On the ground missions the game constantly crashes when I have Crossfire enabled. Whenever I disable it, it's fine. The problem is, one of the pages somewhere on the STO site said the game would support the feature. What gives? Is it just a bug?
I got my computer built today and it runs other games perfectly. Using dual 1GB Radeon 4850s.
If you have Catalyst AI enabled, make sure it's set to basic instead of advanced (as the latter does not work with Crossfire). Beyond that, just make sure you have the latest drivers and I imagine it should work. My 5770s work without issue.
Some users have also suggested disabling dynamic lighting for Ati issues, so that might also be worth a shot.
