I tried this on another forum but didn't get much help. My brother plays on RCT3 (Roller Coaster Tycoon 3) and until I got a new graphics card (XFX 1gb 4890) it worked fine in vista 32bit. But since upgrading to this new card and installing the latest drivers it wont work. I have tried: 1. Compatibility mode. 2. Changing AA to 4x and less 3. Installing DX9 March redis although I already have DX10. 4. Installing the direct x9 from the disk but due to me having a later version the installer wouldn't do anything. 5. Installing the new 9.8 catalyst. Now I'm really stuck on what to do, does anyone have any suggestions. Thanks.
