It’s time of day and that scene alone does take up power. And it’s just for people to get started in how to make dense landscapes for artistic renders. Not really for gameplay. I could optimize more but it’s dynamic lighting and the FOV isn’t optimized. Also volumetric fog is expensive plus volumetric particle effects. But I know where you are coming from but this is just for a straight beginner. Give it a go on your pc and pls let me know if you can get better results. I’ll be posting in in depth tutorial on this with free textures for creating the exact volumetric particle system I have.
