Huehnerschander: Not THIS slowdown... It dies even bcuz of simple Draw methods... Not to mention StretchDraw. And of course it can't even display any Alpha blended thing... But I have a switch to turn those off, so, point is that it just can't draw simple surfaces in normal speed.

Robert: I do know those don't support everything, but goodness, simple Draw-s? :\ Maybe the fact that I'm not only using surfaces with width/height of 64?ó128?ó256 and the like?
Z-order, sorting... sorry, I'm not experienced enough for that yet... And I'm talking about something 2D...
