Hello,
while gaming i am facing frame drops after few minutes, GPU clock drops from 1400Mhz to around 400-600Mhz.
Checking CPU and GPU temps they are not high (CPU is around 75-80 and GPU 75-83) so i don't think it is due to thermal throttling.
However i realized that the frame drops appear when the GPU wattage drops, and i don't understand why this happens.
In the first minutes it works perfectly and it is at 50w, then it drops to 25-30w.
I am using January Blue drivers and this happens with any driver i tried (also the stock ones).
I am using Throttlestop to limit Turbo Boost Long Power Max at 30, i have enabled SpeedStep, C1E and Speed Shift.
By checking GPU-Z i see that Memory Clock is stuck at 1472, shouldn't it be dynamic?
Thanks in advance for your help.

I suspect what is happening is that the VRM is getting too hot and limiting its power delivery to both the CPU and GPU. So while the CPU and GPU are cooled off by heatsinks and the fans, the VRMs are just air-cooled and need time to cool down. Unfortunately I haven't seen any good way to really solve that. I saw one person put thermal pads on the VRMs which the side effect of transferring the heat to the outer case. I didn't want to try that.
I've come to the conclusion that Apple designed for video editing (bursts of power) more than for gaming (long term sustained power). I'm looking into cloud gaming options at this point.

Thanks in advance for your help. Similar situation. By some miracle, I managed to eliminate the interrogation after turning on this 48 hertz. All day I played in the most loaded projects, including RDR2, Metro Exodus, BF5 at stable 48 fps! Metro Exodus even had ultra settings and fps was stable! This is double, since I know that this is a very demanding game and sometimes I have fps dropped even at 1080ti. I thought - cheers, the problem is solved. And then Windows decided to automatically update. ((( Everything returned. I deleted the updates, but this does not help. This is ridiculous, the temperature is 65-70 degrees, the GPU thinks that the load is weak and reduces the frequencies, but they should stay at 80 or 90 degrees, and then only decrease. I lost 3 days to resolve this issue. I see that the problem has been familiar since 2012 and there are successful laptops that have been agitating the load and frequencies for a long time and not. Very dissatisfied with this company. I will only buy with a check for throttling in the bootcamp for at least 30 minutes!

They probably didn’t solve this problem, but how can I explain the fact that I managed to cut high frequencies all day, if the problem is not solved? |

I think I understand what we need! Frequencies are reset when the load on the video card becomes 99%. It happens to me after 2 minutes or after 8 minutes if the laptop is completely cold. Need to somehow limit the load on gpu at 90% Any ideas? MSI does not work for me (m5300)

I managed to solve (partially) the issue.
I simply set the multiplier to a lower value (such as 27-30) in ThrottleStop and this made the CPU run much cooler.
Maybe i'm wrong but it looks like limiting the wattage on the CPU does not work well since there are a lot of fluctuations even at 4.8Ghz when it uses single cores, leading to high temperature.
By limiting the multiplier there are no more fluctuations and this helped a lot.
I don't know if it is related to CPU temperature or some other sensors but by using this trick i managed to reach quite good results.
Personally i have enabled Speed Shift 1-30 and it works well.
