Use Iris Shaders . It is the original high-performance shader mod built for Fabric and is natively compatible with Sodium.
The dream of is a chimera—a beautiful, impossible assembly of incompatible technologies. Iris and Forge cannot coexist; path tracing cannot yet sustain VR framerates; and the Oculus VR mods are not optimized for advanced shader pipelines. However, the pursuit of this "top" tier setup highlights the incredible creativity of the Minecraft modding community. Each component pushes the boundary of what a decade-old block game can achieve. For now, players must choose: path-traced beauty on a flat screen (Fabric + Iris + SEUS PTGI) or immersive VR with traditional shaders (Forge + Vivecraft + SEUS Renewed). True convergence remains a future milestone—one that will likely require a complete rewrite of Minecraft’s rendering engine and next-generation GPUs. Until then, compatibility is a game of trade-offs, not a checklist of features. seus ptgi iris compatibility oculus forge top
Generally compatible with both Iris and Oculus. Use Iris Shaders
If you run Forge + Oculus for PTGI, you cannot run Sodium (Fabric's performance mod). You must use or Embeddium (Forge ports of Sodium). Unfortunately, Rubidium often conflicts with Oculus when PTGI tries to access translucency buffers, leading to water becoming invisible. Iris and Forge cannot coexist; path tracing cannot
