Critically, RTGI operates on depth data alone. This hardware independence means it is fully compatible with non-RTX video cards and has no inherent hardware feature requirements, though ray tracing is fundamentally demanding. It uses innovative methods to accelerate ray marching, often outperforming hardware-accelerated ray tracing on meshes reconstructed from depth input. However, due to its screen-space nature, it can only directly observe surfaces currently facing the camera, which sometimes requires workarounds or adjustments.
Note: RTGI 0.17.0.2 still relies on , not RT cores. Therefore, Nvidia GTX cards and AMD RX 5000 series run it comparably to low-end RTX cards. rtgi 0.17.0.2
To evaluate the performance of rtgi 0.17.0.2, we conducted a series of tests using various scenes and hardware configurations. The results are summarized below: Critically, RTGI operates on depth data alone
You must install the "Add-on Support" version of ReShade to ensure the shader can access the game's depth buffer, which is required for ray tracing. However, due to its screen-space nature, it can
She walked the avatar—her own ghost—down the digital hallway. The old bug, specular bleed , was gone. Previously, the white trim of the doorframe would glow like a radioactive strip, smearing its brightness onto the flowered wallpaper. Not anymore. The light touched the trim, bounced once, and fell gently onto the roses. It felt heavy . Real.
This version relies on a voxel-based approach for indirect lighting calculations, distinct from earlier pure screen-space methods.
The world of computer graphics and game development is constantly evolving, with new technologies and techniques emerging to push the boundaries of visual realism. One such innovation is RTGI (Real-Time Global Illumination), a cutting-edge technology that enables developers to create stunning, lifelike environments with unprecedented levels of accuracy and performance. The latest iteration, RTGI 0.17.0.2, promises to take real-time global illumination to new heights.
