I’ve done some speedtests on using a 2D tilemap or a 1D tilemap. I was under the assumption that 1D tilemaps were faster because it uses one less array lookup. I actually found that a 2D tilemap is much faster. More on this on [my blog](http://vipegames.blogspot.com/2009/12/tilemaps-2d-vs-1d.html).

I find it hard to believe that a 1D tilemap is actually slower. Have you guys had the same experience?
