| Parameter | Function | | :--- | :--- | | | Maximum distance a ray travels to find a surface. Higher = more bounce light but more performance cost. | | Intensity | Strength of the indirect lighting contribution. | | Bounce Count (Hidden) | Fixed in v0.33 to 1-2 bounces for performance reasons. | | Temporal Factor | How much the current frame blends with previous frames to reduce noise. | | Quality Mode | Low (performance) vs. High (visuals). High used 4 rays per pixel. | | AO Mix | Blends traditional ambient occlusion with ray traced AO for cleaner shadows. |
If you have an old game in your Steam library with dated lighting, download ReShade 4.9, find an archive of , and witness the magic of software-based path tracing. The frame rate may drop, but the immersion will skyrocket. Have you used RTGI 0.33 in your favorite retro game? Share your results and custom settings in the comments below.

While hardware ray tracing has since become mainstream (with UE5’s Lumen and RTX Remix), there is a certain charm to forcing a 2012 game like Dishonored to compute light bounces using a screen-space shader from 2021. It feels like hacking reality. | Parameter | Function | | :--- |
