If you have a backlog of 50+ classic PC games, an aging GTX 1070 or RTX 2060, and you want to feel like you just installed a $700 graphics card upgrade for free, then Reshade Ray Tracing shader RTGI 0.33 is still the king.

Practical considerations
ReShade RTGI 0.33 bridges the gap between legacy rasterization and modern path tracing. By utilizing advanced temporal denoising and intelligent screen-space mathematics, it breathes new life into older titles like Skyrim, Grand Theft Auto V, and The Witcher 3 . With a bit of patience and depth buffer tuning, you can transform your gaming library into a portfolio of next-gen visuals without buying a brand-new graphics card. If you want to tweak your setup further, let me know: What are you trying to mod? What graphics card (GPU) are you currently running?
If an object is not actively visible on your screen, it does not exist in the depth buffer. Therefore, a bright neon sign directly behind your camera will not cast light into the room in front of you until you turn around to look at it.

Released around August 2022, version 0.33 introduced several significant technical improvements: Motion Vectors Integration
This was a major addition that allowed the shader to track object movement across frames. This significantly reduces "ghosting" or trailing artifacts behind moving objects, a common issue in older screen-space shaders.
