Powerpoint runs slowly erratically in Zoom

[adavies]

I run a Mac (Big Sur 11.6) and give  Zoom talks using lots of photo images. Powerpoint runs ether slowly with lag between slide, or jumps slides. Is this a Zoom issue or Powerpoint?

Thanks!

Hi @adavies, I am sorry I missed this! Are you still having issues with the powerpoint presentations? If so, please let me know.

I know this is an old thread but I can say I'm still seeing this issue.  Here is how it plays out.
Some parameters:   Same screen split out into two projectors and one LCD.  Wireless keyboard.  Wireless Logitech presentation clicker (from now on clicker).

• We can run through a PowerPoint no problem when Zoom is not running.
• We can run through a PowerPoint with Zoom running but NOT presenting.
• When we go to Share my screen and share the entire desktop is where the problem begins.
• Zoom logged in.  Share > Full screen.  PowerPoint (Microsoft Office 2019).  Set PowerPoint to "full screen" presentation mode.
• After going full screen with Zoom sharing.  And then maximizing the PowerPoint the clicker does not respond for 15 to 30 seconds.   And at points during the presentation the clicker may freeze.

And some answers to anticipated questions.   Yes, the clicker batteries are fresh (and tested with a battery tester).   Without the Zoom presentation running you can click forward and back on the PowerPoint very fast.  This works fine in Google Meet with screen sharing.   This has been observed in Zoom at three or four presentation rooms in different buildings.  Windows 10 22H2.

Similar issues on my end. When running a powerpoint presentation on ZOOM, the performance of my surface pen is severely impared. The lag is so bad that I will write entire words without being able to see any pen strokes. The word will then suddenly appear after I stop writing. This makes adding contant or drawings during the presentation almost impossible.

I am facing the same issue. When I start sharing my screen it is almost impossible to draw on the slides during the presentation in PowerPoint.

I am running laters versions of zoom and office, MacOS 12.7.3

Hello there,

I'm sorry for the late response. 

You can check out this article for screen-sharing a PowerPoint presentation depending on the setup of your device.

To improve PowerPoint's performance in Zoom, try these steps:

1.Close Unnecessary Programs: Close other apps running in the background to free up system resources.

2. Optimize PowerPoint:
- Compress media files in your presentation (File > Info > Compress Media).
- Reduce the number of animations or transitions.

3.Share Screen Efficiently: Share only the PowerPoint window in Zoom instead of the entire screen to reduce the load on your system.

4.Update Software: Ensure both Zoom and PowerPoint are updated to the latest versions for better compatibility and performance.

5.Check Internet Connection: A stable and fast internet connection can help improve the overall performance of Zoom and screen sharing.

i just bought a new laptop hp LAPTOP-F9QTASPS, with processor intel Ultra 7 155H 3.80 GHz, 32G RAM, window 11, microsoft new version 2 days ago.

When i used zoom with power point with only 1 slide  during my online class, why power point is so lag until the words written on power point couldnt come out after i wrote for almost 10seconds?

At first i thought it was my laptop problem as my previous laptop face the same problem, my previous laptop from 2020 may until jan 2025 had gone through the beginning version of zoom until latest version now. Last 3 yrs ago, i still can use power point with zoom very smooth, only this one and half year, its so lag. i thought the new laptop shouldnt have  such problems, but in fact, my new laptop face more severe lagging than my whats in my previous laptop during end of its life span! 

How can i teach students with this so lagging power point with zoom?
