Ok, considering the number of report of this GPU throttling issue, I think the problem is real. This is in other topics of this forum as well. I'm even wondering how it's not impacting every bootcamp users having a 16" MBP. How do we proceed ? should we create a new reporting topic gathering reports and videos of every users to send it to apple support or macrumors ?

So now I am playing with GPU settings through MorePowerTool, if I find something decent I will let you know. Did using this solve the issue? Also what are your settings please

Also what are your settings please Using the bios settings atm but I just lowered the power limit from 50W down to 30W - it is giving me 400-500MHz with 99% utilization. Temperatures dont go above 80 and hence GPU is not throttling - on paper these are really low but at least I am not getting affected atm. I ll try to change thermals/increase the power limit slightly and see how it works afterwards

The hangar isn't a demanding part. In-game matches and Test Flight are were more demanding. When showing many objects on the screen, GPU clocks up anywhere from 1000-1282MHz. Utilization rises up to 99%. This game uses nearly the entire 4GB of VRAM I have during an extensive gameplay session. I already have MSI Afterburner and RivaTuner Statistics server installed. Those allow me to put an overlay. This was an initial test that nearly lasted one hour. I will have a real one with Discord voice chat and screen recording at the same time. Well then that’s a good result! What did you do? Did you take it to the Apple and they changed thermals? Or was it a new purchase? I am confused but still glad you are running smoothly And also what is the maximum temperature that you see on your GPU/CPU after 10-15 mins of play like that? Interestingly what I have figured out with mine is if I power limit GPU from a fresh restart to 30W I have never seen a BD Prochot and highest temperature for GPU was 78 - but the clock speeds were 400-500 MHz still low. Now increasing power limit I know 35 watts throttle so it has to be around there. Once there is throttling GPU has the control over my computer This was just a repair. The document only states that there is a top case replacement. I also requested to clean it off all the dust. Nothing was said about changing thermal paste. After 10-15 minutes in a 32-player match, the CPU maxes out at 65-70C in most maps but the demanding ones. In the most demanding maps, the CPU temperatures are 70-75. The GPU is usually 5-6 degrees lower than the CPU. There is no significant difference in temperatures when sharing my game screen on Discord. I did not set any power limitations to the GPU. I do not know how to set them on a Vega 20 either. I am also uploading two videos as well as the worst case scenarios I captured.

I used MorePowerTool for the first time yesterday and it worked perfectly. I haven't read through the whole thread, but are you just not restarting your computer after applying new MorePowerTool settings? All I did was change the TDP max to 40W, the frequency range to 800MHz min and 1100 MHz max, hit "Write SPPT", and rebooted. Then in Afterburner while gaming I can see that I maintain a steady ~1000Mhz clock without ever breaking 80C GPU core. Note that I am also using ThrottleStop to set long and short power max to 25W. While gaming I see the CPU hover around 15W and 75C. Yeah, the problem with that is it is very game dependent. Apex Legends is very GPU dependent game and 1000MHz cause it to reach 85-90 degrees with 3GHz CPU and I throttle. I even tried it with 800MHz max - where those are ok at first all my frequencies fall down to min which then triggers BD PROCHOT. Can you screenshot your morepowertool pages and paste here. I can copy paste all of them - maybe other parameters are causing it ? (I doubt it but I am hopeless and rdy to try anything) Two sets of screenshots attached, one "before" (when freshly loading my BIOS) and one "after" my changes. I just played a couple hours of Doom Eternal and it was rock solid, no throttling. Another potential factor is that I'm playing connected to an external monitor with the internal screen turned off via Win+P hotkey. Having the internal screen off may help stave off throttling by significantly decreasing power usage. I'm using Blue January 20.1.2 drivers. Also just opened up Doom Eternal again with MSI Afterburner open. I'm sitting at a steady 99% GPU usage, nearly full 4GB VRAM usage, 1100-1200MHz GPU core clock, 40W GPU power usage, 75C GPU temp, 3000MHz CPU clock, 16W CPU power usage, 70C CPU temp.

Posting photos of above in-game Doom Eternal performance.

While a combination of all of the above has initially me given promising results, this does not completely eliminate the possibility of thermal throttling. Here are a couple videos of War Thunder gameplay with the overlay. These are in two lesser-demanding maps. The initial temperatures hover at 60-65C until enough heat has been generated inside to raise it to 70C. After 3 hours of playing War Thunder, BD Prochot kicked in. A few minutes before the power throttling occurred, the maximum temperature reached was 75C on the CPU and 67-70C on the GPU. Never at a single point did the machine's processor reached 80C as reported by other users prior to the throttling. Enough heat was produced between the Touch Bar and the display, making it throttle. It is not the temperature itself but the resulting heat over a period of time that determines whether to trigger BD Prochot. This incident of throttling occured at an ambient temperature of 25.55C. Above 75F without sufficient air conditioning, there is a risk of MacBooks thermal throttling after a certain period of time running Windows games. On the bottom left, the framerate as a result of the idle GPU is shown.
This is a screenshot of another incident of thermal throttling right before the GPU becomes idle. The GPU becomes idle once the processor is at 900MHz.

Waiting for the MBP 16-inch to arrive, and am really worried about throttling problems in bootcamp.
Glad to find bootcampers discussing this topic.
Has anyone tried booting wintogo from an external ssd? and did that make gaming performance worse?
Thanks.

I used windows with this laptop via a Samsung T5(?) external SSD, and saw no impact in gaming performance. Productivity, app launch times, and startup times are of course impacted by slower read-write speeds but if you are just gaming on bootcamp I doubt you will notice it once you have the game fired up.

Appreciate it I'll do my part by doing some prolonged gaming sessions to see if i could recreate the throttling.

This guide worked for me to get windows to play nice with the T2 chip since external drive means no bootcamp: medium.com/@transferx23/install-windows-10-on-an-external-hdd-or-ssd-with-boot-camp-under-macos-catalina-10-15-e0e315f2d48d

I now have OBS Studio recording the entire screen in-game if anyone still needs me to produce more video footage.

I now have OBS Studio recording the entire screen in-game if anyone still needs me to produce more video footage. Yes please. As many videos as you can, I have spoken with Apple Care. They have opened up a case for me. But mainly they can’t help with it as it was in Bootcamp. They were asking me if I can generate the same in MacOS. The problem is they are undervolting in MacOS and it is not that easy. But I ll escalate this issue with them and if we have a lot of videos - it would help me prove my case for sure. For me as of now - throttling is still a case and BD PRochot is becoming active not because of CPU or GPU but something else. They were saying throttling was normal which I hugely disagree as some of us have really good temperatures. Secondly, which is the main issue - the GPU and CPU never recovers back unless the game is quit and even though the temperatures were below 70C.

I agree their answer was not helpful.And this throttling is not normal at all. You should have better follow up from the official AMD bootcamp driver team. I did not find their contact email though ..
