Hey folks! I dunno if anyone is still trying to play Grotto in 2025 but I wanted to give it a play and noticed the framerate limiting is not working on newer graphics cards- as a result, the game's physics aren't correct and the game is unplayable.
I unfortunately no longer have access to the project files, but luckily there is a way to externally cap framerate and make the game work as intended!
The framerate is supposed to be locked to max 60FPS, which you can set in your graphics card control program.
If you are on an Nvidia card follow this guide: https://www.reddit.com/r/battlefield2042/comments/r5l0wb/limit_fps_using_nvidia_...
If you are on AMD follow this one:

Anyway, hope this works for you and you get a chance to play!
