Hello, (I know I posted something in the other thread but it's probably better to focus on this one instead), I would like to try and help or at least try)
EDP other / RING and CORE in Throttlestop is normal, you will always see these.
ASUS have set the Turbo boost power limit PL1/PL2 to 175W, if the CPU does something, anything and spikes in load it will want to boost the P-Cores to the max. At max boost it's capable of attempting to use 175W so it's going to flag up as EDP limit on the cores. (it's current limit included too, IccA)
If you want to test, set the TPL PL1/PL2 setting in throttlestop to the max and it will decrease or stop. Alternatively limit the boost ratio on the P-Cores and E-Cores, for example and this is taking it to the extreme, tick the disable turbo boost option in Throttlestop. Now your cores should not hit the EDP limit as the default 175W setting will handle that. < All of this is normal.
The Ring EDP limit is something else and this is tied to a hardware limitation, throttle stop will always show that one active.
But regardless of the above these should not cause stuttering, do you have any videos of the problem happening whilst gaming?
Something I like to suggest is running a game in windowed mode with hardware monitor or whatever you use open so you can see what's happening at the same time. For example are the cores are dropping to much or are temps spiking... (I know you mentioned its fine but to see it in realtime is better)

1) And also the laptop chipset, RAM and nvme temperatures are they ok? PCH is the chipset which is unstable once you are at and over 90 DegC. This will cause stuttering too.
2) Your laptop CPU, has it always been running default settings?
3) And what happens if you play games with turbo boost disabled? (maybe slow / lower FPS but no stutters?)
4) Any changes to the RAM (memory upgrades...)
