Hey guys, as the title says. I have a ROG phone 5 with SD 888 and I'm getting terrible performance with AetherSX2 even though some of the latest updates have made improvements to the specific issues I'm seeing.
Here's a video of the issue happening to GamingDJ (on playstore version of AetherSX2):
A Xioami Mi 11X with SD 870 is beating the SD 888 powered ROG Phone 5.

And here's a video of the issue happening to me (vid was recorded with an older AetherSX2 version but happens with 2426 still, a bit worse on 2426 than on 2413):
In my video you can see I have the Aeroactive Cooler 5 attached, X-mode+ turned on and the phone is at 28C so there shouldn't be any thermal throttling. However big and prime core frequencies keep dropping between max and min, even though there's clearly more demand coming from the software side.

Another thing, I've tried tuning settings in Armoury Crate settings, here are the best settings I've found:
But still no 60 fps with them.

Additionally if I turn min CPU frequencies to the max, to keep the cores pinned at max frequency, the phone still drops frequencies to min, it doesn't run full throttle even though I specifically tell it to. Is this a bug on Armoury Crate?
It seems the throttling behavior is being too aggressive, even in cases when the phone is cool, actively cooled and under X-mode+.
