ToME: the Tales of Maj'Eyal

As the title says, I experience so much lag in Daikara and the Tempest Peak that they are unplayabl. To a lesser extent, this also happens in the Orc Prides. I suspect it has to do with elemental spells/abilities since many of the monsters in those areas employ them.

Also, on the occasion that the game crashes in a dungeon, it is still very likely to lose memory of the world map on reload.
