Marcus Bertilsson Posted August 18, 2006 Share Posted August 18, 2006 I'm feeling that V9 is slower handling big assemblies then V8. It is harder and takes longer time to get smartsnap points for example and also to get visual feedback for selection of part/assemblies in scene browser. Is there anybody feeling the same? / Marcus Quote Link to comment Share on other sites More sharing options...
Cary OConnor Posted August 18, 2006 Share Posted August 18, 2006 Make sure you set the rendering back to OpenGL. It gets reset to Automatic on uninstall/reinstall. Cary Quote Link to comment Share on other sites More sharing options...
Guest jkim522093 Posted August 21, 2006 Share Posted August 21, 2006 Some designers here also feel that V9 is slower than V8, and they say it is a little "sticky" when manipulate the large assembly scene. Of course, they returned to OpenGL in rendering option. JH Quote Link to comment Share on other sites More sharing options...

Guest IronKevin Posted August 26, 2006 Share Posted August 26, 2006 Are any of you using 3D Sections in your assemblies? IK Quote Link to comment Share on other sites More sharing options...

Guest IronKevin Posted August 30, 2006 Share Posted August 30, 2006 After exhaustive comparisons between v8 and v9 using the same files and computer, I'm failing to see a performance difference. Please send me the details of your findings and any files you used to compare v8 versus v9. I would like to be able to accurately quantify any performance differences. Thank you for your assistance, IK Quote Link to comment Share on other sites More sharing options...
Guest jkim522093 Posted August 31, 2006 Share Posted August 31, 2006 With the attached simple file, created in version 8.0(might be earlier), when we rotate it in V9.0, then we feel it is a little sticky. (I'm not so sure if the word "sticky" is good to explain what we feel, but when we click the mouse to rotate the scene, then the responses are slower than V8.0, and we feel heavier in V9.0.) And if we make three or four copies in the scene, then we feel much slower responses in V9 when rotate/pan/zoom the scene.

Mike Twining Posted August 31, 2006 Share Posted August 31, 2006 I've been following this thread for a while, and I can't help but get the feeling that is has something to do with the new(er) edge delay settings. Those of you who feel there is a reduction in speed in v9, have you tried reducing the edge delay time? Quote Link to comment Share on other sites More sharing options...
Cary OConnor Posted August 31, 2006 Share Posted August 31, 2006 Here is that model rotated on my machine in version 9. Are you seeing something different? Cary Rendering.zip Quote Link to comment Share on other sites More sharing options...
Guest IronKevin Posted August 31, 2006 Share Posted August 31, 2006 Mike, how does the IC_V6_Demo_306.ics file perform on your machine? And if you wouldn't mind letting us know your graphics card spec. thanks, Kevin Quote Link to comment Share on other sites More sharing options...
Mike Twining Posted August 31, 2006 Share Posted August 31, 2006 That model screams on my machine, but most models do. I've got myself: 2x Dual Core 3 Ghz Xeon Processors (64 bit) 32 Bit Windows XP 2Gb Ram (with the /3GB swithch) Nvidia Quadro FX 550 Video Card (running 2 displays) You gotta have quite a few more parts before this machine starts to choke on anything...

Guest Urban Olars Posted September 1, 2006 Share Posted September 1, 2006 I enabled the nView Desktop Manager today and noticed some strange effects after that. As soon as the mouse cursor was over an IronCAD 3D scene window, it felt like dragging the cursor around in syrup or something. Very slow. Rather difficult to select shapes too. Outside of these windows, the cursor was like normal again. After disabling the nView Desktop manager the behavior went back to normal again.

Mike Allen Posted September 1, 2006 Share Posted September 1, 2006 I found that same problem back with IC6 or 7 (whenever we first got the nVidia cards on our systems.) Have not used the nView Desktop Manager since. I haven't noticed any speed-related issues with IronCAD 9. As far as I can tell, it performs all operations at the same speed as in IronCAD 8. I normally work on extremely large models (on a scale of about 900 square feet or bigger), with a moderate level of detail (we don't show fasteners, or any internal detail for most parts - but we have a lot of curved surfaces, so there are lots of facets.)

Guest IronKevin Posted September 1, 2006 Share Posted September 1, 2006 One other note regarding the Scene Browser, just like using Windows Explorer in a folder containing hundreds of files you are going to see a drop in performance the more parts and assemblies that are expanded. So, it is a good practice to collapse items you are currently working with to keep the displayed list under 200 or so. IK Here is the structure list of a large assembly that contains 3184 parts and performs well in IC9 (without nView ). But with all parts expanded in the Scene Browser the selection in the Scene Browser slowed. I can't upload this customer file but it's a 50mb single Scene file.
