They are on par with the Note, maybe a little faster. Don't underestimate the number of draw calls to render them...nothing in this game except for the terrain is solid geometry in a way that you would create it with some 3d editor. Everything is created at runtime out of simple beans that describe the position, orientation and attributes of an entity and then some view will be assigned, if that entity is visible. For the dungeon, each tile is a separate entity and requires up to 5 draw calls (torches and doors left aside).
