Question Zoom - Latency, just my image, gets worse and worse lag

This is a video latency issue for only my own image, not others in a Zoom meeting. My video becomes more and more delayed as the session continues. After almost 2 hours, my own image (for me only, the other participants detected no problems, AFAIK) was delayed around 2 seconds.

Pretty new to Zoom, I've done maybe 10 sessions so far. Only in the last one did I have this problem. I'm just running the client, sign in with my Google account.

I was running 5.2.x until a week ago. The Zoom invitation I got last week said we needed ver. 5.3 to support some features that were going to be in effect. Checking my version, I downloaded the latest on 12/14, so Zoom client vers. 5.4.59296.1207. But I never joined that session last week.

So, yesterday I do a Zoom with family. I join on time, there were 2 or 3 of us, eventually as many as 7. The session lasted 1.5-2 hours. Every thing seemed fine for a while but after maybe 1/2 hour I noticed that my own window (i.e. the shot of myself from this laptop's camera) was out of synch. Everyone else's video and audio seemed locked in fine. My audio was fine, but my video was behind about 1/2 a second. I asked others and they had nothing to say concerning this, evidently nobody else noticed or had a similar issue. An hour later that 1/2 second had become 2 seconds. Strange as hell. I held up a hand and only saw my raised hand 2 seconds later. But my audio was in synch.

This laptop is fairly high end Lenovo P1 Gen 1 running 32GB of DDR4 and and about 15GB is free. I have a really fast reliable gigabit internet connection, am using 5ghz wifi.

What's the problem and how can I resolve it?

Camera software?
Huh? It's just the camera in this Windows 10 64bit 15.6" Lenovo P1 Gen 1 laptop.

I did a quick search yesterday... Lots of latency Zoom hits. Next time before the meet-up I'll try rebooting the machine and having nothing else running, see what happens.

Actually, next time the problem rears its ugly head open up a command prompt and perform a traceroute to the Zoom IP, and the a ping. You may find a hop in there that is causing the issue for you. Also when this happens again try pinging something like Google's DNS servers (8.8.8.8 and 8.8.4.4) and see what your access-side to public DNS is like.

The problem may not be you. Also keep in mind that video is a real-time type of traffic that is intolerant of packet loss. And I think most modern webcams are compressing video in order to lower the bandwidth requirements. The reason why you do not see other's delay is because it comes in on your downstream, which is usually considerably more capable than how you send you video upstream.
