Been having this problem for two months with no resolution.
Computer is hooked up to Dual Monitors and works fine for the day until I join a Zoom Meeting at which point ALL of the computers apps, moving my mouse around the screen, etc. all lags.
AGAIN, computer only lags once I join the Zoom Meeting, even if my mic and camera are off and I'm not screensharing. All apps lag. Mouse movement lags bad which has nothing to do with internet.
About half of the time, I can unplug from the dual monitors and it'll speed up. Sometimes it requires restarting my computer for the computer to stop lagging even after the call.
Hardware & Software:
- Dell Latitude 7430 (new in March 2023) / 12th Gen Intel Core i7-1265U 1.80GHz / 32GB Ram / 64-bit, x64-based processor /Windows 11 Enterprise version 22H2
- TWO Dell 2422HE monitors with built-in docking station, daisy-chained and plugged into laptop via USB-C.
Modem hardwired to Monitors.
- Zoom v 5.16.1 (22523)....the most up-to-date available for my company as of 9/26/2023.
- Internet Speed Off of VPN: Download 295 MBPS (13 latency), Upload 294mbps (10 latency)
- Internet Speed On VPN: Download 20mbps (112 latency), Upload 54mbps (118 latency)
Solutions Tried: (restarted after all of them)
- Deleting Zoom, Reinstalling.
- Checking for BIOS updates daily.
- Checking for Zoom updates daily.
- Manually checked Graphics Driver Updates
- Manually checked monitor updates.
- I have tried all of these Zoom Settings - checked and unchecked all of these. restarted after unchecking/checking each. 'Use dual monitors' in General, Otimpize quality of the video I send with de-noise, optimize quality of the video I receive with super resolution, ALL of the hardware acceleration options, Video Rendering Method -> Direct3D9. 'Use TCP connection for screensharing' Use hardware acceleration for screensharing and to optimize video sharing.
- I had another set of dual monitors (Spectre brand, lower resolution) and connected to those with an external docking station. Same issue exists.
- Zoom on Cisco VPN and off of VPN.
- My previous company laptop ran on Zoom Meetings fine with these monitor set ups.
- I've tried this hardwired to monitor, and not hardwired.
- I'll close all apps but Google Chrome and/or Excel during the Zoom Meeting and it doesn't help.
- CPU and Memory rarely get above 60% and I have never seen them get above 70% even when computer is lagging like crazy.
- Processes that seem to correlate with when I join a Zoom Meeting and the computer starting to run slow: 'Windows Audio Device Graph Isolation' and sometimes 'System interrupt'
Experiencing computer lag after joining Zoom meetings can be frustrating, but there are several solutions you can try to resolve the issue:
Check Internet Connection:
Close Unnecessary Applications:
Adjust Zoom Settings:
Use Hardware Acceleration:
Update Graphics Drivers:
Check for Background Processes:
Restart Your Computer:
Close Other Devices:
Use a Wired Connection:
Contact Zoom Support:
Remember that the specific solution may vary depending on your computer's hardware, operating system, and network conditions. It's a good practice to try multiple solutions and see which one works best for your situation.
I have the same problem with a similar symptom. My internet speed is throttled WHENEVER I start the Zoom Client. I go from 900+MBPS Down and 40Up to 8 Down and 4 Up. However Physical and Wired Connections stay the same speeds. Whenever I QUIT the Zoom APP/Program on Windows 11 PRo, the speed of my PC Reverts back to higher speeds. at the reduced internet speed, my zoom meetings all lag now and affect all apps on this PC. After 5 months.... its the Zoom App/Program and Windows 11~! I can use Chrome Web Browser and take the Zoom meeting, and everything is fine. Speed stays throttled down whenever the client/app runs even if not in a meeting or phone call.
I too, am on Windows 11 Pro (corporate).
We deleted and reinstalled 20+ different drivers across laptop specific, ethernet, wifi, graphics, and zoom and none worked, so I ordered a new laptop.
I finally found one-person online that said the CPU and/or GPU will overheat even if it doesn't show that they're maxing out. He told me to frequently check the bottom of the laptop's temperature and see if computer lag correlates with A) Joining a Zoom Meeting and B) Computer lag starting, and sure enough that seemed to be the case.
I only had three days of testing before my new laptop showed up, but once I positioned my laptop fan/heat vents from lying flat on a surface to open air, the lag seemed to be completely gone. The computer stayed cooler too. I'm 90% certain now that it was an over-heating issue. I had the Dell Latitude which after googling is notorious for over-heating when running multiple monitors or other strenuous apps like Zoom.
If you are unable to immediately get a higher-performing laptop, I'd get a stand that doesn't cover your vents AND touches as little of your laptop as possible so heat dissipates. If you can expense or don't care to spend, I might would even get one of the cooling stands. Otherwise, you could makeshift like I have so far with a book that is holding my laptop off my desk, but allowing ~1 inch of breathing room.
Sounds like we had the exact same issue, so hope this works for you. I was miserable for 2 months, getting kicked out of client calls while presenting. One week in now without that stress and it's amazing.
I just ordered this $10 stand from amazon just to be cautious with my new laptop overheating. (Omoton laptop stand for desk ergonomic...)
Let me know if this works so i can troll my company's tech team for never considering over-heating and me figuring it out on my own.
I’m having the same issue. Tried every listed solution, got my cpu looked at for any malware and I even upgraded my hard drive to a 1TB SSD card and nothing works. This all happened suddenly in the middle of a meeting a month ago and it’s still unresolved.
