Engine COMPs on build 2025.31550 seem to get stuck at the “engine_launching” state when initializing. I’ve tried loading several different kinds of tox files (files made with builds 2025.31550 and 2023.12230), but none seem to start up successfully. For testing, I loaded the same project file (created with build 2025.31550) with builds 2025.31550 and 2023.12230, and can only get the engine COMPs to load successfully within build 2023.12230.
I’ve included a zip file containing the .toe and .tox files I used for testing.
Thanks, and let me know if you need any further info!
Another interesting thing I noticed (though I’m not sure how related it is) is that the TouchEngine processes are also not killed successfully when exiting the program.
It would be helpful if you could generate a dump file from one of the hung TouchEngine instances - could you open Task Manager, select TouchEngine (after an Engine COMP has been stuck for a while, or after quitting TouchDesigner), right-click and select Create memory dump file. The resulting file will be large but should compress well. Please either post a link here or send it to support@derivative.ca linking this forum thread.
It’s possible the integrated GPU is being used, so you should update your Intel graphics drivers as older Intel drivers are a known problem for TouchEngine: Download Intel Drivers and Software.
Then make sure TouchDesigner is running on the correct GPU - you can use a Monitor DAT in TouchDesigner or the Details section of Task Manager. If your laptop has its own power management software, make sure TouchDesigner is allowed to run on the Nvidia GPU.
As it’s running in 2023 builds, this may not be the issue, but worth eliminating as a possibility.
I’ve gone ahead and updated all Intel related drivers on my system, and have not seen a change in behavior. I can also confirm that monitor DATs show that TouchDesigner is using my system’s A2000 GPU.
I’ve zipped together a few memory dump files, with 3 files being dumped before closing TouchDesigner, and 3 files after closing TouchDesigner. I’ll go ahead and send them in an email to the support address you mentioned!
Could you let us know the model of GPU and the driver version? Update the driver if it isn’t current.
It’d help if you’re able to share the .tox (and any related assets). Either post them here or send them to support@derivative.ca with a reference to this forum thread.
@ab_out - it’d be helpful if you could follow the steps in my post above re drivers for any integrated Intel GPU, obtaining a .dmp file and checking the correct GPU is being used
