It was always smooth (no lags or so) - the lowest fps I got was 28, usually more than 50. (Pentium D @ 2,8 GhZ, nVidia GT9600, 3 GB Ram)
All in all it is nice, but I would like to have some variation of the textures and maybe some particles? The water did not really match the scene, as this was looking so "now days graphics" and the rest older ^^
