Video in Teams causes Surface Pro to overheat
I finally solved the problem by setting pl2 to 13 watt and pl1 to 25 watt in ThrottleStop. Pl1 time is 28 sec. ThrottleStop is in "turned off" mode and doesn't control Speed Shift epp (it is controlled by Windows) . Now my Surface works on 2.5-3GHz I don't have any throttling anymore.
I probably spent a year to realized how to correctly set it but now everything works pretty fine even in heavy apps.
P. S. So, in reality the problem is that some Surface software sets pl1 to 61 watt on Windows. For example everything works correctly on Linux from the box. So, ThrottleStop just correctly sets Pl1 limit and that's it.
P. P. S. Please, like my answer if it helps you because it may help other users (I hope)
I'm really happy to help! It is not clear why Microsoft didn't solve the problem by themself.
Small advice - please, don't try to improve performance dramatically or significantly increase turbo time if you don't have extra cooling like water cooler etc. Because even if you won't catch throttling immediately it will happen after several minutes/hours and you won't be able to disable throttling until the tablet cool down. This values 12/25 I took from official Intel documentation, I added 1 watt to pl2 but it doesn't make sense to increase them more without extra cooling. (I tested different configurations)
