Practical Tips for Optimizing Ray Tracing

Nvidia

Technically, you can use shader atomic increments to account for all the rays on each frame if needed. This can be partially achieved using a bindless resource model where all required resources are available directly from the shader code on GPU without explicit CPU-side bindings. Shader table data and updates.

Best Practices for Using NVIDIA RTX Ray Tracing (Updated)

Nvidia

Flagging instances or geometries as opaque allows uninterrupted hardware intersection search and prevents invocation of the any-hit shader. Enable the use of any-hit shaders only for those geometries that need it; for example, to do alpha testing. Consider alpha testing instead of blending. Do this whenever possible.

Optimize Vegetation Generation

Mnenad

Doing it before starting the actual game would mean to already generate all the content that needs to be batched at the beginning, which is no solution for a theoretically “endless procedurally generated” terrain.  When batched, the animations from the Advanced Foliage Shader go a bit crazy and make the grass float around.
