While I haven't played this new version myself yet, I've been seeing multiple reports of this issue over at RetroAchievements and wanted to make sure it was reported here.

EDIT: Looks like the dev not only fixed it up already, he uploaded an old version just for us RA users. That's a quality dev. Might have to see about buying this one in support.

It's not an engine issue. It's an nvidia prime issue. Having just spent a day doing terrible things to my system to try to fix vsync in general, it now works just fine in this game.

Oh hell... it was -because- of Vsync. Turning vsync off returns it to normal speed. With vsync on, it goes nuts. I'm not entirely sure this is an issue with your game given that, nvidia cards in dual graphics laptops can have certain issues with vsync if the intel card isn't active at all. Still, I guess it's worth being aware of?

For some reason, the game runs too fast (Mint 19.2). It's playable, but all the animations are ridiculously sped up. Not quite sure what that's about. Framerate shows a solid 60 fps.

EDIT: Try testing the game at 120Hz. That's probably the issue.
