When on the skills selection screen and i click on a skill (either to put a point into it or to view the description) the game freezes for a few seconds. While the game is frozen for that moment, it shows the description of the skill that is in the top-left corner (i think that's the summon undead skill) than it finally gives me the description of the skill that i clicked on and the video demo of that skill on the left. the tiny videos that show the skill being used do play without any problem.
in any case, clicking again another another skill causes the game to freeze again for a few seconds before it shows me the skill description and its demo. this thing happens every time.
if i leave the skills screen and return to it, whichever skill i click on will always show the skill description of summon undead until the game unfreezes.
other than that, the game runs great on my machine. the game's intro video played very well with no choppiness.
