Using the latest Proton Experimental, I was able to get past the title screen.
The game stutters heavily when new shaders are being compiled, such as entering/running through a new area or battle, but runs quite smoothly at 60 FPS afterwards. No tweaks or extra launch options needed.
After upgrading to Proton 4.11-6, the game seems to run significantly better for me. It would never crash, but my video card isn't the best and I would have significant frame rate issues in busy areas like Metropolis/Stage 16 with older Proton versions (Like, sub 10-15 FPS). I now get 40-60 FPS in the same areas. Nothing has changed with my system, so it would seem some really good optimizations have been implemented.

Game runs great on Nvidia now. After testing older Proton versions and older Nvidia drivers, I can conclude that the Nvidia issue was likely fixed by Sega in the recent update they did (June 2023). Nvidia has said they've had the fix for months but have yet to push it to public drivers as of this writing. At any rate, the game seems to work now with little to no tinkering on various driver versions and Proton versions.
