hello, im writing a tile-based game in direct3d,and want to do smooth scrolling.according to this i have a problem,should i use orthogtaphic projection and make quads in 3d coordinates then rotate them to make them isometric or use transformed vertices,dont use ortographic projection and just give the real screen corrdinates? the reason i ask this is,if i use screen coordinates and create the vertices in real-time smooth scrolling is slow.But if i use orthographic projection and make translation of points it will be faster?cause they are processed in the pipeline rather then my translation code,in a for loop in screen coordinates? thanks

I'd say try both if it's not too difficult. Write a simple test for each. My personal opinion would be that doing it in the pipeline is faster, seeing as it's hardware accelerated, but I'm no expert on Direct3D. Well, for that matter, nor am I a novice.

There's my advice, as little as it may mean.
