AMD and Microsoft stopped support for Win 8. Windows 8.1 is a free upgrade and has full support/drivers, etc., but the x1200 doesn't meet the requirements.
isthere a fix that will allow x1200 driver and CCC to operate on W8.1 x32/x64? You say "no support" but the web has several fixes using a modder.net file and legacy VISTA driver x32/x64.
I will do some more research and let you know what I find. I would like to know why x1200 and CCC cannot operate on W8.1 x32 or x64 using legacy drivers from VISTA and/or W7
I can't answer for a mod making it work, I can say the x1200 is too old for any OS later/newer than Vista. The WDDM requirements is just one of the problems.
i think you mean Win7 x32/x64....right????? I could be wrong.
- DXGI 1.1, which features return of hardware 2D acceleration for use by GDI (but not GDI+) and Direct2D/DirectWrite
- Direct3D 11 device driver interface (DDI)
- DXVA-HD DDI
- Hardware video overlay DDI
- Optional AES 128 encryption
- Optional decoding of encrypted video content
- Support multiple drivers in a multi-adapter and multi-monitor setup
Hardware acceleration of GDI and Direct2D/DirectWrite operations helps reduce memory footprint in Windows 7, because DWM compositing engine no longer needs to keep a system memory copy of all surfaces used by GDI/GDI+, as in Windows Vista.
DXGI 1.1, Direct3D 11, Direct2D, and DirectWrite were made available with Windows Vista Platform Update; however GDI/GDI+ in Vista continues to rely on software rendering and the Desktop Window Manager continues to use Direct3D 9Ex.
WDDM 1.1 drivers are backward compatible with WDDM 1.0 specification; both 1.0 and 1.1 drivers can be used in Windows Vista with or without the Platform Update.
Windows 8 includes WDDM 1.2 and DXGI 1.2. New features were first previewed at the Windows BUILD 2011 conference and include performance improvements as well as support forstereoscopic 3D rendering and video playback.
Other major features include preemptive multitasking of the GPU with finer granularity (DMA buffer, primitive, triangle, pixel, or instruction-level), reduced memory footprint, improved resource sharing, and faster timeout detection and recovery. 16-bit color surface formats (565, 5551, 4444) are mandatory in Windows 8, and Direct3D 11 Video supports YUV 4:4:4/4:2:2/4:2:0/4:1:1 video formats with 8, 10, and 16-bit precision, as well as 4 and 8-bit palettized formats.
WDDM 1.0/1.1 only allows rudimentary task scheduling using "batch queue" granularity; improvements to multitasking, as well as fast context switching and support for virtual memory, were initially expected in versions tentatively named WDDM 2.0 and WDDM 2.1, which were announced at WinHEC 2006.
Windows 8.1 includes WDDM 1.3 and DXGI 1.3. New additions include the ability to trim DXGI adapter memory usage, multi-plane overlays, overlapping swap chains and swap chain scaling, select backbuffer subregion for swap chain and lower-latency swap chain presentation. Driver feature additions include wireless displays (Miracast), YUV format ranges, cross-adapter resources and GPU engine enumeration capabilities.
Windows 10 includes WDDM 2.0, which is designed to dramatically reduce workload on the kernel-mode driver for GPUs that support virtual memory addressing, to allow multithreading parallelism in the user-mode driver and result in lower CPU utilization.
Direct3D 12 API, announced at Build 2014, requires WDDM 2.0. The new API will do away with automatic resource-management and pipeline-management tasks and allow developers to take full low-level control of adapter memory and rendering states.
thx for the WDDM versions...I wish I knew what it all means. It sounds like
I am hosed for the x1200 and CCC being used under Win8/8.1 x32/x64. Time to
Look at it on the brightside...now is the best time to upgrade a laptop...price-wise. Look for something that fully supports Windows 10 with DX12 support (if you play any PC games) or a laptop with Windows 8.1 if your not a gamer and do not want the intrusion of Windows 10.
