2D TileMap rendering and optimization

Hi everyone! Quite a noob here… I was trying to create a 2D survival game, with an automatically generated terrain (with perlin noise function) that uses the tilemap feature. The problem is that when I create a 500x500 unit map (which i consider small) i get 13 fps… I was wondering if there is a definitive solution to this or a best way to proceed, because even searching online i couldn’t find any helpful resource. Do problems like this require a specific script or there is a general solution? shuold I create a texture (not really familiar with those and meshes)? What’s the best efficient way to do this? I’d be glad if someone could give me some directions :smiley:
