Given that game has been marked "Playable" years before your CPU has seen its initial release, and that there are no notes on its Wiki page, I'd expect it to run essentially perfectly out-of-the-box, short of some regression causing issues.

You should give it a retry sometime if you can / want to. That said, I should probably let you know that the community can be slightly hostile, and they will ask you do the legwork if it's not a misconfig but a suspected regression (they'll want you to bisect the build where the choppiness appeared). You'll also want to run the topic by the volunteers in the #help channel on their Discord before opening an issue ticket on GitHub, as their GitHub issue tickets are not for support, only for actual issue / feature request tracking.
