Bro im playing the game on my phone (Samsung a34 5g) and the animations are beyond smooth bro,just get a better system 👌
There is no actual 3D rendering in the game. It is 2D .png images taken of the 3D scenes, or .webm clips for the animations. If your PC is struggling with it then there is something wrong with your computer. Maybe your integrated graphics card having a hard time with playing the .webm files at such a high resolution and framerate. It is possible it is too old to keep up with large and demanding video playback.
