Reshade Ray Tracing Shader Rtgi 0.33 ((full)) Jun 2026

It cannot "see" what is behind the camera or off-screen. Lighting may disappear at the screen edges.

Navigate to your game’s installation directory where the .exe resides. Open the reshade-shaders\Shaders folder.

: It provides "micro-shadows" where objects meet the ground, preventing the "floating" look common in games with poor ambient occlusion.

Early versions of screen-space illumination suffered from "one-and-done" lighting, where light hit a surface and stopped. RTGI 0.33 features highly optimized multi-bounce approximations. When bright sunlight hits a red brick wall, the red light accurately bounces onto the concrete pavement, which then subtly reflects onto nearby objects. 2. Enhanced Temporal Filtering (Denoising) Reshade Ray Tracing shader RTGI 0.33

RTGI relies entirely on the game's depth map. If a game disables the depth buffer (often due to online anti-cheat software), RTGI will not work.

Ray tracing benefits from consistent frame delivery. Cap your frame rate to a stable 45 or 60 FPS using RivaTuner Statistics Server (RTSS) to eliminate micro-stuttering. Conclusion

Toggle this on to activate the 0.33 heuristic bounce system. It vastly improves realistic indoor lighting. It cannot "see" what is behind the camera or off-screen

When a ray hits an object in the depth map, it samples the color of that pixel.

Check the box for your game’s active depth path. Look for the resolution matching your display.

You can find the shader on Marty McFly’s Patreon (usually free after a short exclusivity period) or via the ReShade Discord server. Pair it with qUINT_ssr for reflections and MXAO for ambient occlusion, and you won't recognize your old games. Open the reshade-shaders\Shaders folder

: While RTGI supports various APIs, newer versions (including 0.33) have dropped official DX9 support; a Vulkan wrapper is recommended for older DX9 titles.

Keep this on "Spatiotemporal" to prevent the lighting from flickering when you pan the camera. Limitations of Screen-Space Ray Tracing

Look for the depth buffer list and check the box that matches your game's current resolution.
