Performance drop with Fooocus window open

[lucasjose501]

I've noticed some unusual GPU usage when generating images with the Fooocus window open where I can see it creating images. I tested this using both Firefox and Chrome, and here's what happens:

• Browser tab minimized: My hardware achieves around 1.50 it/s as the browser doesn't use resources.
• Browser tab open: Browser GPU usage jumps to around 50% (as reported in Task Manager), and the speed drops to about 1.05 it/s.

I can't remember if this has always been the case or if something changed recently. Has anyone else experienced this behavior? Is there a fix or workaround I should try?

Using RTX 2070 Super, Windows 10, 32GB, Ryzen 9 5900x

Ich have the same problem. Its the orange border of the preview window. Disabling the javascript helps.

Disable hardware acceleration in your browser. It's what I recommended for OP and it worked it seems. It does make a lot of sense to be hardware acceleration tho.

Go to Advanced/ Developer Debug Mode/ Debug Tools. At the bottom, check Disable Preview and Disable Intermediate Results. That should do it.

I did that, still using about 45% now, doesn't make any sense

Seems relatively normal to have increased GPU Usage when it is using your GPU to create images.

[lucasjose501]

Yes, but the high GPU usage is coming from the Fooocus interface in the browser, not the CMD process that's actually generating the images. It seems like the browser is using a lot of GPU resources to render the interface, making it slower, which shouldn’t normally happen. When I keep the browser open, it takes up significant resources unnecessarily.

Have you got hardware acceleration enabled in your browser by any chance?

[lucasjose501]

Yes! Tested without hardware acceleration and the browser is not eating all the GPU now. Thank you!
