This is terrible testing. The only common denominator in the tables is the resolution. You have multiple configurations and settings all in one table which makes the results misleading and hard to read.
Tom's if this is what you have for reviews today you have problems.
Look, I don't know if it was added in after this comment or was already in there (which means you didn't read), but the second paragraph clearly states that this is only a sampling of configurations and is not to be taken as a well-done review.
Why is it bad, in a quickie review, to have configurations bundled together like they are? They show performance at 720p, 1080p, and 4k. I assume they skip 1440p for lack of time and because the 1440p/4k market overall is still extremely small and in the interest of time, they could only do one or the other. They also probably wanted to show people the highest settings they could achieve at a decent framerate (40+ avg fps at 1080p), hence combining low/high settings in one graph
Also, in a proper review, they would use a single high end processor along with standardized other components and just compare the graphics cards (or just compare cpu's), but this isn't a proper review and they admitted to it before showing you the results. Doesn't make it "okay", but also doesn't make it okay for you to bash the review for not being comprehensive when it was never intended to be.
I'm sure a comprehensive review will come out in due time. For now, at least you have some information about how you can expect your personal system to perform just by looking at how much better/worse your cpu/gpu are compared to the tested configurations.
What is very clear about this preview is that this is a very demanding game.
Looking at this, I should be able to get lowmedium settings on my 390 on 1440p. The game it probably one of the most visually appealing which is why it is so intense. It looks better than what Unity started out as last year.
I don't know about you guys, but most people who bash AC games as being unoptimized probably never played them and saw how gorgeous they really are.
I don't know why you have two resolutions listed for one graph though. It says 1080p/1200p?
1080p/1200p are essentially the same resolution with a difference of 230k pixels (or ~10%). 1440p/1600p are in the same boat with a roughly 10% difference in pixels.
And yea, AC games are notorious for being horribly optimized for PC and this preview shows it.
