First of all, I'll acknowledge this isn't necessarily Zoom's fault, but nonetheless, the issue becomes a major obstacle for people who (1) use Zoom all day at long, (2) who RDP into another machine, (3) who attend (this isn't limited to hosting and screen sharing, just attending a meeting can be problematic), lots of meetings, and (4) who have big monitors.

The issue is, RDP alone (before we even talk about Zoom) uses lots of GPU resources on the client side (to be unambiguous, client is my laptop at home running zoom, host is the desktop computer at my office that I RDP into.)

Add to that having a big monitor (or two).  For example, I have my laptop screen, plus a 32 inch 4k monitor over my built in video card, plus a 20 inch monitor at 1600 by 1200 only over an external USB-C to HDMI adapter.  I configured RDP to use my two external monitors, while the built-in laptop screen shows just the laptop's local display  (not the remote desktop) screen, while RDP is running maximized.  (Yes, RDP can do that with a little patience.)
Still before Zoom comes into the picture, if I create a small window, Notepad for example, position it within the smaller 20 inch monitor, grab the header area and zig zag it just a few pixels left/right/left/right, while keeping Task Manager visible on the processes page, I'll see RDP taking up 20 percent of the GPU engine.  If I move to the 32 inch 4k monitor and do the same, the GPU will hit 75 percent.

So... add Zoom to the picture, regardless of whether I'm sharing or not, moving a window anywhere in the RDP session overpowers the GPU/CPU in a big way and makes Zoom crazy/laggy in audio/video, and triggers a low resources warning.  (RDP GPU stops at 75 percent roughly in the 4k 32 inch monitor, and desktop window manager at 25 percent.  But basic math, 75 plus 25 = 100.   In the 20 inch monitor GPU stops at about 25 percent and Desktop Window Manager about 6 percent.  Scrolling but not moving a window hits the CPU/GPU hard, but into as hard as moving a window.   Working inside a window is again a little less of an impact.

At first I thought perhaps the external video adapter for the 20 inch monitor was helping, but after some experimentation with different screen resolutions, I feel confident saying it's screen-size, not video adapter, hitting the GPU hard.

I've read dozens of posts here and elsewhere, and experimented with one common piece of advice, overriding the host computer to use its internal video card, but that so far hasn't helped.   Similarly, I configured both Zoom and RDP via Settings/Display/Graphic settings/Options with different levels of priorities (power save vs. high performance.)  I even found a post about making sure the laptop can breathe easily.  Mine does anyway, but I di vacuum the fan area so it's dust free.  So far, nothing has made a big difference.

Anyway...   Any other ideas?  Any zoom employees who can at least forward this to product engineering?  My theory is it's too much competition for H.264 codecs, which RDP uses nowadays?  Could there be ways to compete less for the same GPU resources?

As administrator its part of my job to set up meetings, but I don't often go to them. I set them up outside of my office hours (I work at a church where the meetings are for volunteers who all have day jobs)

How can I set them up so someone other than me can start them? We have a pro account - but the next option up is very expensive for a church that has 3 employees and 8 volunteers...

when I'm watching a discussion between 2 or 3 participants, it would be really good to be able to level up their audio on my view, either automatically, or manually: Boost someone who is really quiet or quieten the noisy one that makes the quiet one hard to hear.

Is there any way for a viewer to assign local volume levels to individual participants?

Or maybe there are host options to do it for everyone?

This is something that has been driving me nuts for a while.  When I screen share a website, document or whatever, I am 100% always able to annotate it using my graphics tablet pen (XP Pen tablet and pen).  However, sometimes, when I client shares a website, a document, etc. from their end, my annotation option at the top of my screen is gone!  So I am unable to annotate on their screen.  I haven't collected enough information on the types of documents, sites, etc. that this doesn't work on, but I am wondering if there is something simple I am missing here.  I remember at one point when I would annotate, my name would appear next to what I was writing and Zoom told me the client has some control on their that will toggle on or off display of who is writing.  Is there some other menu on the client end I should direct them to, so that I can annotate their documents or whatever they are sharing??  I have asked them to look each time it has happened and they say they can't find any menus or toggles that would indicate they can enable that to allow me to annotate on their shared screen.  Hope someone can help.

Hello there! 

I'm curious if it's a bug or if anyone else is experiencing a similar issue.

My Zoom app that shows all of today's meetings is showing meetings as if they were scheduled for today, even though they have been canceled/removed from my Outlook calendar. I'm using a Mac, Version: 6.1.11 of Zoom.

I have set up a meeting with registration required.  All good until today, when I logged in to see who has registered and the registration tab is now missing.  The "registration required" is definitely selected, and I could see the registrations before.  This happened when I set up this meeting before, so I deleted it and started over.  Now it happened again.  What is going on?

Is there a way for administrators to collect information from hosts about the types of meetings they are doing. We want to know if this was a general meeting or was this a meeting where we provided a service or technical assistance for a client(s) to track for our records. We don't want to collect information if it wasn't related to a service provided. 

In general, we have information we would like to collect from the host about the meeting they are hosting in the zoom system. Is this something we can do in zoom?
