To get the most out of SEUS PTGI (HRR Test 3 and beyond) in 2026, you must adjust the shader options correctly.
This is the most stable and performant version of SEUS PTGI for modern setups.
This shader pack is remarkable for several reasons:
Keep between 10-14, as PTGI is heavily dependent on ray tracing within that radius. Shadow Quality: Set to in Oculus/OptiFine menus . Alternate Blocks: Must be set to OFF . Natural Textures: Must be set to OFF .
