Hey Hamstray,
I have the asus G15 3070 (GA503QR) and i have the stuttering issue also. i tried everything i found on reddit: deleting a particular folder from armory crate, changing the wireless power saving mode editing the register to no avail. the problem persisted horribly and then is when i found out about this fTPM issue that AMD has acknowledged in an statement. It seems they won't have the code ready until May but here is something else i tried and it has improved the stuttering (particularly while on battery and simple tasks like writing code and listening to music). download the latest mediatek card drivers from here (search google: 'asus forum mediatek driver' and click on the rog asus forum link to find the latest [this forum won't let me post the link as a new user]), then delete the ones installed in your G15 including previously saved drivers(there is an option to 'check' while you are uninstalling) and then install the one you downloaded from the ROG forum. This problems seems related to some sort of latency issue between the processor and the operating system using fTPM which is also aggraviated by really bad drivers from mediatek part. This will not solve the stuttering during demanding games since i still experience them while playing Jedi Fallen Order but at least it will hopefully address the absurd stuttering during video and music playback particularly on battery. This is still present while on AC power and using Zoom with screen sharing, the processor can't handle the load with the timings and starts stuttering, you can go into your Nvidia settings and select dGPU to execute Zoom and/or any other application you use and think your proocessor is struggling with.
I stand with you on this issue and i hope ASUS listens to our requests and implements a solution once AMD provides their own to all vendors. This is a pretty widespread issue and not only on this laptop but for many desktop users as well.
btw, are u also experiencing the random touchpad lag?? like 1 sec behind movement?
Cheers
