>As it is, "j" iterates in the wrong direction with regards to cache lines I always wondered 'what if' someone released Doom like FPS game in 1993 that required you to flip monitor on its side ;-). Both Ray-casting and Mode-X work best in vertical plane, while video memory access is only efficient when done linearly. Some quick back of a napkin calculations lead me to believe you could deliver 400x320 at the speed of Dooms 320x200. |
