This is a 3D model from Sketchfab, which has a very high poly count, and many many tiny polygons in areas of detail like the eyes, face and hands.Here you can more clearly see the incredibly high level of detail that has gone into this model. The model has 165.7k quads and 331.3k total triangles. This would not be efficient for running and rendering in realtime for a game engine. The more economical the mesh density, the less taxing it is going to be on the machine running it. This would would be less problematic for an animation where the rendering does not need to be rendered in realtime.These are some other models that I found, which have a much lower complexity and lower mesh density, which are much more suitable for realtime rendering in a game engine as the efficient modelling is less taxing on the machine.
