Rhino 8 is extremely slow to open files

[wm_c]

We generally open and create DWG files created in Rhino.

The latest version of r8 is very slow to open. As we are expected to open, close and create a large number of files in any given day, this is causing a lot of frustration.

Any idea what’s going wrong?

SystemInfo looks fine. This is experienced on multiple machines?

@wm_c

We generally open and create DWG files created in Rhino.

Can you provide more details on the process and a file that is exhibiting the behavior? Thanks

[Japhy]

These are local files or hosted somewhere else?

If you open Rhino in safe mode (via Windows Start) does it open quickly?

The systemInfo looks ok for graphics config but that can be deceiving sometimes.

Soooo, you bought a laptop with hybrid graphics and rhino doesn't run right. READ THIS

Hybrid graphics laptops are more and more common if you buy a consumer grade machine. (I recommend buying a mobile workstation for professional modeling but these hybrid machines are quite prevalent in the consumer market, especially for students.) They tend to generate a TON of tech support here because of the way they are set up from the factory. Hybrid systems are built with 2 graphics processors. A low power graphics chip (typically Intel HD or UHD) and a high power graphics card. However…

[wm_c]

The files are all local (I turn OneDrive sync off during the work day)…even checked to make sure it is actually off…it is.

Rhino opens quickly in safemode (with a plugin warning)

Rhino is set for high performance (IT knew to do that before we received our laptops).

Rhino has been running great until the latest rhino software update.

[Japhy]

The safe mode helps narrow it down by unloading all plugins and not using the video drivers.

We can try disabling import_ACAD.rhp via pluginmanager in safe mode and then reopening Rhino normally

[wm_c]

Sorry, was interrupted before I could make and test this change.

Ill try test disabling the ACAD plugin next.

[wm_c]

Same slow start without the acad import plugin loaded

[Japhy]

Leaning towards something about the video setup. Clean install of the Nvidia driver would be the next step.

[wm_c]

I always do a “clean install” of nvidia drivers (a hold over from the days nvidia always had install issues).

I reinstalled the current driver just in case it somehow has become corrupted.

Still the same slow startup issue.

[Japhy]

Lets create a stopwatch flag.

Copy the Rhino 8 shortcut and edit the properties and add the flag /stopwatch

drag and drop a dwg to the icon to start Rhino.

Grab the report data generated in the command line.

Thanks

Is the test to start a new instance of Rhino and open a dwg file or are you seeing things being slow with an already open copy of Rhino that you are constantly opening different dwg files from?

[wm_c]

When I open any file it takes approx 10+ seconds before I can access the open file with any commands.

If I try to do anything the screen locks (greyed out) with the warning to force close or wait for the file to proceed.

[wm_c]

Is Rhino stopping to run a license check, causing the startup lag?

[stevebaer]

I’m still unsure if you are including the start up time for Rhino in the description of your problem. If you start Rhino and open a file, then open another file without restarting Rhino. Is there a long delay?

[wm_c]

Tested workflow in the following order:

1. I made certain all instances of R8 were closed.
2. I opened a new instance of r8
3. 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).

[wm_c]

Thank you, appreciate the suggestion but no luck. The lag atill exists.

[wm_c]

Thank you,

My only option is to turn OneDrive OFF.

Did this and it had no effect on the file lag.

[wm_c]

Just tried an uninstall/reinstall, as a last ditch effort. No love.

[stevebaer]

Hi Walt,
I’m not sure if this will give us any more insights, but it is worth a try.

• Start Rhino and run TestTrace; on the command line set Enabled to Yes
• Open your dwg file
• After the file is done opening, run TestTrace again and click the save option to save a json file on your computer.
• Please send me the json file and I’ll see if there is any information in there that can help us better understand what is taking time
• When you restart Rhino, tracing will be turned off again.

Thanks,
-Steve
