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'

 Any suggestions? 

I wanted a budget webcam for my desktop Windows PC to use with Zoom and after reading some reviews purchased a Razer Kiyo X  Full HD Streaming Webcam. The image was crisp on the Zoom preview window but was extremely broken up with horizontal grey bars that jumped around. I tried changing the video settings including the advanced settings but wasn't able to resolve the issue. I obtained a basic Logitech C270 HD Webcam which works fine but leaves me with the question of whether the Razer was simply faulty or whether this is a known issue with Razer and Zoom and if there's a way around it. Thanks!

Hi, I'm having an issue and I hope someone can help.

I recently recorded a meeting. The Zoom Recording File shows up on my local folder, however it doesn't convert when I double click on it.

I'm unable to find the recording on the Zoom App.

I also can't find ztscoder.exe 

Any ideas?
