O/S: Windows Pro 8.1 64-Bit (DirectX ver. 11)
I have just upgraded from Windows XP Pro 32-Bit O/S (SP3) using ATI Catalyst Driver ver. 8.930.0.0 12/05/2011 at the time, to the new Windows 8.1 Pro 64-Bit O/S.
Before upgrading to Windows 8.1, I was able to run LA/TG's "Xwing Alliance" flightsimulation game flawlessly with "ddraw.dll" file in the game's main XWA directory. When using the current ATI driver packages with Windows 8, the XWA game engine no longer uses "Primary Display Adapter 3D Accelerated Hardware Mode (with or without Mipmapping enabled) but defaults to Software Mode only which looks horrible.
The oldest ATI Catalyst driver package 12.10 (October 2012) for Windows 8 partially works in a very limited way, but I get frequently black screens with no display of moving 3D craft objects. The game engine is 16/32 bit application. Used a custom .msi installer with no problems. Just the D3D DirectX9 drivers (in-flight) rendering seem to be the issue. Is there a work around or future driver patch for backwards compatiblity of older classic DirectX applications? Rather frustrating. Thanks!
