This scene is made to just look good on screenshots. If you want to capture some, it will work well for you. Otherwise it is wildly un-optimized for actual gameplay. It sports 6 forcepixel pointlights, 2 forcepixel spotlights, all casting shadows, and a realtime high-res mirror atom. It will tank your FPS no matter what you do, and without IL atoms the environment looks bad. The author knows about baking, yet decided to use IL atoms. On R9 7900X3D, RTX 4080 Super, 64GB fast RAM just adding two basic person atoms brings fps down to 40 in VR. This is without any plugins applied, animations, collisions, just a clean test. Hard to imagine what it will do to weaker rigs.
Again, probably a good screenshot material. And the artistic direction is nice. Not playable, unfortunately.
What is prioritized varies by user and creator.
