Gaijin Studios also went on stage with their Enlisted game to showcase their particular implementation of NVIDIA's RTX - the first we've seen that was based not on Direct X 12, but on Vulkan. The highlights pointed out stuck with RTX's strengths, naturally, but particularly, with the ease with which the global illumination system was implemented. Essentially, the fact that Enlisted features massive, dynamic maps with up to 64 square kilometers, destructible environments and indoors and outdoors lighting conditions means that pre-baked illumination solutions just wouldn't cut it in any way - there were just too many variables to consider. RTX implemented via Vulkan was, for the studio, and as they put it, the tool they never knew they couldn't live without.
