Rhino 8 Slow Startup

[EricM (Eric Paul Marvets)]

Opening Rhino seems to be getting slower and slower. On a fairly beefy machine, it takes about 10 seconds to open a new instance. Using /stopwatch does not capture whatever the issue is.

The best way I can demonstrate the issue is to start clicking the _SetView icon once /stopwatch finishes. It takes another 6 seconds before Rhino becomes responsive.

Rhino is immediately usable when started in safe mode. The time /stopwatch reports is half a second less than normal, although I get a weird popup message:

Rhino 8 is extremely slow to open files

Tested workflow in the following order: I made certain all instances of R8 were closed. I opened a new instance of r8 I opened an existing Rhino 8 file, it also has the 10sec+ lag event. I only counted the lag event duration for #3 (the existing file).

byRhinoGadget
I also use this plugin. I saw that it was one of the obstacles to fast opening.

[wm_c]

What is RhinoGadget? (Its not a plugin I use or have loaded).

[EricM (Eric Paul Marvets)]

I tried, but that didn’t fix the problem. It shaves off maybe a second, but the long delay after /stopwatch is still an issue.

@wm_c

What is RhinoGadget? (Its not a plugin I use or have loaded).

It’s a big collection of a lot of random utilities.

byRhinoGadget

[EricM (Eric Paul Marvets)]

@stevebaer Any ideas I could try?

[stevebaer]

SystemInfo only lists plug-ins that have actively been loaded into Rhino when the command is run.

If you disable all of these 3rd party plug-ins, do you get different timing results?

[EricM (Eric Paul Marvets)]

With no plugins, the stopwatch is a second faster, but there is still the same 6 second lag after stopwatch finishes:

What else does safe mode do besides block plugins?

Blocking plug-in FSharpRhinoPlayground.

@EricM

What else does safe mode do besides block plugins?

Essentially turns off OpenGL GPU display.

[stevebaer]

I don’t have a decent answer for you at the moment. I’ll need to ponder a bit about how to figure out what is taking up the remaining time.

I have the same problem, but in a much bigger way.

I’m on Rhino 8, starting a new file takes about 80 seconds!

I’m using some plugins (also byRhinoGadget) and disabling them hasn’t changed anything.

I can’t understand where the problem is, whether Rhino or PC.

I attach some information hoping for help.
UPDATE: after trying to start Rhino in Safe Mode the startup time dropped to zero.

Since I just received the Space Mouse Enterprise I had a suspicion… I tried to disable the Space Mouse pugin and Rhino starts immediately.

Unfortunately for me the Space Mouse is indispensable.

Are there solutions?

See this thread, there is a new advanced setting that may help.

Rhino 8 is extremely slow to open files

Hi Dale, We are a large autocad shop with the exception of myself and roughly 6 or 7 other people (mostly industrial designers) in the US and Canada that have committed to using Rhino as our primary tool in place of autocad. The use of Rhino and Spacemouse had made the workflow exceptionally fast. Unless of course your Rhino with Spacemouse takes 10 seconds to open on every file. Our IT dept has no interest in helping with the issue as its considered a vendor problem (since spacemouse is not a…

Done. Solved!

Tomorrow I will start the construction of a commemorative statue in my city (in Italy) for this epochal event.

Thank you @Japhy @dale

Update: unfortunately the solution is neither definitive nor viable for me as the command icons (and strangely not all) are not loaded on the Space Mouse Enterprise display.
