Ok one more thing lol... I just did the same test on my desktop, which has a Ryzen 9 5900x, Nvidia 3080 12GB, 128 GB of 3600 RAM (lol), and Samsung 980 for the NVMe that Firestorm is running from. In the skybox its 20% better than my MBP, but at Muddy's I was able to get low 20s FPS in that crowd at least at times, so like 100% better:
