Is it Rhino 6 is more slow than rhino 5

Hi every one

on my computer, my rhino 6 is more slow than rhino 5.

please test this file

my computer config is
intel celeron E5 1620 3.5GHz
Quadro K2200 @ 4Go
driver date 10/30/2017.


rhino 6

rhino 5


Here is my computer test. Mine is faster in V6, have you verified your video driver is the most up to date? You should post your system info from the Rhino 6 help menu. It’ll help the Mcneel guys out.

Hi, Thanks for watching my post but, on your file, you have forgotent the text dot.

I have the impression than the display textDots is mor faster in rhino 5 than rhino6


i actualité dowload a new version of my Nvidia Driver. and I test again…


I just made up a file to do the test. Didn’t notice your text dots. How many do you have in there? I can replicate it closer if it will help. I added 50 text dots to the file and retested. Here are my results.


Looks like Rhino 6 was still in the lead for me. Hope your updated drivers help you out. I’m going to test this out again when I get home since I have a K2000 card there. I’ve got an AMD card here at work.

I have download the newest driver and test again.

the result is lightly positive for rhino 5 and 6

my file test contains 1600 block which contains 1600 dot.

Large amounts of text objects is also slow…

Hello - testMaxSpeed is about three times faster here in V6 than in V5. Try setting up V5 and V6 with the same sized viewport and no floating toolbars etc and see what testMaxSpeed tells you - then at least you can compare more directly.


I this mornig my rhino 6 is mor faster than rhino 5 :heart_eyes: but this afternone my rhino 6 is mor slow than rhino 5!!! :cry:

i try to find this problème

I think have find the response at the probleme. the cause is may be rhino5

1 I start my computer
2 i run rhino 6
3 I test the file with rhino 6 and i see than rhino 6 is mor faster than rhino 5.
4 i run rhino 5 and i test the file and i see the rhino 5 is slower than rhino 6.
But if i close rhino 6 and I run a new rhino 6 instance and i run the file test in rhino 6, i See the rhino 6 is more slow than rhino5 !!!

can you test this procedure for see if its the same in on your side

best regards

Hi @SMC2,

I just tried following your steps, but I can’t reproduce the problem. Rhino 6 ran at the same speed both times. You might have to give more detailed instructions, or maybe this happens because of your specific hardware configuration.

Please paste the information from Rhino 6 found in Help -> System Information...

Can you please try load-protecting this plug-in, restart Rhino and verify it is not loaded. Then do your speed tests again? Is Rhino 6 still slower?

Hi, I have unload lynx plug-in and i Hace test the file but
rhino 6 is not mor faster

Rhino isn’t really optimized for this case (a bunch of dots in blocks). I typically only optimize on models that users submit as being slow.

Yes but on my computer, this problem of slower display apears whit all model in rhino 6 :S
