Removes a bug introduced in v1.2.3: the DLSS clip-space jitter block was emitted into every vertex shader and read the Position output before writing it. Reading an unwritten output is undefined, so vertex positions could come out as garbage - whole 3D passes landing nowhere (the green screen reported on GYLT, Ghostbusters, Blair Witch and others) and the black block artifacts in Xenoblade Chronicles 2's motion-blur pass, which had been mistaken for a long-standing emulation defect and worked around by disabling the effect. With jitter off - how this fork ships - the vertex epilogue is now identical to the base emulator again, and the motion blur no longer needs to be disabled. CodeGenVersion bumped so existing shader caches are rebuilt. Also adds a DLSS sharpening slider (0-100, off by default) and an experimental advanced motion stack checkbox (off by default).
Documents Index
This repo includes several documents that explain both high-level and low-level concepts about Ryujinx and its functions. These are very useful for contributors, to get context that can be very difficult to acquire from just reading code.
Intro to Ryujinx
Ryujinx is an open-source Nintendo Switch emulator, created by gdkchan, written in C#.
- The CPU emulator, ARMeilleure, emulates an ARMv8 CPU and currently has support for most 64-bit ARMv8 and some of the ARMv7 (and older) instructions.
- The GPU emulator emulates the Switch's Maxwell GPU using either the OpenGL (version 4.5 minimum), Vulkan, or Metal (via MoltenVK) APIs through a custom build of OpenTK or Silk.NET respectively.
- Audio output is entirely supported via C# wrappers for SDL3, with OpenAL & libsoundio as fallbacks.
