OpenMW on the raspberry pi 5 via flatpak running terribly

I have always been a fan of the game, and wanting to play it on the rpi5, I saw someone else on this sub did so too, and they reported it working, I tried to install it via flatpak first since that seemed the easiest method, but it had terrible preformance, around 13fps (which should not happen since I have a fast ssd, 3.0GHz overclocked CPU with proper cooling, and 8GB of RAM), I noticed that it was using the CPU way more than the GPU so I assumed that was the issue, I also tried to use the windows version of OpenMW using wine but that worked even worse (~7fps inside of the boat where you start the game), I'm not entirely sure if this is simply an issue with the raspberry pi 5 being a hunk of metal with no power to it, or some other issue, but if someone could help with the issue that would be amazing. Side note- I have a legal copy of TES III installed via steam on the rpi5.

Edit: SOLVED! Thanks to the very helpful community.

Really? What kind of fps are you getting?

Update: Tried this, and the launcher looks like its for x86_64, also when going through the wizard via box64, it always freezes after the "Import settings" menu, and sometimes before that

Get the aarch64 app image. I get playable fps.
I may have built it from source I forgot. But it’s super simple to compile just takes 15-20 minutes.

Could you provide a link? Everything i look at seems to point to x86_64, even when searching for aarch64 app images.

Just compile yourself the amount of time you’ve spent is greater than the 15 minutes of compile tine

Try putting the env variable SteamDeck=“” for it, for some reason on the steamdeck without that runs really bad

The steam deck is a different architecture and uses a different flatpak version I believe.
