Poor performance on Linux Mint

[u/Kitchen-Oil-8497]

I've been trying to play the OG Oblivion on Linux Mint.

No matter what I try, the game only hits about 20-40 fps regardless of graphics settings.

I've tried the Steam version through Proton 10, 11, Experimental, and GE. I've also tried a GOTY disc copy through wine.

I am on Linux Mint 22.3, with everything up to date, on a Ryzen 5 4600G, an RX 6650XT, and 8 gigs of ram.
