My PC graphic card is the AMD Radeon HD 5750 and a long time ago I came across a thread on setting it up for optimal settings in general and I followed the instructions and it was fine. I have played first ED and now ED Horizons since day one and other than the problem with terrain that many Radeon users had at that time and which has been fixed I haven't had any problems at all. I was checking out the AMD support site for updates and read that the support for my card was ending due to the Crimson Edition but they would supply a link to a final beta Crimson update for my card. I checked it all out downloaded and installed it over a week ago and it has been fine. However I am an inveterate tinkerer and would like to optimize this update too but the GUI and settings for the Crimson software is entirely different to the old Catalyst Control version. Does anyone here have the Crimson software installed on their AMD graphics and care to share their settings?.
