, which were optimized to work with the modern rendering pipelines used by Iris (Fabric/Quilt) and Oculus (Forge). Compatibility Overview Iris Shaders (Fabric/Quilt): SEUS PTGI HRR 2.1 and HRR 3 work natively with Iris. Iris is often preferred because it offers significantly better performance (higher FPS) compared to the traditional OptiFine setup. Oculus Shaders (Forge): Oculus is a Forge port of Iris. SEUS PTGI works with Oculus just as it does with Iris, allowing players on Forge-based modpacks to use path-traced shaders without needing OptiFine. Key Performance Features Entity Rendering Fixes: Recent versions of Iris/Oculus resolved previous "black screen" or "broken shadow" bugs that occurred when using SEUS PTGI. Path Tracing Support: Both shaders now correctly handle the custom buffer data required for SEUS to calculate global illumination and ray-traced reflections. No OptiFine Required: You no longer need OptiFine's closed-source code to run these high-end shaders; Iris/Oculus provides a more stable, open-source alternative.
