Runs well on ROG Ally X but TANKS on my eGPU

[bigkurz]

Add me to the list of people having a bad time with the fps on this game…but ONLY when i dock into my eGPU.

ROG Ally X
Razer Core x Chroma eGPU dock
Nvidia 4070 super installed in my dock

Playing directly on my ally x, i can basically play 1080p 60fps constantly on medium settings. Looks great. Runs great. Good time.

But when i dock, performance takes a complete nosedive. And this is ONLY happening with this game. For comparisons sake, i booted up both p3 reload and p5 strikers and can run both games at 4k 60 on my setup.

On p5r, my gpu usage instantly jumps to 100% when im in game, while the fps is very inconsistent jumping 20-40s. The fps does not change when i drop the resolution. I’ve tired everywhere from 900p to 2160p. The cpu usage remains reasonable, the gpu sits at 100%, and my fps doesn’t change.

I am bewildered as to why my playing my rog ally x on medium portably i get 1080p 60 but docked into a 4070s my fps tanks.

And to reiterate, this is ONLY happening with persona 5 royal. Every other game runs fine.

I’ve read so many threads on this games performance and none of the tricks have helped me. My pcie lanes are fine. I’ve messed with priority and cores in task manager. I tried the dxvk stuff (and it made my game worse, not better). I watched a few videos about Nvidia control panel and tried out every one of their recommendations.

And to address a common recommendation, i KNOW it’s not running off the ally APU. it’s outputting to the hdmi attached to my card, Nvidia activates when i play, and even if it WAS running only off the ally chip my performance would be better anyways.

I guess my solution is just going to be to NOT play the game docked. But that’s wholly unsatisfying and i would like to figure out WHY my game is broken / if there’s anything i can do to fix it.

Help appreciated

In case it matters to anyone who comes across this post, I tried out Persona 5 Royal on the XBOX PC launcher and had this same behavior. Definitely frustrating but i guess i just need to move on and play portably. But please if anyone has any insight im all ears (eyes?)
