I don't like comparing these to Paper Mario because Paper Mario's graphic style is one big joke about everyone being paper thin. In my game, everyone is normal- I mention that I compare it more to the likes of the first Grandia game than anything else.
If you're curious, download the tester from my project log and see if it boots up on it. This would run on my Intel Integrated Graphics Adapter from an old Dell Dimension manufactured in 2003. The shadows are precompiled so that they run as fast as just being textures.
