Reshade Ray Tracing Now

ReShade ray tracing demonstrates that screen-space approximations can deliver plausible real-time ray tracing effects on legacy hardware and unmodified games. Its primary trade-off is between performance and artifact suppression. While not a replacement for hardware-accelerated ray tracing, it democratizes access to global illumination and reflections for thousands of older titles. As denoising techniques improve and AI fills missing data, screen-space ray tracing will remain a relevant fallback and prototyping platform.

| Effect | Native RT (Reference) | ReShade SSRT | Notes | |--------|----------------------|--------------|-------| | Reflections | Accurate, off-screen | Only on-screen objects, edges flicker | ReShade fails for objects leaving screen | | Ambient Occlusion | Soft, distance-aware | Good for small details, halo artifacts | Temporal blur reduces noise | | Global Illumination | Diffuse bounces | Approximate – color bleeding works | Lacks distant light bounces | reshade ray tracing
