Delete everything that doesn't affect the ray trace view. For example, if you are creating a ray trace of a kitchen on Floor 1, begin by selecting File> Save As and making a copy of the file with a unique name like "kitchen_ray_trace.plan". Then, delete the foundation, Floor 2, and even furnishings, fixtures, and lights on Floor 1 that cannot be seen from the kitchen.

Use bounding objects to fail fast. Project the scene at a first step (as common graphic cards do) and use raytracing only for light calculations. Parallelize the code.
Speed-Up Techniques for Ray Tracing Field Prediction ...
https://ieeexplore.ieee.org/abstract/document/4909458/references
Abstract: Despite their good performance, the widespread diffusion of ray tracing field-prediction models is still limited due to their high complexity and high computation time. In this paper, two different classes of methods for speeding up ray tracing urban field prediction are proposed, aimed at reducing the size of the input database and the number of rays to be …

Ray-scene intersection takes most of the CPU time (Whitted: up to 95%) scene composed of elementary solids –sphere, box, cylinder, cone, triangle, polyhedron, .. –primitive solids in CSG –number of elementary solids .. N naïve algorithm tests every ray (up to the proper recursion depth H) against every elementary solid

Speeding Up Ray Tracing. ©Anthony Steed 1999, Celine Loscos 2005, Jan Kautz 2007-2009. Optimisations. • Limit the number of rays • Make the ray test faster. – for shadow rays. • the main drain on resources if there are several lights. – for primary rays – for all rays. Over 90% of the cost of ray tracing is in ray-object intersection tests.

12 Tips To Speed Up Your Rendering
https://www.renderro.com/blog/rendering-speed-up-guide/
1. Turn off Ray-Traced 3D. This is extremely important even though the ray-tracing function is something very innovative. However, if you want a fast render time, make sure you have a classic 3D setup before starting it. This can speed up the process up to two times!
How Does Ray Tracing Improve GPU Performance? | ITIGIC
https://itigic.com/how-does-ray-tracing-improve-gpu-performance/
The rendering method generally used in video games is the so-called rasterization or painter’s algorithm.But with the arrival of Ray Tracing or Ray Tracing in real time we are approaching an era in which old limitations are completely overcome. With the arrival of AMD‘s RDNA 2 and new generation consoles, it is clear that we are not facing a passing fad and that …
