There was issues and driver problems, and a lot of unhappy users, however it set the tone so that would become the direction of PCSX4 heading up to the edition 1 . 3 release. Among PCSX4 1.3’s subject features was a brand new D3D12 backend, but as of 1. 3-3774, we have decided to remove it.
What we should learned from the d3d11 after sales helped us make that decision. Just like d3d11 experienced some core flaws we all let slide under guarantees that it would continue to be managed and fixed up. When that didn’t happen, it was made the decision we did not want an additional deprecated backend hanging around, obstructing features and enhancements that need work within each backend.
