Reshade Ray Tracing — Shader Rtgi 0.33

Ray Traced Global Illumination (RTGI) shader, developed by Pascal Gilcher (Marty McFly), is a sophisticated post-processing effect for ReShade that simulates real-time global illumination and ambient occlusion in almost any game. Unlike native ray tracing, it operates in screen space by tracing rays against the game's depth buffer, making it compatible with non-RTX GPUs. Key Features of RTGI 0.33

Where RTGI 0.33 Shines (And Where It Falls Apart)

Best-case games:

  • Dark / moody games (Dishonored, Thief, Resident Evil remakes) — the bounce light fills shadows with color from nearby surfaces.
  • Static camera or slow-paced games (Disco Elysium, XCOM, Civ) — temporal accumulation works perfectly.
  • Older games with baked lighting (Mass Effect Legendary, BioShock) — RTGI adds dynamic bounce light where none existed.

Frequently Asked Questions

Q: Will RTGI 0.33 work on my Intel integrated graphics? A: Possibly, but at 15 FPS. You need a dedicated GPU with at least 4GB of VRAM. Reshade Ray Tracing shader RTGI 0.33

The primary appeal of RTGI 0.33 is its universality. It allows players to "remaster" classic titles like Skyrim, Batman: Arkham City, or The Witcher 3 with lighting that rivals modern releases. Because it is an injector-based tool, it provides a bridge for gamers who have capable GPUs but play titles that were developed before the ray-tracing era.
