oxide are calling this one a benchmark... none of the reviewer have commented on how repeatable it is or how many runs they did (that I can see), so where it falls is currently unknown until people get their hands on it and we see some more testing of different scenarios
that would certainly explain the odd results, if the reviewers are averaging runs and not mentioning it, that would explain getting higher fps at higher res if its just a rounding error
Oxide was calling Starswarm a benchmark as well

But what they were doing is just showcasing what different APIs can do while maintaining certain fps.
AotS the data outpust is a bit more organised, but it is still showing a lot of different numbers which influence each other. As is most of the time with reviewers they just rush things out, and rarely take a better look what they are rushing out.
And then we have everyone talking how AMD drivers are bad for dx11, how nvidia is crying and how performance increase when increasing resolution. Excel charts on its own will never tell us full picture.
It is a shame that we have such review sites who have no clue what they are actually benchmarking.
On the other hand game code is in alpha state, dx12 is out for just several weeks, drivers are young, and game was showcased on AMD hardware many times. Why some people jump the gun and declare that this is end all results, I have no clue, though I must admit, watching nvidia release a driver for this game and few days later cry how this is buggy and not representative is extremely fun. Can we imagine what kind of performance we would have gotten out of nvidia if they did not release game ready drivers? Some would say the game was completely unplayable before nvidia release new drivers

But there is no need to concentrate on that, since again, everything is in early stages.
