Greetings to the entire community. A few days ago I installed the night Neverwinters 2 and its expansions, the top running, but after a few days began to give me problems graphics, letters, for example, the letters shake and the game gets very slow. Reinstall the drivers, but after a few days begins to do the same. My video card is a HD6870. In windows 7 the game worked ok. Greetings and thanks.
