ToME: the Tales of Maj'Eyal

In my experience, the performance under linux is much better than under windows. Has anyone done any profiling of the various platforms? I'd be happy to look into it, but I'm curious if anything has been done already.

It used to be worse for me (in linux vs in windows) like a year and a half ago, but then it suddenly improved. I'm guessing it was something to do with the particle effects?
