Don't forget Kaap you were using 200% resolution scaling, default is 100% resolution scaling and this is what was used in the tests above.Looking at the benchmark as it runs different settings make little difference to image quality. This is one game where turning down the settings to get it to run will make little difference to appearance, 1080p looks almost as good as 2160p.
Having said that the actual game may differ in appearance to the benchmark image quality wise.
