The 2021 0.33 beta release brought massive optimizations, cleaner denoising filters, and better compatibility with DirectX 11, DirectX 12, and Vulkan titles. Key Features of the 2021 0.33 Release
Use a secondary ReShade shader called UIDetect or UI Mask placed above RTGI in your load order to mask out the HUD. 2. Flickering or Disappearing Lighting
If the depth map looks inverted or broken, toggle RESHADE_DEPTH_IS_REVERSED or RESHADE_DEPTH_INPUT_IS_UPSIDE_DOWN in the settings. Optimizing RTGI 0.33 Settings reshade ray tracing shader rtgi 033 2021
ReShade RTGI 0.33 proved that ray tracing’s visual appeal – soft shadows, color bleeding, and ambient occlusion – could be approximated without specialized hardware or engine support. For budget PC gamers and retro-modding enthusiasts in 2021, it turned old favorites into something that looked almost next-gen. And while modern games have since integrated hardware RT widely, RTGI 0.33 stands as a testament to what a single dedicated developer can achieve with clever screen-space algorithms and an open-source injection framework.

RTGI 0.3.3 accurately modeled both soft indirect light (diffuse) and reflections of light sources (specular). Why RTGI 0.3.3 Was a Game Changer in 2021
Unlike traditional screen-space effects (like SSAO) that only look at nearby pixels, uses ray tracing to simulate how light bounces off surfaces, producing realistic, physically-based indirect lighting in real-time. Key Features of the 2021 RTGI 0.3.3 Release
