The Radeon 5770 is a new Directx 11 card, but what graphics driver do you use?

I have the Radeon 5850 and use the 9.11 catalyst driver so far. And the game seem to work nicely. I have noticed some kind of flickering of the image inside the binocular when looking at a ship sometimes, I suspsect this flickering might be something with the game engine though.

I installed latest drivers form Ati website.I guess it is 10.2 catalyst
It is very annoying not to be able to turn on environmental effects and shadows
because I just bought new graphic card yesterday especially for SH5

I'll try to install 9.11 catalyst,maybe it will work then

You might want to use a tool called Drivercleaner or Drivercleaner pro, to delete some categories of registry entries after doing an uninstall. Current version is commercial, but I believe the older version is to be found on the internet. Just be abit careful where from or what you install should you consider this.
