Bug Report browser source not look like runing 60fps even obs and program is 60

[hodalaplus]

I found this problem because I develope a browser source page using html5 engine,
I set the browser source setting to 60 fps and the page also output on screen that it runing at 60 frame per second perfectly.(so the browser engine using by obs is efficient enought to handle this page.)

But the problem is it just look like only 15~20 fps in obs preview and twitch.

Setting the browser source to 5 will actual down the fps look in preview, but setting fps higher look like not affect, event the program is actual really running 60 frame in obs.

Is this a bug something block the setting number doesn't actual commit when setting fps higher than 30+, or is there a page that can verify my browser souce can run a animated page at 60 fps?

Here is an example page that showing it is running at 60 fps in obs browser source(by showing fps on page),
but actual look like 15~20 fps in obs preview.

(according to another thread, this demo must use --enable-gpu flag to start obs to get a right render of the page,
but this problem also appear in the html5 engine that dont need --enable-gpu flag in my case.)

.. is this feedback in wrong catagory? where should i post to get response?

So did you test with the --enable-gpu flag or not? The example page you linked runs pretty poorly for me in a regular browser as well, but I'm not sure if it's supposed to be a recording or a live demonstration of the code.

yes, I test the page with --enable-gpu flag, I give this page for example just because it have a live fps label, not because it is heavy computing, or any special case.

I have fonud another example for this situlation.(this page dont need enable gpu flag)

I suppose this is a simple and light computing case, and also it showed a fps label.
You can see a 60fps should look like in browser, then compare to it in browser source setting fps to 60fps.
At least on my computer, browser show smooth result, but browser source show laggy even it's a light computing page and
the setting and fps measure label in page both are 60 fps.

on my computer, the simple animation in browser source is laggy like run on 10~20fps, but the label in page show I give 58~60fps to browser source.

We can't do anything about performance, this is a CEF limitation.
