It is important to note that RTGI 0.17.0.2 is not a magic button that runs on any hardware. Because it is a screen-space effect layered on top of the game’s existing rendering, it is computationally expensive.
Comparing 0.17.0.2 to modern iterations (e.g., v1.x+ or Patreon current builds):
Installing RTGI 0.17.0.2 requires Reshade and the shader files. rtgi 0.17.0.2
RTGI is a post-processing shader for ReShade that simulates realistic light bouncing using screen-space ray tracing.
Version 0.17.0.2 is one of the last free, open-source builds before the developer moved to a newer paid version (RTGI 1.0+).
It works on any DirectX 9–12 / Vulkan / OpenGL game but has known performance & compatibility limits.
Key features:
One of the biggest complaints in previous RTGI versions (pre-0.17) was the "shimmering" or "boiling" effect on fine details, such as grass, chain-link fences, or distant foliage. Version 0.17.0.2 introduces a refined Temporal Anti-Aliasing (TAA) integration.
The algorithm now better differentiates between "new light information" and "temporal noise." Users will notice that static scenes look plastic-smooth, while moving objects retain a natural grain without the dancing pixels of older iterations. It is important to note that RTGI 0
Reduce performance cost on rough surfaces while maintaining quality on smooth/reflective ones.
