Example 1: Example scene where RTX really takes advantage of the scene. Really simple shading and just a lot of instances of a single object. It obviously has no issue tearing through this and scales beautifully. No depth of field, no volumes, etc.

Example 2: This time we have a scene with mass scattering and volumetric fog/scattering. In this example RTX still scales very well albiet not as much but still performs excelently compared to CUDA only.

Example 3: This scene has a decent amount of 4k different texture maps for all the different Megascan assets with a variety of shader properties, it also has some pretty heavy DOF. So this is a scene that RTX generally wouldn’t accelerate too much. Even then the results are still surprisingly good.

Example 4: In this final example we have a scene that has several instances but most of the geometry (leaves) consist of the sprite shader which can’t be accelerated by the RT cores. Even in this example though there are still a lot of regular pieces of geometry which can be accelerated like the branches on the trees. I also pushed the unified sampler pretty high to clean up the DOF as much as possible. Even though the sprite node doesn’t get accelerated by RT cores, all the geometry and DOF ray-tracing does, so it still provides a great boost in performance.
