Goal: 1440p/4K gaming with SEUS PTGI at 120+ FPS. Your primary friction point is Fabric vs

The first and most decisive barrier is the loader conflict. Iris is built exclusively for Fabric, a lightweight mod loader. Forge uses a completely different API. They cannot run together in the same Minecraft instance without a compatibility layer like Sinytra Connector (which is unstable for rendering-heavy mods). Therefore, if you want Iris to load SEUS PTGI, you must be on Fabric. However, the VR mod named "Oculus" (for Fabric) is specifically designed for that loader. So in theory: Fabric + Iris + SEUS PTGI + Oculus (Fabric VR mod) seems plausible. OptiFine + Forge (using OptiForge or manual install)

If you want full, flawless SEUS PTGI (including volumetric fog, proper path tracing, and no artifacts), your only reliable choice remains:

OptiFine + Forge (using OptiForge or manual install).

But wait—OptiFine is slow on modern versions (1.20.1+)? Yes. But for PTGI specifically, the rendering engine matters more than FPS tricks.
