BirdDogICT 3 Posted June 30, 2011 I too was suffering from the "black square" problem in OFF using my ATI Crossfire 4890's if I moved my terrain/scenery settings above "3", i.e. I could run 5/3/3/5/5 all day, but not 5/4/4/5/5. But trying a little experiment the other day, i.e. disabling Crossfire, I am now able to run WITH OUT any "black squares" using the 5/4/4/5/5 settings. You could say that I have become a firm believer in not using Crossfire in OFF, now and in the future. Makes sense...although I have a single GPU, I've noticed some mild artefacting when using the Super-Sample AA that Crossfire requires. Most likely a driver problem.
