My son recently bought the Steam version of DCS A-10 for me as a gift. I read the forums, and therefore, I first downloaded and installed the DCS world (all four files). I then downloaded the A-10 module from the DCS site, and installed it. I then started up the game, and got a screen asking for my key. In input the key from Steam, and it loaded up. I see all the menus. I picked the low texture options, to start, and tried to load up instant action. All I got is a green screen. I had sound, and the red text marking items in the game, but everything else was just a green screen. I then tried the training missions, with same results. I have the Intel I5 computer with 6mb of RAM. I am running Windows 7 64 bit. I have dual ATI Radeon HD 5670video cards and am using Crossfire. I am using drivers 8.850.0.0, which ATI says are the latest drivers. What am I doing wrong? Or can my system not handle this? I am running Falcon BMS 4.32 and Microsoft FSX with no problems. Help!
