Problem: roop is not using my GPU

[Ulrichwolf]

Hello, When I run any activities with roop, Roop seems to not detect my GPU and only use my CPU. Do you have anny idea on how to change that?

[Ulrichwolf]

Now I'm able to make the GPU work a bit, but it still use the CPU a lot in comparaison to the GPU, is that normal?

There's no way to answer your question with the lack of information you're giving. Might as well guess the weather from a dark and soundproof room.

What are your system specs? (espescially graphics card)
What does "work a bit" mean? How much of the GPU is it using (in %)? How much VRAM, of how much available is it using (in GB)?
Did you install everything according to the wiki? Did you have any errors installing any of the needed components?
Did the roop-unleashed installer throw any errors?
How many threads are your running?
Are you using an enhancer? Which one?
What provider is selected in the settings?
What does the cmd output say, which execution provider is it using?

I wrote an extended piece in the FAQ regarding GPU utilization a while ago. Can't say if any of it will make a difference with live cam though, since I've never used it. But there are other discussions and issues regarding low fps with live cam. Just make sure you search for closed and answered ones, too.

Thank you for replying me, I have read all the issues and discussions but not found how to fix it. I tried up to 20+ thread, but nothing happen. I think there is something with the default fps of output live cam. Because even when I have not upload image to do faceswap, the output live cam fps is just 1-2.

Hi - since you are using CUDA - I'm assuming you have a NVIDIA graphics card. If so, I was experiencing a similar issue with my RTX 4070 TI and it was due to default NVIDIA settings for memory utilization.

Take a look at this article from NVIDIA, you need to establish settings that prevent the system memory from being used as a fall back -- -- https://nvidia.custhelp.com/app/answers/detail/a_id/5490. My GPU usage now is around 85-90%, previously was around 10-20%

//edit - lysxelapsed - if this ends up being a fix for this individual, I wonder if you would be able to update the FAQ to provide this information to NVIDIA users? I am not sure how to do that as I haven't really used github before and don't want to clutter your work. I just made this account to reply to this thread.

Thanks, I added it to the FAQ. For some users who get close to their VRAM max, this might indeed be the solution 👍

Thanks to you all for your support. The low fps and gpu usage in the (browser) live cam however is happening because there is no gradio streaming control and the image control I'm abusing for display isn't rendering fast enough. There is an issue about this here
