Problem: Experiencing poor video quality in Microsoft Teams. Notification states “poor network quality.” Incoming video is laggy and choppy, while outgoing video and audio seem unaffected.

System Environment:

OS: Windows 11 (x64-based PC)

System Model: Z790 A PRO X WIFI7

Processor: Intel Core i7-14700K @ 3.4 GHz, 20 cores / 28 threads

RAM: 64 GB

GPU: NVIDIA RTX 4090

Network: Wired Cat8 cable (brand new), also tested Wi-Fi

Display: 4K monitor (resolution adjusted with no change)

Troubleshooting Performed:

Restarted modem and router

Cleared Teams cache

Switched between wired and Wi-Fi connections

Ran speed tests (600–700 Mbps consistently)

Adjusted display resolution

Verified no issues with other devices on the same network (including less capable machines)

Contacted ISP, who confirmed no issues after testing/pinging equipment

Notes:

  • The issue is isolated to Teams; all other applications and devices on the network perform normally.

Request: Assistance identifying the cause of poor incoming video performance in Teams despite high-performance hardware and stable network speeds.

Hi @Dustin Braley,

It's wonderful news that your issue has been resolved. I truly appreciate your effort in finding a resolution. I believe that many users may encounter similar issue, and your case could serve as a valuable reference for them.   

Therefore, I would make a brief summary of this post so that other forum members could easily find useful information here:  

Issue Description:

Incoming video in Microsoft Teams was consistently laggy and choppy, despite stable network speeds and high-performance hardware. Outgoing video and audio remained unaffected. Teams displayed a “poor network quality” notification during calls.

Assessment:

After extensive troubleshooting, including hardware checks, network resets, and cache clearing. The issue was traced to a third-party network optimization tool: Gigabyte cFosSpeed, installed via Gigabyte Control Center. This software was interfering with Teams' incoming video stream.

Resolution:

Uninstalling cFosSpeed immediately resolved the issue. Teams now performs normally with smooth incoming video.

More Information:

cFosSpeed is known to manipulate packet flow for latency optimization, which can conflict with real-time applications like Teams. If you're experiencing similar issues and have motherboard utilities installed, it's worth checking for and removing cFosSpeed or similar traffic-shaping tools.

As other users may search for similar issues in this forum, your post and solution will be a helpful reference. If you found this helpful, consider voting or marking it as a solution to make it easier for others to find.

    Hi @Dustin Braley,

    Good day! Thank you for reaching out to the Microsoft Q&A forum and sharing your detail.

    You're experiencing laggy and choppy incoming video in Microsoft Teams, despite having high-performance hardware and stable network speeds. Here're some suggestions you can try  to fixit:

    1. Use Call Health

    • While on a Teams call, click the More (...) in the meeting window
    • Select Settings > Call health to open a right-hand pane with live metrics on network, audio, and video performance.

    User's image

    • Check especially received packet loss, jitter, and received resolution/frame rate. They'll offer real insight into what's happening under the hood. Because even with fast speeds, packet loss or jitter on the receive side can degrade incoming video quality sharply - even when other apps seem fine.

     2. Look for Packet Loss, Jitter, or Throttled Receive Bandwidth

    The Call Health tool will show key network metrics:

    • Received packet loss should be < 2%
    • Received jitter ideally < 30 ms
    • Teams receive limit can clamp at around 1.5 Mbps. If your network has issues, Teams may deliberately cap receive bandwidth.

    If these aren’t within acceptable ranges, even intermittent network noise (NIC, router firmware, Windows QoS) could be throttling your video.

    3. Lower Display Resolution temporarily

    • Teams can struggle with 4K monitors, especially when docked.
    • Try switching to 1920x1080 during meetings to reduce rendering load.

    4. Others

    • Update drivers and firmware: GPU, NIC, webcam, BIOS - all should be current.
    • Update or reinstall Teams, clear its cache completely according to the “new Teams” procedure.
    • Test via the Teams web client (if you're using desktop app): if incoming video works there, the issue might be the desktop app.

    **Note: **Please understand that our initial response does not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution.  

    I hope this information is helpful. Please follow these steps and let me know if it works for you. If not, we can work together to resolve this.
