will see , i'm on 17134.1 and for me nothing wrong , no bug , same in control panel , i have not bug when choose default app
Well they are different engines. FC5 runs with more FPS, but it's almost always a "guy in the woods" experience. ACO actually has large cities with lots of population and AI going on, FC5 at best has those bases with 10 defenders. If you go out of the city and roam around some desert in ACO you'll pretty much have the same FPS as in FC5, it's just the large cities that are heavy on both CPU and GPU. IMO both are quite well optimized, although ACO could do better with Vega and FC5 with Pascal. It's just that ACO is kinda ahead of its time with the crazy CPU requirements inside a city, I've seen my 8700K go to 70-80% and on the web 4 core CPUs like 7700K are at 100% in those areas.
yeah true aco is alot heavy than far cry 5 in many diffrent ways from the maps and desing in graphics.in desert someone can big diffrence in fps easy.
while I can agree with some of your points i.e. different graphics engines(FC5 has Dunia engine & ACO has AnvilNext & ACO is bigger than FC5 in terms of open word settings & environment & NPC & map, but I will still say than ACO is poorly optimised, maybe its just the different graphics engine that they've used. Also, Wildlands used the same AnvilNext 2.0 like ACO, but still it's better optimised than ACO if you compare both within a same GPU engine bracket
