I just bought a new pc with the AMD Radeon R9 390 in it. Im new to AMD so I just installed the programm like "Raptr" and installed drivers from the official website. Anyway i just started a game (Assassins Creed 2) and i experienced screen flickering similiar to what you can see in this video Assassins Creed II Weird Flickering on AMD Card Fix!! - YouTube
The problem doesnt appear normally when im in browser etc. I just tested this game yet. I did lower the settings and tried to desable Vsync but that didnt help. I hope that u can help me..
