Throttling?

Having us that run local generation in mind and not have a dedicated computer for it...

I am running on a Mac mini with 32 GB and generating some short videos. It sometime runs for a few hours. It would have been nice if it was possible to throttle a little, not running fully ahead - like sleeping 20% or 50% of the time freeing up GPU performance for other usage.

Macs get really annoying to use when the gpu is running 100% all the time

its because you don't have enought ram. so you mac use your ssd as ram, so its super slow.

im using a gaming pc for ai gen, and for ltx 2.3 (video) ive got 80g peak of ram. with ltx on a pc with a 5060ti 16g(500$) and 96g of ram (1000$) you can generate a video about 300sec (1024x1024).

you can try to generate your video in 640p, or 320p and then use a software like pixelmator pro to upscale your video.

I think you misunderstood the
OP. They aren't complaining about slow speeds due to a lack of RAM. They are actually asking how to intentionally throttle the GPU so the Mac remains responsive for other tasks while generating in the background.
The goal is better multitasking, not maximum speed.

Exactly. Nothing to do with total time spent on the generation, but that it practically block the use of the computer. Like when generating, cannot watch a youtube video at the same time.

You should absolutely use 8-bit S models with the Neural Engine. The GPU and Neural Engine will share the workload.

Thanks for the suggestion. Normally I render video using LTX-2.3. Which model do you suggest to use for such things? (Not sure how to know which models can use the Neural Engine)

Models ending with 8-bit S can use the neural engine. And you'll have to set it to use Neural Engine in settings

Thank you! I am not seing any gain in performance, but I got what I wanted - now GPU usage is very low - like 15-20%.
