Poor performance from a high-end build?

[Tanukki]

If you get enough creatures or players moving around on your screen, the framerates will tank. Mostly due to dynamic shadows, I imagine. Little bit more optimization in this area would not hurt, this game is pretty and all, but an MMO is supposed to be accessible. You shouldn't need enthusiast hardware to run it smoothly.

Here's some benchmarks BTW: https://docs.google.com/spreadsheet/ccc?key=0AnFkM1_JharvdGlIc0dwMmcyWDVoR1gzTGp2UlJUVmc#gid=0

The game does appears to support multi-core setups quite well, but the gains from hyperthreading (i7 vs i5 processors) are not that significant, as is typically the case for games.
