An older, highly popular version known for crisp reflections.

Developed by Sonic Ether , SEUS PTGI is an experimental shader pack implementing a custom, software-based ray tracing architecture. Unlike hardware-locked RTX solutions, it calculates realistic lighting, bounce mechanics, and glossy reflections on any modern graphics card without requiring dedicated RT cores. : The essential performance engines (ports of Sodium)

To summarize the journey:

However, a war has been raging in the modding community between two rendering APIs: (for Fabric) and Oculus (the Forge port of Iris). Players constantly ask: Can I use SEUS PTGI on Forge with Oculus? Or do I need Iris? And what does "Top" mean?

For the absolute best Minecraft ray-tracing experience, combining with the Iris/Oculus engine beats traditional OptiFine setups in both stability and frames per second. If you are building a massive modpack on Forge , deploying Oculus ensures you do not have to sacrifice modern performance optimizations to enjoy Sonic Ether’s breathtaking global illumination.

Path tracing is extremely demanding. Fix: Lower the Render Quality and Shadow Resolution in the shader settings menu (press O ). For a 3060 Ti, expect around 40+ FPS with SEUS PTGI. For smoother gameplay at a lower visual cost, consider Complementary Shaders , which offers near-PTGI quality for significantly higher frame rates (91+ FPS).

: If referring to Intel Iris graphics, these integrated GPUs have varying levels of performance and compatibility with VR software, including Oculus. Some systems with Iris Xe graphics can run Oculus VR, but performance might be limited by the GPU.
