A post on the Bohemia Interactive Forums asks for help with a problem causing a watery image degradation in Take On Helicopters, Bohemia's new flight simulator. As it turns out this can be the result of using a pirated edition of the game, as Bohemia explains this comes from their "unique anti-piracy countermeasures," also noting a demo for the game is in the works. Here's word:

Bohemia Interactive deploys various antipiracy countermeasures in its titles and Take On Helicopters is no exception, some users have reported morphed/watery image degradation (see http://forums.bistudio.com/showthread.php?t=126991 ). The original version of Take On Helicopters does not suffer from this degradation of visual quality. Piracy is a big problem for Bohemia Interactive, as an independent PC developer, and we're trying to focus our support as much as possible towards users of legitimate copies. Counterfeit copies of our games may degrade and, moral aspects aside, we certainly recommend only playing the original version. We have a free public demo version of Take On Helicopters in the development pipeline for those that prefer to test it before buying.
