Ok, so I got SWFU2, and the characters along with some of the surrounding elements are really dark or invisible. I have all current drivers for my GPU and so on. Also no change in contrast or brightness helps. I have tried all graphics settings with no success.
CPU: AMD Phenom II X4 970
RAM: Mushkin DDR3 1333MHz 4GB (2x2GB)
GPU: ATI Radeon HD 4770
PSU: OCZ Fatal1ty 550W
I'd honestly suggest looking for support on their official forums. Considering the game was literally JUST released, this could easily be a bug in the game. Keep in mind, this is a Console Port, so there's bound to be problems.
You could definitely try using different ATI driver versions to see if that fixes things. Sometimes different versions cause or fix certain bug type issues with some game titles.
