Nvidia RTX 3080: PCIe 4.0 vs 3.0 scaling analysis

Total War Saga: Troy is a 2020 turn-based strategy video game developed by Creative Assembly Sofia and published by Sega. The game was released for Windows on 13 August 2020 as the second installment in the Total War Saga subseries, succeeding Thrones of Britannia (2018). (Wikipedia).

Engine: TW 3 Engine. We test using the Ultra preset, DX11 API.

Total War Saga: Troy does show some performance gains with PCIe 4.0. Granted, the 10900K system is still faster at 1080p, but the 3900XT with PCIe 4.0 is 3% faster than the same CPU with PCIe 3.0. In fact, at 1440p, that lead actually grows to 4%. Again, not really a game changer, but one of the largest difference we have seen today.
