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) against the old 24-27’ish frame rate.
Next up is trying to improve picture quality using shaders! More on that later!
Just got my XBox 360 back from repairs and it purs like a kitten 🙂
Motherboard and DVD drive was replaced so I’m ready to continue decoding MPEG streams and the like. I will (hopefully) return with an update on the framerate issue later. I’m hoping the new otimizations pays off.
Multithreading the MPEG decoding process, I’ve managed to increase the performance of the decoder by ~28.71%. I’m hoping to squeeze another 2-3% out of the decoder on the cost of more memory consumption.
On another note, just got word from the Microsoft repair center that my XBox 360 already is on it’s way back… impressive to say the least! They only had it for 3 days before fixing and returning it. Looking forward to getting it back so I can test the new code 🙂
