Unlike the official builds that have largely dropped older backends, Ishiiruka retains support for DirectX 9 , which can be a lifesaver for users with very old GPUs. It also offers early and optimized DirectX 12 support for Windows users.
It includes built-in enhancements like SSAO (Screen Space Ambient Occlusion) , Depth of Field (DOF) , and advanced texture pre-fetching, making games look significantly better with less impact on performance.
Originally a standout feature for Ishiiruka, this eliminates the "stuttering" often felt when a game loads new effects for the first time.
