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. reshade ray tracing
