AMD Radeon™ HD 4000 Series products and older are not certified to support Windows Display Driver Model (WDDM) 1.2 or higher and therefore, do not have driver support for Windows® 10. The following is a list of graphics products that do not support Windows® 10.
Hi I'm currently trying out the InsiderPreview for Windows 10, am I'm
looking for drivers for my old Radeon HD 4870.
The only statement I found by AMD is the one below. Are there yet drivers
by AMD or when will AMD release drivers for Windows 10? The build in
drivers for Windows 10 are working but they don't even allow the playback
of Videos.
*Q: Which AMD products are supported in the Windows® 10 technical preview? *
A: All AMD processors are compatible with the Windows® 10 technical
preview. In addition, all DirectX® 9-compatible (or higher) accelerated
processing units and AMD Radeon™ graphics cards are supported in the
Windows® 10 technical preview. Specific legacy products (e.g., AMD Radeon™
HD 4000 series) may require use of drivers provided by Microsoft® through
Windows Update with their Windows® 10 installation.
Thank you for your feedback.
Greetings
Michael
