Running RTGI at a lower internal resolution multiplier within the shader settings heavily boosts performance with minimal loss to lighting accuracy.
Yes! RTGI is fully compatible with non-RTX video cards. It operates on depth data alone and has no inherent hardware feature requirements. That said, ray tracing is demanding work, so older or low-end cards may struggle with higher quality settings.
Before you attempt a download and install, ensure your PC meets these specs:
Searching for cracked, free, or "full" zip archives of RTGI on untrusted forums or file-sharing sites poses severe risks. Malicious actors frequently package malware, trojans, and crypto-miners into fake shader files. reshade rtgi 033 download full
Copy the contents of the RTGI Shaders folder into reshade-shaders/Shaders .
Light sources emit rays that strike surfaces, pick up their colors, and bounce onto surrounding objects (color bleeding).
Because it only calculates screen-space data, it provides a ray-traced aesthetic at a fraction of the performance cost of hardware-native ray tracing. Understanding the "Full Download" and Legality Running RTGI at a lower internal resolution multiplier
Offers better compatibility with modern graphics APIs. System Requirements
: Modded or older cracked versions often fail to communicate with ReShade’s depth buffer, rendering the ray tracing completely non-functional or glitched.
Your game folder should now look something like this: It operates on depth data alone and has
Go to the tab (located at the top of the ReShade UI).
RTGI 0.33 allows you to run the shader at half or quarter resolution. Setting this to half-resolution provides a massive performance uplift while temporal filters smooth out the lower-res lighting.
Once RTGI is active, you will see a performance drop. Use these configuration tweaks in the ReShade panel to balance visual quality with frame rate.
Unlike native ray tracing, RTGI works on almost any GPU, including older non-RTX cards, because it relies on depth data rather than dedicated hardware. Improved Lighting:
