personaly, i've tried MK:deception, ninja gaiden, halo 2, fable, and dead or alive 3. everything except halo 2 and DOA i noticed slowdown. it wasn't so bad in ninja gaiden, but i didn't play it that much, just a test run. MK:deception was a slide show whenever alot of particles were on the screen. that makes any stage with weather effects unplayable. some movies that cause big blood splats to cause slowdown, so the timing is off and combos are harder. fable remained pretty playable even with some stuttering.
on a positive note, the games are a little less jaggy (i played on an SDTV), and the texture filtering is better. especialy in MK deception. the game is bilinear on the xbox, and looks trilinear on the 360. also, the colors are a tad different, and it looks like there is better contrast overall on the 360.
