OBS 28 too powerful for an i3 Intel Mac?

I got a question does OBS 27 work with an i3 and not OBS 28. If it's true that's OBS 27 works well but OBS 28 does not I was wondering if I could find a stable version and go back and retro load the old version. I can't figure out how to use GitHub correctly. But that seems like the only place to find version 27.

Also does version 27 have RGB additive blending which is what I need for red and cyan 3D streaming.

I noticed obs28 does it well because I desaturated the color capture and just captured monochrome and in a second step tinted that red and cyan.

If RGB additive blending is not available in 27 am I allowed to have two different versions version 28 for red and cyan broadcast and version 27 for full color 3D broadcasts.

I noticed the further you go on the more power you seem to use so hoping that cutting the color gave me enough power to run everything. And I'll use the less powerful obs27 for my traditional full color filming.

Is my assessment correct about that?

I noticed only recently my USB cameras have been cutting off in the middle of a broadcast and freezing. Maybe it has something to do with OBS 27 being less intensive than obs28.

As my setup uses NDI, I've not upgraded yet to v28. There are some new options and capabilities, and a new user interface library in use (impacting plugins, etc). But I've not read of OBS Studio v28 base setup being that more resource demanding than v27

That said, real-time video encoding is VERY computationally demanding. And an i3 is a low-end CPU.

I recommend monitoring hardware resource (CPU, GPU, RAM, Disk I/O, etc) utilization to see if your system is being maxed out with your settings. And beware which options/filtering, plugins etc you run as some can have a big impact. And you need to be considerate at the Operating System level of what is running in the background. So it depends on your expectations, as to whether OBS (any version) is too much for you i3 (of which there are many generations and different power levels, so saying an i3 really only tells me low-end x86-based CPU, not the newer Apple-native M1/M2 silicon. beyond that, huge performance differences exist within i3 models/generations). And then ther is how much RAM, and do you have a SSD or HDD.. these things make a difference.

If you saw a big difference in performance after upgrading to v28, I'd see what defaults changed, and then what did you add? If you started using new features, those could easily have a CPU impact that is driving your system into overload. Which settings? no way for any of us to know with what you've posted. If you want someone to check your OBS settings, followed pin post in forum about posting OBS log. Note that recent OS changes (like if you upgraded to latest MacOS) may have had a big impact

Where is the best place to learn about the NDI fix? Here I imagine? I'm rolling along fine with 27.2.4 on a MacBookPro16,1 with my DSLR, but, I did like the new UI when I did have 28 installed for a moment.

These forums (Mac and Windows) have lots of discussions about NDI and what people are currently doing, and what works for some. But that is a thread hijack, so I'll leave it at that.
