Software: had when using the glasses twice Bluescreens, so total system crash (probably due to driver errors). Once upon a time so blatant that the operating system is no longer allowed to start and had to be reset. Both male ever at the start of WoW ... then again. However, I think that this is an isolated incident - random / bad luck just.
Otherwise, the 3D mode is sometimes activated when Benq, although the game is over, damn annoying - I guess this is due to the software that controls the wrong.
Games: Many items are uncomfortable to play, because some things unfounded right in front of glue, rather than to place in the correct position in 3D. Other bizzare effects occur, especially in post-processing and Shader effects or Mulitipassrendering. By this, of course, the implementation of the games is to blame, but in the end it is how it is in fact often unpleasant to look at and unrealistic.
The best counter-example is World of Warcraft - here it just makes a lot of fun to explore the world in 3D, no wonder as the game 3D mode also explicitly supports and even provides specific internal settings. Is only a pity that the (graphic: P) water quality needs to be turned down, but repays to cope.
Bottom line, it is absolutely worth the experience but everyone must decide for themselves whether it is worth the glasses
