Doing it MY way!
Well… it seems I ran into the classic SetData() problem on the XBox 360. It really is THAT slow! So my new improvements (multithreading) didn’t do anything for the XBox. I then changed the code to create the frames on a seperate thread, and THAT improved performance. Now I’m up to about 42 FPS (max) … Read More “MPEG Decoding update” »
