Isadora 4 Severe Lagging
-
I'm running a laptop that should theoretically have no problems with my Isadora project - some basic video and image effects, keyboard watchers, layering and blending, nothing crazy. I'm on a Dell Precision 5690 with Windows 11, 64 GB RAM, 1 TB SSD, NVIDIA RTX 3500 Ada. I've manually adjusted 3D settings in the NVIDIA Control Panel such that Isadora always uses the NVIDIA graphics card and not the integrated Intel graphics card. Yet, when I try to run the file, my computer continually lags and sputters, and the load spikes to the 180-200% range.
This is my university laptop, so at first I figured it was an issue with the security permissions. However, after running several tests with our IT department with and without the security and granting Isadora all permissions, the problem persists. IT even tried it with another university laptop with lower specs, and that laptop had no issues running the file, so we think that rules out the security. I also tried the file on my personal laptop at home which has slightly lower specs, and again no issues at all.
Has anyone run into a similar problem? A laptop that should theoretically have no trouble running Isadora struggling? What can I do to fix this?
Thank you!

I wonder if it's possible to disable the Intel GPU in the BIOS? I know that Dell have made that increasingly difficult to do...
https://www.dell.com/community...
In that thread's a suggestion to actually disable the Intel GPU in Windows device manager.
Do the other university laptop, and your personal laptop, have multiple GPUs as well? -
It's possible you are running video through the Intel GPU, by using certain plugs.
On many laptops some video ports connect direct to the Intel GPU while others may connect direct to the dedicated card. Unfortunately not all machines handle this as smoothly. Some introduce significant bottlenecks while others can use both rather quickly.
Try detaching any external displays, and see if that speeds things up. The Load should drop instantly if this was the issue.

@dusx Thank you so much for the help. Unfortunately no luck, I disconnected all external displays and it was still spiking up to 180% with a keyboard watcher connected to a colorizer.

I'm on basically the same machine as you and any time I've had a problem like this, it's been the video codec. Maybe try re-encoding the video with Shutter Encoder? Use the HAP codec - any of the wrappers will do. Note that this will make the video unplayable in windows media player, but VLC will work.
Cheers,

@mark_m Thanks so much for your help. I couldn't do that in BIOS, and though I found it in device manager, I need admin permissions to disable it. I can ask my IT department if they'd be willing to disable it tomorrow.
I'm not sure if the other university laptop has multiple GPUs, but my personal laptop at home does. I also have that one set to default to NVIDIA for Isadora, but I didn't disable the intel GPU on it.

@citizenjoe That is so strange! I wonder why that happens with some Dell models? Unfortunately I don't have permission to download programs without IT (they're very strict) so I can't re-encode it to HAP with Shutter Encoder (at least not right now) - could I try a different codec that I could export from AfterEffects, or do you have an alternative re-encoder I could try?

You may not be able to do this without IT, but you can install the HAP codec for Adobe Creative Suite and do it direct. For the sake of trying it, could you convert the media files on a different computer?
You can try H264 if you're not working interactively with the files. Look at tips 5, 6 and 7 here: Hot Tips to get the Best Performance from Isadora : TroikaTronix for further ideas.
Also here: Create Windows Native HAP avi Video Files : TroikaTronix
For the record, my machine works REALLY well with Isadora and I do have the A4000 GPU running independently of the integrated graphics!
Cheers,
Hugh
