It seems like the Ninja Gaiden game for PS3 is full of jaggies, you can look at the picture taken from IGN below. I know it's the full version yet, I hope the final version will be cleaned up, hate to see jaggies on the PS3 even though I'm kinda used to it for my PS2. It hurts our eyes if it's in HD and full of jaggies. I hope the hardware is capable for full screen anti-aliasing without getting a performance hit.
