I've been looking at how to run multiple WUs on my GPU with MW like I do with Einstein. I've copied a bunch of people's app_config and it doesn't change anything: I still only run 1 GPU process at a time. Einstein required me to do it through the website (app_config didn't work by itself until I changed my computing preferences), but I don't see a similar way on MW to do it. My app_config is below, though I've tried a bunch of different things:
name=milkyway, milkyway@home, Milkyway@Home, MilkyWay@Home
concurrent=0, 1, 2, 5, 10, 50
gpu_usage=0.5, 0.25, 0.125, 0.1, 0.05
cpu_usage=0.5, 0.25, 0.125, 0.1, 0.05

Not every combination, obviously, but a bunch, and they all result in me doing a single GPU WU.

<app_config>
<app>
<name>milkyway</name>
<max_concurrent>50</max_concurrent>
<gpu_versions>
<gpu_usage>0.125</gpu_usage>
<cpu_usage>0.05</cpu_usage>
</gpu_versions>
</app>
</app_config>

Here is what I have

<app_config>
  <app_version>
   <app_name>milkyway</app_name>
   <plan_class>opencl_nvidia_101</plan_class>
   <avg_ncpus>0.25</avg_ncpus>
   <ngpus>0.5</ngpus>
  </app_version>
</app_config>

Replace opencl_nvidia_101 with opencl_ati_101 if you have an AMD card

After saving, hit "read config files" as they need to be reloaded

Options -> Read Config Files in the manager in advanced view

Tried it and there's no effect. I'm really starting to think Milkyway doesn't want me to use my 3090.

Where are you putting the app_config file?

Mine is in the default location of C:\ProgramData\BOINC\projects\milkyway.cs.rpi.edu_milkyway

If you went next next next in the installer it should be there, otherwise locate your data directory and put it inside the project directory. Once you do that restart the client or hit read config files

Could you post the last 10 lines or so of the event log in "Tools" menu "Event Log" right after doing the following. Make sure you don't have anything uploading or downloading in the "Transfers" tab (wait until it's all clear if you do) and then re-run the "Read config files" from the "Options" menu.

Another problem for some people is the system auto adds '.txt' on the end of the 'app_config.xml' file name meaning it won't work in Boinc. Another possible problem is you aren't using a text editor to make/edit the file, a word processing program will add other junk to the actual file again making it unreadable by Boinc.

And I only edit using Notepad++, and the file extensions, where appropriate, are .xml. The log didn't show that it's reading the app_config file at all.

I thought to check the log after restarting BOINC to see if that provided any illumination:

You're sure that the app_config.xml file is inside the project directory?

The directory since you're using default is C:\ProgramData\BOINC\projects\milkyway.cs.rpi.edu_milkyway

And I think the app name should be "Milkyway@home Separation v1.46"

Well, poop.

Yep, that did it. I thought that file went in the main directory, not the individual project folder.

No the app_name is milkyway.
You can always check the app_name in the client_state.xml file. It is not the "friendly name"
Also if you put in some bogus name for an application in your app_config.xml and re-read config files, BOINC will report the error in the Event Log and tell you all the known application names it knows about.
You can find the proper app_name that way also.
<app>
<name>milkyway</name>
<user_friendly_name>Milkyway@home Separation</user_friendly_name>
<non_cpu_intensive>0</non_cpu_intensive>
</app>

Worked for me until I went to RX 6xxx cards which can't run the GPU Sep WUs because the app still has a pre-OpenCL 2.0 (depreciated) command in it to get memory for a 'command que'.
