Today, NVIDIA and DICE revealed to have partnered on Battlefield 2042 not only to add NVIDIA DLSS and NVIDIA Reflex as previously announced, but also ray traced ambient occlusion effects, whereas Battlefield V featured ray traced reflections. This won't be available on next-generation consoles.

Ray tracing refines graphics, creating more realistic scenes that help immerse you in the action. In Battlefield 2042, EA and DICE are introducing Ray-Traced Ambient Occlusion, which accurately adds shadows where game elements occlude light. Be that between a soldier and a wall, a tank and the tarmac, or foliage and the ground.
