Have you bothered to try the different methods of crossfire in the AMD driver menu, or radeon pros? I have an R9 390X CF set up and I was happy to see the light flickering has finally been fixed, which im assuming that was AMDs doing as the game netted too little a return for them to spend money on updating it. Tragic really, its my favorite game base on the franchise. People just have bad taste. Would really like a solid alien isolation 2 launch. Its the steam version. CF with my cards is stupid overkill esp with OC, but you can use mods. In the future, it is said an englishman is working on releasing HD textures. Not going to take a performance hit for that, even if it mattered though. Driver: 16.8.1.
