Its an improvement over its predecessor with a few framerate hiccups, hopefully these can be addressed before release. Bayonetta 2 is another Wii U game with no AA and poor anistrophic filtering, it seems that no dev will bother to use the 32MB esram for MSAA which is a shame. Lastly its been confirmed to be 720p so those unreasonable 1080p rumours can be put to rest.

Can someone explain to me what the 32MB or ESRAM is used for? I've seen it a couple of times but I don't understand the technical aspects of it. How can it be utilized? How can it improve the game? 

Basically, the system has 1GB of main RAM for storing the data it's using, but some operations need to be accessed and worked on more quickly than others, so it has a 32MB bank of ultra-fast RAM for this purpose.

Basically, it makes certain techniques more efficient, or simply possible where they may not have been using just the slower main RAM.

Ahh okay, I understand now thank you.
But how does that help with anti-aliasing and anistrophic filtering?
