Question / Help Browser

[Banyarola]

I'm a little confused over the following:

I use a Browser Source to add my weather station from Weather Underground that I stream with my webcam.
It's a relatively still image that updates my local conditions every 10 to 20 seconds.

The default frame rate is 30 on the browser source.
I find lately it has been using a lot of CPU but if I change the frame rate to 1 it seems to minimize the impact on my CPU without compromising the quality of the image I am streaming.

My question is, under what circumstances does a higher or lower frame rate impact what you are streaming in the browser source??
I'm attaching a screen shot to help explain it more clearly.
Thanks..

Browser source is a rendering engine to make image from the html page (or so). More frames - more cpu power required to render all the frames in time. OBS Studio uses this images (from the browser source) to compose the final output (and then encode it).

Thanks, I suspected it may work that way.
I just don't understand why it uses so much CPU at times and so much less at other times. It's the same web page I am using. I also use stream two other wildlife live cams with the browser source and they are not as cpu intensive and they are live action bird cams.

Oh well, thanks for your help.. It cleared a few things up for me.

You may try to test default page for the Browser source (obsproject.com, there is moving picture, so fps setting easily noticeable at output). And who knows what CPU is doing right now...

Yes, I'll try that..
I'll let you know..

It's about the same..
Well, my system is kinda old so I guess when I build another one it will be better. I plan on doing that soon.

Thanks for all your help..It helped a lot..
