I think in photo mode the games does something to smooth out the jaggies and shimmering which are unfortunately all over the screen during gameplay.
Even the visuals can be inconsistent; sometimes they look good and sometimes they look terrible with low res textures on the stages, dirts and effect.
Yeah, a visually very inconsistent game. With very high highs and very low lows. You can often tell the game was rushed and many corners were cut. A far cry from the extreme polish and love to detail of older DOAs.
