Heya,
I booted up Galciv 3 as soon as it came onto my PC with sub FTL speeds. As soon as I booted it up, I noticed very heavy GUI flickering (making the majority of things unreadable).
I fixed it by going into catalyst control centre, and turning off AMD Dual Graphics mode for galciv 3. Now the game runs just fine here! Time to start a match.
