speed is ok, then it is almost certainly opengl drivers failing to load.
Also it might help if everyone who's had the issues reports what the graphics card in their machine is, by opening powershell:
wmic path win32_VideoController get name,driverversion

Re: Poor performance on desktop application 3D View compared to HTML5 viewer.
My problem concerns only the desktop version. Web version runs nicely. Another curiosity: I usually work in split secreen. There every manipulation of the 3D takes about 10sec. to be executed. So I move the courser "blindly" on a frozen 3D model and 10sec. later I get the rotation. However, I then switched to "show 3D in seperate window" and I could move and turn it perfectly, for about 30sec.. From then on (and even after restarting sh3d) it's also have the 10sec. stall. Btw. sh3d never crashes or slows down the pc or anything, it just takes 10sec to change the 3D and upon starting takes forever to "load" the bitmaps of furniture (all standard) in the 2D.

I tried with the DirectX version of the webstart and it runs considerably better.
