Seus Ptgi Iris Compatibility Oculus Forge Top

For a long time, SEUS PTGI was a luxury reserved only for OptiFine users. But as the Minecraft community shifted toward high-performance mods like Sodium, a "compatibility bridge" was needed. This is where the story of Iris and Oculus begins. The Two Paths to Ray Tracing

Depending on which mod loader you use, your setup will look different:

The Forge Path (Oculus): If you use Forge, you cannot use Iris directly. Instead, you use Oculus, which is an unofficial Forge port of Iris. It is designed to work with Rubidium (a Forge version of Sodium) to give you the same performance boost. seus ptgi iris compatibility oculus forge top

The Fabric Path (Iris): If you are on Fabric, you use the official Iris Shaders. It’s built to work seamlessly with Sodium for massive FPS gains. Making SEUS PTGI Play Nice

2. Oculus (Forge) – SEUS PTGI Compatibility: Better, but not perfect

Oculus is a Forge port of Iris. It shares the same shader parser. Therefore, Oculus has identical compatibility with SEUS PTGI as Iris (partial).

However, if you must use Forge mods (Create, Mekanism, etc.), Oculus is your only lightweight option. SEUS PTGI HRR 2

Part 5: The "Top" Alternatives – PBrutality and Continuum

If you cannot get SEUS PTGI to work with Oculus on Forge, you have two "Top Tier" alternatives that offer near-identical path tracing with perfect Iris/Oculus compatibility:

  1. BSL Shaders (with PTGI path tracing mod): Less realistic reflections, but 40% faster than SEUS on Oculus.
  2. Complementary Shaders (Reimagined): Does not use true path tracing, but uses fake "screen-space" ray tracing that looks 90% as good as SEUS PTGI but runs natively on any Oculus version without glitches.

Path A: The Performance King (No VR, No Forge)

Goal: 1440p/4K gaming with SEUS PTGI at 120+ FPS.

Step 3: Download Oculus

Oculus is the bridge. Download the latest Oculus .jar file (matches your Rubidium version). Place both Rubidium.jar and Oculus.jar into your mods folder.
