Geekbench 6696 not enough for screensharing?

I can't seem to use Zoom nor OBX for screensharing. DO I really need a more powerful computer? Tuple runs fine but my clients don't all have Macs.
Is screensharing normally this demanding? I remember I could do it better than this 15 years ago with VNC....
Check your memory graph for how much 'Swap Used' you have and 'Memory Used' -> 'Compressed'. Pressure on these metrics has made macOS chug along for me.
The 13" retina MacBook Pro is a lovely form factor. I've had good use of a late-2013 2.4GHz Core i5 rMBP and an early-2015 i7 for a bunch of things including video-conferencing with Webex and Zoom. I've hosted presentations without problems, but memory somehow got in the way of smooth operations with Mojave and Catalina.

I use Zoom just fine on a 2012 RMBP. I don't even think the fan spins up very much.

I wonder if your OS is up to date enough...
I used screensharing in zoom on a 2015 MacBook Pro as recently as a month ago.

Best answer: Hi,
I have an Early 2015 13" Retina MacBook Pro. It has the 2.9 Core i5 and is usually pretty zippy.
When I am sharing out my screen and using my camera with Google Meet or Zoom, it does get quite laggy and the fans spin up a lot. If I turn off my camera video, and the other caller does as well, it calms down and is smooth.
When others share their screen to me, no problems.
My guess is the additional work of compressing and sending an entire screen of video, plus the camera video, is what does it. It more than doubles what the local computer has to do.
If seeing your face while you present is not critical, I would suggest turning your camera off when you present your screen, then back on when you are done.
Something something GPU very fast at decoding/streaming video but Zoom makes it pass through the CPU? Something something?

I would try temporarily changing the screen resolution to something lower. Here's the Apple support page with instructions for that. A scaled resolution of 1680 x 1050 might improve performance because it would give the system a lot less pixels to manipulate, and it shouldn't degrade image quality too much.
Seconding checking for OS updates, as there might be new graphics drivers that could help.
Also make sure you've quit any programs that aren't directly necessary for screen sharing.
And it might be useful to play with encoding/compression options in OBS.
