SEUS PTGI does not use traditional Fragment Shaders for its lighting. Instead, it relies heavily on Compute Shaders .
No. SEUS PTGI (Sonic Ether’s Path Traced Global Illumination) does not work with Iris or Oculus. While Iris and Oculus are powerful modern shader loaders, they are built on a specific architecture that is currently incompatible with the specific type of rendering magic that powers PTGI. does seus ptgi work with iris or oculus
Migrating the complex, hacky path-tracing code of PTGI from OpenGL (OptiFine) to a modern abstraction layer (Iris/Vulkan) isn't just a matter of "fixing a bug"—it would require rewriting the entire shader pack from scratch. SEUS PTGI does not use traditional Fragment Shaders
