I'm sorry, this is an issue that's appeared since the engine we use updated. Unfortunately, it depends on the device for what's going on and I can only guess what needs to be changed to make it run better. Here are the usual suggestions, though none of them are guaranteed to work.
Updating graphics cards and/or changing their settings. If you have multiple cards, switching the one you're using.
Updating drivers to the latest version. And going out of your way to try making them update rather than leaving it up to the device to register on its own that an update is needed. Sometimes updates aren't pressing enough to be reported automatically but can still be done.
Turning off the game's animations
Turning off "Game Mode" if you're on Windows 11
Enabling "Optimizations for windowed games" Windows 11
Verifying the integrity of the game files through steam
Playing in windowed mode, or trying to reduce the size of window mode
Creating a desktop shortcut and launching it from there
If there's something we can do about it on our end, we'll try to make that happen!
