V6 much slower than V5

rob.hoekstra · July 2, 2018, 1:22pm

Dear Helpdesk

I used taking Rhino models with me on my laptop (Samsung New Series 9) to clients. Although not extremely fast, it worked quite well. Now with V6, the speed went down to a level it is not workable even not with only one view in wireframe mode . Pls advice what settings to select to get old speed back or advice otherwise
(Reason for upgrade was promise of increased speed.)

System:
Processor Intel i5-3317u
Installed RAM 8 GB
Video
Intel® HD graphics 4000
Render version 4.0
Video mem: 2GB

Hi Rob,

Can you run the command SystemInfo and paste the result here, it can give a first insight on the possible cause.

Furtermore it’s always wise to update GPU drivers.

Also it’s good to know what type of files and geometry you are working with. Can you drop a file here that you experience this slowdown with so we can test possible causes?

Hi Willem,

Dat kan alleen maar nederlands zijn.

Zoals verzocht, output hieronder.

Verder alles langzaam op deze laptop. Zelfs model met maar 1 lijn.

Hi Rob - see if getting the latest driver from Intel helps at all. I would say don’t rely on Windows giving the right info about driver availabilty - check yourself on the Intel website. That said, I don’t know how the 4000 is going to work with V56. V6 makes many more demands on the video card…

Something else to try is to disable the bullant plugin in Rhino’s plugin manager. Restart Rhino and see if that makes a difference. Bullant may (or may not) be slowing Rhino down. It’s just a good thing to test.

rob.hoekstra · July 2, 2018, 3:46pm

Bullant disabled and video drivers updated. No diff. :-/

After running SystemInfo I also noted:

‘Use accelerated hardware modes: On’

If I am correct, this had to be Off at V5. Should it be on at V6? If not, how to switch off?

It should be On in V6.
What is the date of your display adapter driver now?

rob.hoekstra · July 2, 2018, 4:07pm

Driver Date: 12-11-2017

John_Brock · July 2, 2018, 4:15pm

This might be newer:

rob.hoekstra · July 2, 2018, 4:48pm

Okay,

I downloaded and installed the driver from site indicated by you. Same site as I visited 1hr ago and downloaded same driver (again). Re-installed the driver, restarted the laptop and started Rhino again.

While the intel site indicates a more recent date, SystemInfo gives again Driver Date: 12-11-2017. Nothing seems to have changed. However,…

…and I do not understand. The laptop is up to speed again???

So problem not solved but gone any way which is okay for me as well.

IT moves in a mysterious way

tx for your effort and have a nice evening.

John_Brock · July 2, 2018, 5:01pm

Any thoughts here @stevebaer?

stevebaer · July 2, 2018, 5:02pm

I don’t quite understand. It sounds like the driver update took effect after a reboot and everything is working now.

John_Brock · July 2, 2018, 5:09pm

Maybe that’s it.
@rob.hoekstra: Did you reboot after the first driver update?

rob.hoekstra · July 2, 2018, 5:26pm

Yes rebooting all the time.

Kind regards, vriendelijke groet,

Rob Hoekstra

Gents,

Just to revert a bit more clear,

Just to be follow John’s advice, while knowing I know it should be useless as I had done it already, I went twice through the cycle.

download latest driver,
install driver
reboot and check Rhino speed.

Only after the second cycle it worked and Rhino was back up to speed.

Strange? Yes!

Problem solved? No

Problem disappeared? Yes

tx again for your help.
