See my other thread on P73 performance issue;
GPU will go to limp whenever laptop is moved, touched or else;
Temp fix was to unisntall Lenovo's power management sofware / drivers; Few items;
Nothing is lost (really), laptop works as it should

The "moved" issue looks like the performance setting of Lenovo Vantage. You should try using the "Enterprise" version of Lenovo Vantage (see here: New version of Lenovo Vantage (10.xxxx) is missing features) and:
Sorry, I'm not in front of my machine so I cannot be precise at this time. Search this forum for more info.
Edited the post with the precise information.

I have just seen your reply, and thank you very much for taking the time. I actually gave it back for a full refund, I will give it a shot probably next year with P54, and if they keep with the same QA issue, I will disable the whole Lenovo from my list.

Another 5c ...
Such throttling behaviour may occur due to insufficient / faulty power supply;
This is what would happen if you hook up P73 with RTX5000 with 170W PSU instaed of 230W and load it up (booth CPU and GPU)
GPU-Z will read both power/thermal, GPU will drop to 300mhz every second or so
In many cases laptop will tell you that is powered and is charging just alright ... there will be no warning
With real thermal throtting (one caused by high temp which is 86C for P73 it seems, not sure what it would be for P53 in question) it should only present thermal as a reason for cap;
I did a test run with 170W PSU and it would go limp way below 80C and the reason stated would be power / thermal; With 230W everything is cool;
Also one can install RTX 2080 mobile driver from NVidia; This one will work but will push frequencies much harder; In my case, 5 minutes of PUBG will cause thermal throttle (86C), yet still smooth and playable. With Quaddro driver frequincies will be about 10% lower, temps will settle around 82C and there would be no throtting; It is possible to avoid throtting and squeeze a little extra performance with RTX 2080 driver by using those external usb-powered fan sucker thingies ....

I finally got my computer working properly! My P53 is able to run VR no problem now, and Apex Legends at max settings on 1080p I am able to run at 90+ FPS. Things I did to fix the issue:
1. Fresh Install of windows 10 (this initially did not change anything)
2. uninstall/disable the lenovo power management, PM, thermal solution drivers
3. These drivers kept reinstalling themselves on restart and I could not seem to prevent this. "disabling" them appears to keep them disabled after restart, but I also downloaded "Autoruns" and unchecked all the lenovo items. I'm not 100% sure if this helped solve this issue.
4. I set the display to only run on the dGPU in the bios
5. I installed an older version of the RTX 4000 driver. I am currently using driver: R430 U7 (431.94), released Sep. 25, 2019
I have not installed Vantage or any other program. Using GPU-Z, my GPU speed and clock speed both hover around 1500 Mhz now, where as they were locked at 300 Mhz or 100 Mhz respectively before the fix.
My computer is the i9, RTX 4000, 32GB ram, 4k display. I am currently running the display on 1920 x 1080 for SolidWorks, but this should be unrelated.
Special Thanks to agazpp and FreedomReapr in this thread and the other one for all the help and suggestions!

So I haven't completely solved it yet, but I haven't had (or taken) time to really experiment as my CAD and buisiness stuff has been working fine. I know the game is still dropping to lower frame rates; so still pretty frustrating.
I'll run through the steps you've taken and see if that helps.

I have recently purchased a P53 with nVIDIA Quadro 2000, i7-9850H CPU, and have had issues with external displays dropping from 60 fps to 20 fps when I close the lid and only use external monitors connected to a USB-C gen2 Lenovo dock, both at 60Hz. I have sent it in twice for repair and they did nothing to fix the problem. Windows settings are set to do nothing when lid is closed. In the nVIDIA control panel, I recently set the PhysX to GPU or CPU instead of the recommended auto-select and the issue goes away. Any ideas if this is good, bad, or if it does not matter would be appreciated.
