I have an integrated gpu radeon hd 7660d, its dx 11.2 and i'm wondering if it can somehow run dx12 games
I think you need to run that through the translator again. And the 7660d is a desktop APU. How can you possibly think that turd can even run modern games? You would need a gpu at least 6 to 7 times faster just to meet bare min requirements in any halfway modern demanding games.
The GPU is based on the uArch from 2010's HD 6000 series. It supports: DirectX 10.1 (and bellow) DirectX 11 (Feature Level 11_0). So no God of War 2018 for example OpenGL 4.4 on Windows. On Linux it supports OpenGL 4.6 with vastly better performance. Same as DX11 performance on Windows or FASTER. On Windows performance might be boosted with Zink. Vulkan: No support DirectX 12: No support FSR 2.0: No support FSR 1.0: Available in games with DX11 support (where FSR 1.0 is also available of course). Can be injected externally also with Lossless Scaling and Magpie on DX11 and bellow and OpenGL. FreeSync / Enhanced Sync: No support You can play any emulators that support DX11 or OpenGL, but you need Windows 10 or 11. Windows's WDDM level support: 1.3 (Windows 8.1 feature level). You might actually have W10 WDDM 2.0, but I'm not sure (that requires just DX11)
