For reference: I work as an yacht designer and have over 20 years of experience with Rhino ie one get quite sensitive when something is out of order.
I currently run Rhino 6 and have recently bought a new laptop workstation (BOXX 17 SLM) with NVIDIA RTX A3000 card.
The Rhino files I work with are usually around 1 GB and I have not had any issues with Rhino 6 and the computer(s) I´ve had before this one. The new laptop is fast and fluent in shaded mode and runs generally nice …but when hiding/unhiding/show selected etc. objects in my scenes I now experiential quite an extreme lag, up to 1 min, and it´s intermittent so it works fine for some time and then it starts??.. reopening files helps sometimes …restarting the computer does help to an extent.
Hard to explain, feels like something spools up, can´t access memory or problem emptying cache (similar) wild guessing here. Thought it might have to do with heavy 3rd part models I use like imported STEP and IGES files of engines etc. this has all worked fine on ealier computers …and works fine on this new computer too …for a while??
tried to - Purge files
to Save as… unchecking - Save plugin data
wireframe or shaded makes no difference
NVIDIA driver updated to latest and all settings set to use full performance
Has anyone had a similar experiance or can shed some light here?
I wouldn’t want to ask this about a BOXX but is it overheating from too much power stuffed in a thin and light case and slowing down? You can tell from the “Resource Monitor”…which you get at from the “performance” page of the Task Manager…
Well I would hope it’s not on a BOXX, but… Are the laptop fans screaming like they’re trying to lift off when things get laggy? They probably should be…
Do you mean that I can monitor GPU temp in the taskmanager, this I see and I know there are specific software to monitor rpm, or is there something built in to Windows
I am under the impression that the RTX Ax000 series of cards is the successor to the Quadro series. I believe that as such they need the Quadro driver.
However, when I look on the Nvidia driver download page (Advanced Driver Search | NVIDIA) I see that there is no RTX A3000 listed under RTX/Quadro Product Type. Just A2000, A4000 and A6000. On the other hand under GeForce Product Type they show under Product Series RTX 30 Series the RTX 3060, 3070, 3080 and 3090. Under Product Series RTX 30 (Notebook) they show the same product numbers with “laptop” added to the name.
In either case the Dec 13, 2021 driver designation is 472.84. Rhino shows your computer with an Nvidia “A3000” Laptop with an older 471.41 driver in the Primary OpenGL section of SystemInfo.
It may be worthwhile to find out why the card is called an “A3000”, but I suspect it’s really an RTX 30x0 and needs the GeForce laptop driver. I noticed on the GeForce driver download page that there are two different incompatible types listed under Windows Driver Type with an explanatory note available by choosing the adjacent ?.
All this to suggest you update your Nvidia driver. Perhaps the Intel one as well. Even though you would think that what you already have should be OK for the Rhino V6 you are running.
Go to the Resource Monitor through the Task Manager, and monitor the CPU speeds. It should be over “100%” basically all the time unless it’s getting too hot.
Thank you for the info. I assumed the site I mentioned was pretty authoritative. I’m sorry I have nothing to add about your speed issue. I wish you success in curing it.
I doubt this is a display driver issue. For some types of geometry, the object properties panel can be slow. Try making the object properties panel hidden by choosing a different panel to show (try layers). Then select objects in your scene. Does this make a difference?
Hi, actually it is the CPU that is working harder when the above occurs and the fan is reving up but in a quite normal way. However the CPU only works at around 13% but this is normal I think with Rhino. What is it called single threading? Defientlely no my area of expertice …but I never see (ever, I think) Rhino using CPU to 100%.
I changed my computer recently so the project (Rhino) files I work on have been more or less the same before I changed laptop and after ie same files different computers = easy to compare. I just never experienced this behaviour on the Lenovo P51 I had before. The Lenovo being a little more sluggish in general feel but never this odd behaviour?
Files tend to build up in size over time adding more and more 3rd party models and other junk but I still did not have these issues before. If I break out (export) a smaller portion (dumping a lot of half obsolete info) it actually does work! But it is still annoying and should not be necessary, especially on a new and faster computer.
It might be something with how the new BOXX computer is set up …accessing RAM or similar??
…but I never see (ever, I think) Rhino using CPU to 100%.
