Re: Performance Issue on assemblies
Ryan Dark May 8, 2017 5:35 PM (in response to Sandro Pinho)Hi Sandro,
This forum has seen a lot of reports about slow performance with NVidia GeForce GTX cards. The consensus around here and across the user base is that upgrading to the very latest driver from www.geforce.com or rolling back to the previous driver is able to improve this. You will definitely want to try either or both of these (upgrading or rolling back the graphics driver) to see if it helps your situation too.
This solution article was released regarding this:

Sandro Pinho May 9, 2017 7:42 AM (in response to Ryan Dark)Thanks for your answer. Just to clarify.. I have my drivers up to date so I will try to install the earliest version and see if I have my probem fixed. Is that right? I should say that I have the files and solidworks installation on an SSD.

Tom Gagnon May 9, 2017 9:42 AM (in response to Sandro Pinho)As I understand it, or at least apply it on other cards, it is neither the earliest version nor latest version, but the certified version.
You can find the certified driver for your software at: Graphics Card Drivers | Hardware & System Requirements | SOLIDWORKS

Re: Performance Issue on assemblies
John Stoltzfus May 9, 2017 9:18 AM (in response to Sandro Pinho)Something I found out recently was the issue with sketches in an assembly file.. The sketches or sketch related items that are at the lower end of the feature tree controlling components within the feature tree are a huge reason for lagging models.
SW rebuilds starting from the first item in the feature tree and works down to the bottom, so if any part or assembly is dependent on any of the sketches that are after the last item or assembly, this can create a circular rebuild very quickly. The items can't be rebuilt cleanly, till the sketches are rebuilt, so you need to hit ctrl Q at least twice to make sure your items are updated..
Traffic light symbols in your feature tree proves that point and that is why I wanted to see the bottom end of the feature tree.. (Circled in blue.)
For a better explanation see the attached

Re: Performance Issue on assemblies
Sandro Pinho May 10, 2017 2:52 PM (in response to John Stoltzfus)What you are saying is that I should not use sketches to mate parts in place..
I can´t test right now what you said because it would be very time consuming to change all and I can´t right now..
But when I can I will give it a shot.
However I will pay attention to that detail next time.
Thanks

Re: Performance Issue on assemblies
John Stoltzfus May 11, 2017 6:43 AM (in response to Sandro Pinho)I would use sketches etc with caution, "if" they are below the last part in the feature tree. I would suggest that you setup your assembly template with sketches already in place, prior to inserting any parts, that way they stay up top where they will rebuild before the rest of the assembly..
