Yes it does..... AMD Radeon R9 M280X - NotebookCheck.net Tech
" The AMD Radeon R9 M280X is a 28 nm DirectX 12 graphics card based on the GCN (Graphics Core Next) architecture. Built primarily for large laptops, the card is positioned in the upper mid-range category as of 2014. "
However, you have switchable graphics.....a integrated R7 chip and the discrete R9 chip. So your choice of driver depends on the OS. Do you have Win10 or Win 8.1?
I have windows 10 home. So the card does support dx12. But why i cannot run forza in this laptop?
