TiledMap - edges low quality

Hello,

Im trying to create 2d paper mobile game based on tilemap with static camera covered whole map.
I want every triangle to be perfectly straight, but i can not get it. I’ve tried all settings for texture, tilemap and camera and always some triangle must be poorly rendered.
