Compatibility with older graphics cards

does anyone know the general requirements of unity 2018 and how the new render pipelines affect compatibility with older systems…
i tried running beta 12 and 13 on an older pc and was getting frozen graphics, unresponsive GUI
but 2017 works fine.
the description for 2017 under Start Your Creative Projects and Download the Unity Hub | Unity
GPU: Graphics card with DX9 (shader model 2.0) capabilities. Anything made since 2004 should work

Wondering if there’s any such description about graphics cards for 2018?

Render Pipelines
The Lightweight Render Pipeline should work fine but HD Render Pipeline requires compute capable graphics card to work while Lightweight doesn’t (So it can run on a wide variety of hardware and platforms).

Editor
The Editor itself (Unity 2018.1) doesn’t have any new hardware requirements to run than 2017.3. DirectX 9 isn’t supported anymore since Unity 2017.3 both editor and Builds

Unity is moving to a Metal/Vulkan/DX12 future (11 is old now too but fully supported).
9 is no longer supported but you can:

  • Run under Vulkan
  • Use an older pre 2017.3 version
