GameHub- Cult of the Lamb settings?

My wife went and surprised me and she bought Cult of the Lamb for both of us on Steam Deck so we could play together. I’ve been using GameHub to play some of my lighter Steam games on my Odin 2 Portal and they have played pretty great so far.

I installed Cult of the Lamb in GameHub and accessed my Steam Deck save file so that’s great. What’s not so great is the performance of Cult of the Lamb. The FPS is around 6-10 mostly. Has anyone gotten this game playing in GameHub with better performance? I already had Cult of the Lamb running in Eden, but now that I’ve got COTL running on Steam Deck, I want to stick with that copy. I know I can always just use my Steam Deck, but playing on the Portal is sooooo much more comfortable. Any help is greatly appreciated!!
